1
00:00:06,280 --> 00:00:08,200
Speaker 1: Hey, hey, hey, welcome back ron Any in the car.

2
00:00:08,240 --> 00:00:10,639
Speaker 1: Doctor here. Let's go over and talk to Keith Hempstead,

3
00:00:10,680 --> 00:00:13,200
Speaker 1: North Carolina two Lincoln Town Car Yes, sir.

4
00:00:13,640 --> 00:00:14,600
Speaker 2: Hey, how you doing good?

5
00:00:14,640 --> 00:00:14,880
Speaker 1: Sir.

6
00:00:15,520 --> 00:00:17,840
Speaker 2: I've got a problem with when I started to give

7
00:00:17,840 --> 00:00:21,480
Speaker 2: approach highway speed, I started to feel a viperation of

8
00:00:21,600 --> 00:00:24,759
Speaker 2: vibration in the car. It's kind of cycles and I

9
00:00:25,840 --> 00:00:28,960
Speaker 2: know I have the tires rotated and spend a line

10
00:00:29,000 --> 00:00:33,600
Speaker 2: and everything, and it feels like it's like a mechanical vibration,

11
00:00:34,280 --> 00:00:36,720
Speaker 2: like I said, goes away when I slower my.

12
00:00:36,720 --> 00:00:39,920
Speaker 1: Speed, it feels like it's in the seat of your pants.

13
00:00:40,000 --> 00:00:40,280
Speaker 2: Keith.

14
00:00:40,720 --> 00:00:43,680
Speaker 1: Yeah, you know, if you're cruising along what speed? Does

15
00:00:43,720 --> 00:00:46,200
Speaker 1: it come in at about fifty five?

16
00:00:46,320 --> 00:00:49,239
Speaker 2: And it starts getting worse as I increased speed, like

17
00:00:49,320 --> 00:00:51,800
Speaker 2: on the highway speed at seven it seems to be

18
00:00:51,840 --> 00:00:52,320
Speaker 2: the worst.

19
00:00:52,560 --> 00:00:56,400
Speaker 1: Does it ever level off where it just totally disappears.

20
00:00:56,240 --> 00:00:59,279
Speaker 2: It totally disappears when I when I slow down, when

21
00:00:59,280 --> 00:01:01,840
Speaker 2: I get you know, I blow fifty five or just disappear.

22
00:01:01,920 --> 00:01:02,640
Speaker 2: I can't see.

23
00:01:02,640 --> 00:01:05,160
Speaker 1: So it starts at fifty five and it'll get gradually worse.

24
00:01:05,200 --> 00:01:08,880
Speaker 1: If you were doing eighty's it's just as it's still

25
00:01:08,920 --> 00:01:11,080
Speaker 1: there in some shape or form that you can.

26
00:01:10,959 --> 00:01:13,600
Speaker 2: File it right. I've tried to speed up some and

27
00:01:13,680 --> 00:01:15,600
Speaker 2: to see if it was just that particular steed. It

28
00:01:15,600 --> 00:01:18,319
Speaker 2: seems to get maybe a little worse with increasing speed.

29
00:01:18,560 --> 00:01:21,560
Speaker 1: Did rotating the tires at all change anything, or just

30
00:01:21,760 --> 00:01:24,440
Speaker 1: didn't matter, didn't matter, didn't make a difference.

31
00:01:26,120 --> 00:01:29,240
Speaker 2: That was word. It could be like a drive train issue.

32
00:01:29,040 --> 00:01:31,840
Speaker 1: Or well, what's going on in my mind is, well,

33
00:01:31,840 --> 00:01:34,880
Speaker 1: first of all, a couple of things. Number one, Even

34
00:01:34,880 --> 00:01:37,680
Speaker 1: though somebody tells me they had the tires rotated and balanced,

35
00:01:38,240 --> 00:01:40,200
Speaker 1: I still want to be certain that the tires were

36
00:01:40,240 --> 00:01:45,240
Speaker 1: balanced properly. Because I probably solve seven out of ten

37
00:01:45,360 --> 00:01:48,120
Speaker 1: vibration complaints that come into the shop that people have

38
00:01:48,200 --> 00:01:51,440
Speaker 1: been everywhere and everybody's tried everything, and YadA YadA yah.

39
00:01:51,600 --> 00:01:53,560
Speaker 1: I end up putting the tires on the balancer because

40
00:01:53,600 --> 00:01:55,720
Speaker 1: I have a set procedure. I still follow, you know,

41
00:01:55,800 --> 00:01:59,840
Speaker 1: I still go ABCD, and I still find seven out

42
00:01:59,840 --> 00:02:02,920
Speaker 1: of ten times somebody's got a tire that's out of balance.

43
00:02:02,960 --> 00:02:05,960
Speaker 1: That may not solve the problem altogether every time, but

44
00:02:06,040 --> 00:02:08,920
Speaker 1: it changes it so it becomes a combined, layered issue.

45
00:02:09,120 --> 00:02:13,080
Speaker 1: So my first thought is be absolutely certain and you know,

46
00:02:13,960 --> 00:02:16,560
Speaker 1: did it look like they did the tire balance correctly?

47
00:02:17,120 --> 00:02:20,000
Speaker 1: And that's the first step. The second is, yes, it's

48
00:02:20,120 --> 00:02:23,799
Speaker 1: very possible once we eliminate tires as a potential source,

49
00:02:24,040 --> 00:02:26,640
Speaker 1: that they're not chopped cupped, that the tires are in

50
00:02:26,680 --> 00:02:29,880
Speaker 1: good condition, and that they are in balance. That this

51
00:02:30,000 --> 00:02:33,000
Speaker 1: is a drive train issue. Specifically, this is a town car,

52
00:02:33,440 --> 00:02:37,040
Speaker 1: so this is a rear wheel drive vehicle, right, okay,

53
00:02:37,200 --> 00:02:40,280
Speaker 1: That this could have either a bad universal joint or

54
00:02:40,320 --> 00:02:42,920
Speaker 1: a drive shaft that is out of balance because a

55
00:02:42,960 --> 00:02:46,400
Speaker 1: weight fell off of it one word or the other. Now,

56
00:02:46,520 --> 00:02:48,520
Speaker 1: one of the things your mechanic could try to do

57
00:02:49,320 --> 00:02:53,079
Speaker 1: if he wants to see if doing work on the

58
00:02:53,160 --> 00:02:56,040
Speaker 1: drive shaft changes anything, or if it affects the vibration,

59
00:02:56,120 --> 00:02:58,680
Speaker 1: tell them to take a two hose, clamps and some

60
00:02:58,760 --> 00:03:03,079
Speaker 1: wheelweights and clamp it. Start off with two ounces, three ounces,

61
00:03:03,120 --> 00:03:05,440
Speaker 1: four ounces, depends on how he wants to diagnose this

62
00:03:06,160 --> 00:03:08,760
Speaker 1: and clamp it to the rear of the drive shift.

63
00:03:09,080 --> 00:03:11,760
Speaker 1: Does it change the vibration? Does it help the vibration

64
00:03:12,400 --> 00:03:14,600
Speaker 1: all right? For that matter, if he were to run

65
00:03:14,600 --> 00:03:17,600
Speaker 1: the car up in the air at thirty miles an hour,

66
00:03:18,600 --> 00:03:21,520
Speaker 1: watch the drive shift. Does it look like it's spinning? Oblong?

67
00:03:21,560 --> 00:03:25,120
Speaker 1: Does it look like it's spinning? True? Okay, I mean

68
00:03:25,160 --> 00:03:26,880
Speaker 1: there's a bunch of things you can do before you

69
00:03:26,919 --> 00:03:29,240
Speaker 1: actually go and pull the shaft out and have it

70
00:03:29,360 --> 00:03:32,480
Speaker 1: checked for balance and vibrate and square, you know, one

71
00:03:32,520 --> 00:03:34,560
Speaker 1: important thing. And I don't know what the access is

72
00:03:34,600 --> 00:03:36,880
Speaker 1: down in North Carolina to a drive shaft shop. I mean,

73
00:03:36,880 --> 00:03:39,760
Speaker 1: I'm sure they're around, but again I always stress to

74
00:03:39,800 --> 00:03:43,560
Speaker 1: everybody a good tire balance, a good drive shaft shop.

75
00:03:43,720 --> 00:03:46,720
Speaker 1: They're all kind of hard to find today, right, But

76
00:03:46,800 --> 00:03:49,120
Speaker 1: if he's got somebody he can send it to, you

77
00:03:49,160 --> 00:03:51,720
Speaker 1: may want to consider part of the diagnosis. Hey, here's

78
00:03:51,760 --> 00:03:54,360
Speaker 1: my drive shift. Is it square? And how do the

79
00:03:54,440 --> 00:03:58,280
Speaker 1: joints feel? All right? I'd be more thinking along the

80
00:03:58,320 --> 00:04:02,160
Speaker 1: lines of a balance or a bent drive shaft then

81
00:04:02,200 --> 00:04:05,240
Speaker 1: a joint, because generally a bad you joint comes in

82
00:04:05,240 --> 00:04:07,640
Speaker 1: at about thirty two miles an hour, goes out at

83
00:04:07,680 --> 00:04:10,640
Speaker 1: forty five, comes in at fifty five, goes out at

84
00:04:10,680 --> 00:04:13,920
Speaker 1: sixty eight. Somewhere in that range. It seems to be

85
00:04:13,960 --> 00:04:16,520
Speaker 1: about a ten to twelve mile an hour spread starting

86
00:04:16,560 --> 00:04:19,760
Speaker 1: at thirty two to forty five fifty five to sixty

87
00:04:19,760 --> 00:04:21,640
Speaker 1: eight and so on. It kind of clip clops works

88
00:04:21,680 --> 00:04:24,640
Speaker 1: its way up the cycle. But you know, a drive

89
00:04:24,680 --> 00:04:27,400
Speaker 1: shift could clearly be it as far as a potential

90
00:04:27,440 --> 00:04:28,000
Speaker 1: source for this.

91
00:04:28,960 --> 00:04:31,000
Speaker 2: Okay, all right, Oh, thanks for hill.

92
00:04:31,080 --> 00:04:32,920
Speaker 1: You're welcome, sir. Have him checked that and then, by

93
00:04:32,960 --> 00:04:36,480
Speaker 1: all means, give me a call back. Hey, let's let's

94
00:04:36,520 --> 00:04:42,839
Speaker 1: go from here. Good grief, it's carcare corner time. Let's

95
00:04:42,839 --> 00:04:45,720
Speaker 1: get over there and see what's going on. Your car

96
00:04:45,920 --> 00:04:49,599
Speaker 1: or truck's transmission needs to have the fluid changed on

97
00:04:49,640 --> 00:04:52,440
Speaker 1: a regular basis, and it also needs to have the

98
00:04:52,480 --> 00:04:55,960
Speaker 1: filter replaced if it's so equipped. Now, if you notice

99
00:04:56,000 --> 00:04:59,160
Speaker 1: I said your vehicles transmission, your car, truck. I didn't

100
00:04:59,160 --> 00:05:01,560
Speaker 1: say if it was a man annual or an automatic.

101
00:05:01,640 --> 00:05:05,159
Speaker 1: I said your transmission. Transmissions need to be serviced. That's

102
00:05:05,200 --> 00:05:09,920
Speaker 1: a fact manufacturers have talked about and pointed out that

103
00:05:09,960 --> 00:05:14,039
Speaker 1: there are extended drain and change intervals as vehicles have

104
00:05:14,120 --> 00:05:17,039
Speaker 1: gotten better. And yes, they have gotten better, but the

105
00:05:17,160 --> 00:05:21,839
Speaker 1: fact remains. Changing fluid and filter on your vehicle's transmission,

106
00:05:21,839 --> 00:05:24,320
Speaker 1: as well as the rest of the drive train can

107
00:05:24,440 --> 00:05:28,039
Speaker 1: help increase the longevity and life of the vehicle so

108
00:05:28,120 --> 00:05:31,880
Speaker 1: that you can drive it longer with less problems. Part

109
00:05:31,920 --> 00:05:34,520
Speaker 1: of a good transmission service, What are some of the

110
00:05:34,520 --> 00:05:36,960
Speaker 1: things you need to look for? First of all, for

111
00:05:37,000 --> 00:05:41,720
Speaker 1: an automatic transmission, you're going to remove the pan, change

112
00:05:41,720 --> 00:05:44,320
Speaker 1: the filter if it's so equipped, and most of them

113
00:05:44,320 --> 00:05:47,720
Speaker 1: today are. You're going to replace the fluid in the pan.

114
00:05:48,160 --> 00:05:51,480
Speaker 1: If there is a drain on the torque converter, you're

115
00:05:51,520 --> 00:05:53,960
Speaker 1: going to have that drained and then refill it during

116
00:05:53,960 --> 00:05:57,400
Speaker 1: the refilled process. Or you're going to service the filter

117
00:05:57,520 --> 00:05:59,840
Speaker 1: the fluid in the pan, put it back up, and

118
00:06:00,240 --> 00:06:04,240
Speaker 1: do a fluid exchange for a complete fluid replacement. This

119
00:06:04,360 --> 00:06:07,640
Speaker 1: is done generally while the vehicle is running. It removes

120
00:06:07,760 --> 00:06:09,760
Speaker 1: all the fluid out of the torque converter and the

121
00:06:09,760 --> 00:06:12,320
Speaker 1: rest of the transmission that just dropping the pan won't

122
00:06:12,360 --> 00:06:15,479
Speaker 1: get to, and provides good clean fluid back to the

123
00:06:15,520 --> 00:06:22,120
Speaker 1: transmission throughout its entirety, and generally it works great. Dirty nasty,

124
00:06:22,200 --> 00:06:25,560
Speaker 1: rotten fluid comes out and good clean fluid goes back

125
00:06:25,600 --> 00:06:28,080
Speaker 1: in that transmission. Sure performs a whole heck of a

126
00:06:28,120 --> 00:06:32,400
Speaker 1: lot better. Manual transmissions are generally a little easier to service.

127
00:06:32,800 --> 00:06:35,839
Speaker 1: They are a draining fill. The most important thing you

128
00:06:35,880 --> 00:06:38,960
Speaker 1: need to do there, just as with an automatic transmission,

129
00:06:39,000 --> 00:06:41,560
Speaker 1: but the choices aren't as great. You need to be

130
00:06:41,760 --> 00:06:44,960
Speaker 1: certain that you've got the correct type of gear oil

131
00:06:45,040 --> 00:06:48,360
Speaker 1: going back into that manual trans Not all gear oils

132
00:06:48,360 --> 00:06:51,440
Speaker 1: are the same, not all automatic transfluids are the same.

133
00:06:51,920 --> 00:06:56,440
Speaker 1: Bottom line is that your vehicle's transmission, regardless of what

134
00:06:56,560 --> 00:06:59,640
Speaker 1: it is, needs to be serviced on a regular basis.

135
00:07:00,040 --> 00:07:03,480
Speaker 1: If it's so equipped, filters along with the fluids, a

136
00:07:03,520 --> 00:07:05,719
Speaker 1: fresh pan gasket if it needs it if it's not

137
00:07:05,760 --> 00:07:09,640
Speaker 1: a reusable one, a converter change if it's an automatic,

138
00:07:10,000 --> 00:07:13,720
Speaker 1: and make sure absolutely that you're putting correct fluid back

139
00:07:13,760 --> 00:07:15,840
Speaker 1: in it, whether it be an automatic or a manual,

140
00:07:16,160 --> 00:07:20,520
Speaker 1: and that vehicle's transmission will keep going for more miles

141
00:07:20,840 --> 00:07:25,560
Speaker 1: and more miles, and more miles and more miles. This

142
00:07:25,640 --> 00:07:27,720
Speaker 1: has been the Carcare Corner with me ronning Annie in

143
00:07:27,760 --> 00:07:34,800
Speaker 1: the car doctor. Hey, welcome back, ronnin Anie in the car.

144
00:07:34,880 --> 00:07:35,040
Speaker 3: Doc.

145
00:07:35,200 --> 00:07:37,360
Speaker 1: Let's go over and talk to Bob Philipsburg, New Jersey,

146
00:07:37,440 --> 00:07:41,640
Speaker 1: nineteen ninety folkswagon wabbit and see what's going on over there. Yes, Bob, welcome,

147
00:07:42,000 --> 00:07:42,520
Speaker 1: good morning.

148
00:07:42,600 --> 00:07:44,960
Speaker 4: Yeah, last time I talked to you, I got the

149
00:07:45,000 --> 00:07:47,640
Speaker 4: air conditioning working and the engine just went away with

150
00:07:47,920 --> 00:07:50,480
Speaker 4: oil pressure and then everything else. So I got the

151
00:07:50,520 --> 00:07:54,520
Speaker 4: engine and transmission out of the car, took the transmission

152
00:07:54,560 --> 00:07:58,400
Speaker 4: completely apart to reseal it because it was leaking right,

153
00:07:58,720 --> 00:08:03,000
Speaker 4: and the ATF oil is really really beat up bad

154
00:08:03,200 --> 00:08:05,679
Speaker 4: in fact, how to replace some bushings in the clutch

155
00:08:05,760 --> 00:08:09,920
Speaker 4: packs and everything else, And I'm thinking about putting synthetic

156
00:08:09,960 --> 00:08:13,280
Speaker 4: oil for the automatic. I did put synthetic oil into

157
00:08:13,320 --> 00:08:17,880
Speaker 4: final drive with this. Any Fani's over at Dextron three.

158
00:08:17,760 --> 00:08:20,040
Speaker 1: Or You're not going to rebuild the trends, right, Bob,

159
00:08:20,040 --> 00:08:21,880
Speaker 1: You're just gonna it's just a reseal.

160
00:08:22,400 --> 00:08:26,960
Speaker 3: Yeah, Basically, I probably wouldn't at this point because I

161
00:08:27,000 --> 00:08:29,240
Speaker 3: would just use you know, I would probably just use

162
00:08:29,240 --> 00:08:33,239
Speaker 3: conventional transfluid at this stage of the game I'm concerned

163
00:08:33,280 --> 00:08:35,600
Speaker 3: with and synthetic transfluid has its place.

164
00:08:35,600 --> 00:08:39,040
Speaker 1: Synthetic transfluid works well in a lot of transmissions. I

165
00:08:39,040 --> 00:08:41,600
Speaker 1: don't know Volkswagen off the top of my head. But

166
00:08:41,920 --> 00:08:44,720
Speaker 1: the reason I'm hesitating without doing some research on it

167
00:08:44,760 --> 00:08:46,760
Speaker 1: isn't if you want, you can do the research yourself.

168
00:08:47,240 --> 00:08:50,640
Speaker 1: Is just because some of the synthetic fluids are so

169
00:08:50,760 --> 00:08:53,840
Speaker 1: slick they can actually create an issue with friction and

170
00:08:53,880 --> 00:08:56,800
Speaker 1: clutch packs in the trends and cause an early failure.

171
00:08:57,760 --> 00:08:59,520
Speaker 1: And I'm not saying that as a negative. I think

172
00:08:59,559 --> 00:09:03,040
Speaker 1: synthetic transfluid has its place, like synthetic engine oil has

173
00:09:03,040 --> 00:09:05,400
Speaker 1: its place. Just be sure of what you're putting it in.

174
00:09:05,480 --> 00:09:10,040
Speaker 1: Some of the early nineties Ford products, for example, synthetic transfluid,

175
00:09:10,640 --> 00:09:13,160
Speaker 1: we have found that it does cause issues and does

176
00:09:13,240 --> 00:09:16,319
Speaker 1: create bigger problems, and it can cause an early failure

177
00:09:16,400 --> 00:09:19,360
Speaker 1: some vehicles. It works really well in now some of

178
00:09:19,360 --> 00:09:22,240
Speaker 1: the newer vehicles two thousand and six model year and

179
00:09:22,320 --> 00:09:24,840
Speaker 1: up on. A lot of manufacturers are now going to

180
00:09:24,880 --> 00:09:28,840
Speaker 1: a synthetic trans fluid. So you know it has its place.

181
00:09:29,280 --> 00:09:31,920
Speaker 1: It's just like conventional engine oil as far as you

182
00:09:31,920 --> 00:09:34,600
Speaker 1: know heat breakdown, on all the issues that it'll help prevent.

183
00:09:35,000 --> 00:09:37,040
Speaker 1: But you've got to know what you're putting it into.

184
00:09:37,520 --> 00:09:38,079
Speaker 3: Yeah.

185
00:09:38,440 --> 00:09:41,280
Speaker 4: As far as the engine, last time we had talked

186
00:09:41,320 --> 00:09:44,040
Speaker 4: about this, I had to end up getting a used

187
00:09:44,080 --> 00:09:47,600
Speaker 4: engine because of my resources. I had two places I

188
00:09:47,640 --> 00:09:52,280
Speaker 4: could have gotten engines, but the reliability wasn't there. The

189
00:09:52,320 --> 00:09:55,000
Speaker 4: engine came out of a place is to deal strictly

190
00:09:55,040 --> 00:09:57,560
Speaker 4: with watercoal volkswag as they keep the cars on the

191
00:09:57,559 --> 00:10:01,040
Speaker 4: steel racks. You can't even go in there. Angine's guaranteed,

192
00:10:01,600 --> 00:10:05,680
Speaker 4: but brand new oxygen and sensor. And I don't dropped

193
00:10:05,679 --> 00:10:07,960
Speaker 4: it in a bucket of waste oil. What do you think.

194
00:10:11,000 --> 00:10:13,640
Speaker 1: I think you're buying. I think you're buying an oxygen sensor.

195
00:10:13,920 --> 00:10:16,440
Speaker 4: Yeah, it was one of those days. Everything. I just

196
00:10:16,840 --> 00:10:18,720
Speaker 4: you know, you just dropped the things, you know. I

197
00:10:18,720 --> 00:10:20,600
Speaker 4: think we do make mistake right, I mean.

198
00:10:20,559 --> 00:10:24,120
Speaker 1: Listen, that's why God put erasers on pencils. Yeah, you

199
00:10:24,120 --> 00:10:26,440
Speaker 1: could try it, Bob, but I don't think you're gonna

200
00:10:26,480 --> 00:10:28,000
Speaker 1: get any response out of it. I think for the

201
00:10:28,040 --> 00:10:30,240
Speaker 1: price of an O two, I've got to say, I

202
00:10:30,240 --> 00:10:32,600
Speaker 1: don't think I've ever run across that one. My concern

203
00:10:32,720 --> 00:10:34,920
Speaker 1: is that the oil is saturated into the into the

204
00:10:34,960 --> 00:10:38,040
Speaker 1: poorest material that the O two sensor contains. Yeah, I

205
00:10:38,040 --> 00:10:41,160
Speaker 1: don't think it would ever correct itself. I just I

206
00:10:41,160 --> 00:10:43,920
Speaker 1: think you're throwing it away, yeah, okay, or you're gonna

207
00:10:43,960 --> 00:10:45,520
Speaker 1: you're gonna mount it on a piece of wood, put

208
00:10:45,559 --> 00:10:47,800
Speaker 1: it on your toolbox and go. Haste makes waste. And

209
00:10:47,840 --> 00:10:48,840
Speaker 1: here's an example of it.

210
00:10:48,920 --> 00:10:51,120
Speaker 4: I got lots of fabulous veil. I got quite a

211
00:10:51,160 --> 00:10:52,520
Speaker 4: fabulous Vail here collection.

212
00:10:52,760 --> 00:10:55,360
Speaker 1: So there you go, there you go, all right, sir.

213
00:10:55,360 --> 00:10:57,240
Speaker 4: Okay, I'll let you know how to make out.

214
00:10:57,320 --> 00:11:00,560
Speaker 1: Yep, thank you. Yeah. It's always we alway, you know,

215
00:11:00,600 --> 00:11:03,040
Speaker 1: it's just and we do it. That's what makes us human.

216
00:11:03,120 --> 00:11:04,760
Speaker 1: We do tend to rush and we can kind of

217
00:11:04,840 --> 00:11:08,520
Speaker 1: run around and you know, just not something you really

218
00:11:08,559 --> 00:11:10,520
Speaker 1: want to go through. If you don't have to, Let's

219
00:11:10,640 --> 00:11:15,080
Speaker 1: let's go over and talk to Christina out there in Glenburn, Maine. Yes, Christina, Yes.

220
00:11:15,240 --> 00:11:19,200
Speaker 5: I have a ninety seven Toyota Corolla, okay, and I've

221
00:11:19,240 --> 00:11:22,520
Speaker 5: been having problems with it the front end breake wise.

222
00:11:23,160 --> 00:11:27,360
Speaker 5: They replaced the Toyota the caliber on the passionate side,

223
00:11:27,600 --> 00:11:29,520
Speaker 5: thinking it was that because you go down the road

224
00:11:29,960 --> 00:11:31,720
Speaker 5: and you'll be just going down the road and all

225
00:11:31,760 --> 00:11:34,640
Speaker 5: of a sudden you'll feel the whole front end start shaking, okay,

226
00:11:34,720 --> 00:11:37,080
Speaker 5: because the calipers the brakes are coming on.

227
00:11:37,480 --> 00:11:41,360
Speaker 1: So the brakes are applying by themselves with your foot off. Yeah,

228
00:11:41,440 --> 00:11:44,920
Speaker 1: all right. Can the mechanic duplicate the problem?

229
00:11:44,960 --> 00:11:48,760
Speaker 5: It doesn't happen all the time because it comes, it

230
00:11:48,840 --> 00:11:52,360
Speaker 5: goes off and on. It doesn't happen all the time.

231
00:11:52,600 --> 00:11:55,400
Speaker 1: Does the car pull to one side or the other,

232
00:11:55,559 --> 00:11:57,840
Speaker 1: or it just stops straight, It just starts to slow

233
00:11:57,920 --> 00:11:59,319
Speaker 1: down in a fairly straight line.

234
00:11:59,480 --> 00:12:02,920
Speaker 5: Right, exactly fairly straight line, starts to slow down. They're

235
00:12:02,960 --> 00:12:06,720
Speaker 5: thinking that's the proportioning valve, but I'm not really sure.

236
00:12:07,679 --> 00:12:10,960
Speaker 1: I'd be thinking more along the lines of a master cylinder,

237
00:12:11,600 --> 00:12:16,199
Speaker 1: because if the master cylinder wasn't applied and the proportioning

238
00:12:16,280 --> 00:12:19,280
Speaker 1: valve was stuck one way or the other, it doesn't

239
00:12:19,280 --> 00:12:20,920
Speaker 1: have any pressure in it that it would allow the

240
00:12:20,960 --> 00:12:23,800
Speaker 1: system to apply to the calibers to slow the car down.

241
00:12:24,200 --> 00:12:26,800
Speaker 1: In other words, the proportioning valve is controlled by the master.

242
00:12:27,600 --> 00:12:31,240
Speaker 1: If the master cylinder isn't activating anything, you could take

243
00:12:31,240 --> 00:12:32,920
Speaker 1: that proportioning valve and move it all the way to

244
00:12:32,960 --> 00:12:35,959
Speaker 1: the left of the right in theory from a mechanical

245
00:12:36,040 --> 00:12:38,920
Speaker 1: understanding of it, and it's not going to matter. It

246
00:12:38,960 --> 00:12:41,640
Speaker 1: doesn't know, it's not going to affect anything because there's

247
00:12:41,679 --> 00:12:44,240
Speaker 1: no pressure in the system. What I would suggest the

248
00:12:44,280 --> 00:12:46,640
Speaker 1: mechanic try to do is if he can duplicate the

249
00:12:46,720 --> 00:12:49,160
Speaker 1: problem once it gets to the point, and let me

250
00:12:49,240 --> 00:12:51,640
Speaker 1: ask you this question. If the wheels start to lock

251
00:12:51,720 --> 00:12:54,760
Speaker 1: up and the car stops. If you wait a certain

252
00:12:54,800 --> 00:12:57,679
Speaker 1: amount of time, does it free itself? Or does this

253
00:12:57,840 --> 00:13:01,079
Speaker 1: just go on forever it frees itself? Okay? How long

254
00:13:01,080 --> 00:13:02,640
Speaker 1: does it take for it to free itself?

255
00:13:03,280 --> 00:13:04,079
Speaker 5: An hour or so?

256
00:13:04,320 --> 00:13:06,760
Speaker 1: Okay? I bet you this car has a bad master.

257
00:13:06,800 --> 00:13:08,640
Speaker 1: I bet you the seals and the master are swelling

258
00:13:08,720 --> 00:13:11,960
Speaker 1: and not releasing the piston. Or this could also have

259
00:13:12,000 --> 00:13:14,600
Speaker 1: a bad break booster causing the master cylinder to be

260
00:13:14,600 --> 00:13:17,480
Speaker 1: applied by engine vacuum and affecting it that way. Pulling

261
00:13:17,480 --> 00:13:19,000
Speaker 1: the pedal down, does the pedal drop it?

262
00:13:19,040 --> 00:13:19,199
Speaker 2: All?

263
00:13:19,600 --> 00:13:19,800
Speaker 5: No?

264
00:13:20,040 --> 00:13:23,720
Speaker 1: All right, try this the next time it happens. Have

265
00:13:23,840 --> 00:13:26,679
Speaker 1: you tried popping the brake pedal with your foot, hitting

266
00:13:26,679 --> 00:13:29,079
Speaker 1: it hard, or lifting up from underneath trying to get

267
00:13:29,080 --> 00:13:32,800
Speaker 1: it to release. Yes, you've pulled up from underneath, yep. Okay.

268
00:13:32,920 --> 00:13:36,480
Speaker 5: If you completely stopped right and then try to go right,

269
00:13:36,600 --> 00:13:38,480
Speaker 5: it sounds like you have your emergency brake on.

270
00:13:38,880 --> 00:13:41,920
Speaker 1: Okay. It shutders And this happens while traveling at speed

271
00:13:41,960 --> 00:13:43,839
Speaker 1: and you have not touched the brake.

272
00:13:43,600 --> 00:13:44,720
Speaker 5: Pedal right exactly?

273
00:13:44,840 --> 00:13:47,360
Speaker 1: Okay. Get the mechanic to duplicate it. When he does,

274
00:13:47,880 --> 00:13:52,240
Speaker 1: tell him to break the line. Crack it loose at

275
00:13:52,280 --> 00:13:55,240
Speaker 1: the master cylinder and see if fluid burps out. If

276
00:13:55,280 --> 00:13:58,000
Speaker 1: the fluid burps out at the line at the master cylinder,

277
00:13:58,200 --> 00:14:00,720
Speaker 1: that vehicle's got a bad master or some things causing

278
00:14:00,720 --> 00:14:03,080
Speaker 1: it to apply and he can diagnose it from there.

279
00:14:03,240 --> 00:14:03,680
Speaker 1: All right.

280
00:14:03,960 --> 00:14:07,079
Speaker 5: He said something about when he pulled, when he pulled

281
00:14:07,080 --> 00:14:10,560
Speaker 5: the plug on the caliber, that the brake food just

282
00:14:10,559 --> 00:14:11,280
Speaker 5: squirt it out.

283
00:14:11,440 --> 00:14:14,040
Speaker 1: Right, Well, where's the brake fluid coming from the master cylinders?

284
00:14:14,040 --> 00:14:16,719
Speaker 1: Building pressure? That's your bigger issue. Do it the way

285
00:14:16,760 --> 00:14:18,880
Speaker 1: I said, I think you'll get to the solution. I'm

286
00:14:18,920 --> 00:14:43,040
Speaker 1: Ronning a in the Car Doctor. We'll back right after this. Hey,

287
00:14:43,080 --> 00:14:45,040
Speaker 1: welcome back Ronning Anie in the Card Doctor here. So

288
00:14:45,080 --> 00:14:47,720
Speaker 1: we're kind of winding things down, finishing off our article

289
00:14:47,760 --> 00:14:50,560
Speaker 1: about the credit issues and how the housing market has

290
00:14:50,560 --> 00:14:53,920
Speaker 1: affected the automotive market and how a lot of you

291
00:14:54,000 --> 00:14:56,440
Speaker 1: are thinking maybe he's now is not a good time

292
00:14:56,480 --> 00:14:58,440
Speaker 1: to purchase a new vehicle. And I'm sort of sitting

293
00:14:58,480 --> 00:15:00,720
Speaker 1: here scratching my head thinking maybe now's the time we

294
00:15:00,760 --> 00:15:03,400
Speaker 1: ought to talk more about fixing cars and repairing cars.

295
00:15:03,400 --> 00:15:05,880
Speaker 1: So I think in some upcoming shows we're gonna point

296
00:15:05,920 --> 00:15:07,440
Speaker 1: out some of the things that you need to be

297
00:15:07,480 --> 00:15:10,240
Speaker 1: looking for, either in a used car purchase or what

298
00:15:10,280 --> 00:15:12,600
Speaker 1: you consider doing to your vehicle. Trying to help you

299
00:15:12,640 --> 00:15:15,480
Speaker 1: make that decision fix it or replace it, and we'll

300
00:15:15,520 --> 00:15:18,520
Speaker 1: kind of talk about that as the week's unfold. The

301
00:15:18,640 --> 00:15:21,680
Speaker 1: article concludes that the economy weekens further or the housing

302
00:15:21,760 --> 00:15:24,360
Speaker 1: market weekends further, there will be a continued impact on

303
00:15:24,360 --> 00:15:28,400
Speaker 1: automotive sales. Sixty percent of new automotive sales or financed,

304
00:15:28,440 --> 00:15:31,800
Speaker 1: and a significant portion of that comes from home equity loans.

305
00:15:31,800 --> 00:15:34,760
Speaker 1: If the sources of those down payments try up, it concludes,

306
00:15:34,800 --> 00:15:37,960
Speaker 1: it may affect future sales figure. So housing market definitely

307
00:15:38,000 --> 00:15:40,920
Speaker 1: affects automotive market. We'll see where all of the this goes. Hey,

308
00:15:41,000 --> 00:15:42,800
Speaker 1: till the next time when we get together, continue the

309
00:15:42,880 --> 00:15:44,920
Speaker 1: quest to fix all of the America's broken cars. I'm

310
00:15:44,960 --> 00:15:47,960
