I was wondering if 1979 Dodge Vans had regular 727 transmissions, or 727 with lock ups? I was told that Chrysler switched to the lock-ups in mid year. How to confirm this? I was also told that if you use a trans on a 318 that had a lock up it would cause a vibration in the drive train at high speeds, and might damage seals in the engine and trans.
View 1 RepliesI have a 2007 dodge Dakota with 112K miles. At 105K I had the front brake rotors and pads replaced. The rear brakes were fine. There was a problem with one of the rotors and I returned a week or two later and one, which was warped, was replaced. Ever since that second visit I have had an intermittent vibration from the vehicle. When I brake the whole truck vibrates. And by vibrating, I mean some pretty heavy shaking. It is not the steering wheel vibrating. I took this back to the mechanic where they were unable to find any issues with the brakes. Also, we could not (of course) re-create the issue while it was in the shop. I have not been able to find the pattern. It happens when I am braking at high speeds, but not every time. It also happens at lower speed, but again, not every time.
View 2 RepliesI just recently lowered my mk6 with h&r springs(1.2 front and rear) and installed wheels and tires from tire rack. I am noticing a lot of vibration at the wheel, pedals and seats while accelerating or moving at higher speeds. I had an alignment done after the springs were installed and all 4 tires/wheels have been road force balanced. One of the tires rated at 20lbs which apparently is acceptable but Tire rack sent me a new tire anyway, which I just had put on today.
Still the same vibration is there. Next step tire rack wants to do is switch out all 4 of my Michelin for a different tire. The guys at tires plus feel that there is no issue with the tires and I think I agree. Could the lowering springs be the problem?
My wife has an Acura, and when braking at higher speeds, she is getting a really bad "vibration". I am assuming the rotors are warped. We had both axles (rotors/pads) done last year (about 40k ago) at Midas. After they did them, we had to take the car back about 3 times for squeaky pads, and I swear a slight vibration, but they didn't fix them. Anyway, even though they offer "lifetime pads," I refuse to go back there.
So, her pads now started squeaking again. We were dealing with the warped rotors until we had some extra money and time to take it in. At this point, I am wondering where I should take it. I have no clue if the pads are good, and I'm guessing the rotors just need to be turned since they were just put on last brake job.
I have a '79 D100 that needs a new distributor. I've removed the two necessary bolts that I know of. I've tried to twist it, and will will barely turn. I've tried to pry it up. I've loosened a few bolts in the area to see if that relieved pressure. I've degreased the area and sprayed WD40 at the base of it and still nothing.
View 3 RepliesI have a 4-cyl 2003 Camry LE with a bit of a vibration issue, but first, some backstory.
I put in new tires about 20,000 miles back and I started to notice a pull to the left side and no amount f alignment would fix it and there was no other discernible issue with the front end.
I read about how some tires have some internal issues with the radial belts and I decided to rotate the tires. No more pull. It didn't change the fact that the tire may be defective and still causing issues.
Could a tire that caused a strong pull on the front end cause a vibration at high speeds in the rear?
I have a 2008 Chevrolet Trailblazer. I have had 4 of these vehicles and have been very pleased. This latest one has 61000 miles and occasionally has a very strange vibration at speeds above 60 mph. It only happens occasionally and most often occurs at these higher speeds and worsens with increased speed (of 70-73 mph). The vibration is so alarming, that I will press my brakes to slow down, because it feels like the vehicle is starting to lose control. The problem is that when I press the brakes, the vibration intensifies about 3-4 fold! It feel as if the wheels are going to come off. It's a very frightening feeling. I have taken it to the shop and no one seems to know what it is. The tires are fine. Brakes are fine. Interestingly enough, if I lower the speed to 50-55 mph, the vibration lessens and eventually completely goes away.
View 1 RepliesGetting some vibration at high speeds on the highway, and when I changed my wheels, I noted that there seems to be some free play in the ball joint on the end. Is this normal? Can I replace just the end of the tie rod?
View 3 RepliesI purchased a 2003 F-150 Screw a few months back. Within a week I noticed a noise that sounded like a bad ujoint. To it to a shop and they confirmed it. They told me they replaced both. I only drive about 4 miles to work around 40 mph. Friday I had to go out of town and this was the trucks 1st road trip. I noticed that around 55 the truck feels fine. At 65 there is a shake / vibration. At 75 it is very noticeable. At 1st I though front end, but after a few hour I noticed the feeling can be felt in the seat of my pants type of thing. Or my foot on the kicker panel. Truck has 27K on it.
View 4 RepliesSo when i hit ~80km/h (50 miles) some weird extremely small vibration is coming on. You cannot feel it from anywhere but when u touch something, like handbrake then its there. Tho the sound is kinda loud. So the pattern is like, 0.3 seconds it is vibrating and 0.3 is quiet, it does not matter on which road i drive.
This problem cannot be caused by wheels (got other alloys and same problem), also already got alignment and have balanced my wheels. So, what to do?
I have a 2009 Chevy Malibu that gives through rotors every 6 months. I have replaced them 3 times now in 102,000 miles and had them turned multiple times. What happens is about 6,000 miles after I put new rotors on they warp and I get a violent vibration when braking at high speeds. I have been to 3 different dealerships and none of them can figure out why they continue to warp.
View 12 RepliesI have a 2004 Honda Accord EX (4 cyl) with 102k miles. I bought it brand new and kept it completely in shape with regular service. For the past few months I start getting front end vibration at braking, mostly when slowing from high speeds and without any repair this vibration has now became common at all speed.... my diagnosis - I need to replace to turn disk/rotors....
While I have not remedy the rotor issue yet, I started getting this new vibration at 60 to 80 mph.... Below and above this range of speed i have no vibrations - the car will drive fine. This type of vibration in my experience for front wheel drives is mostly due to balancing or bad tires. so i took the easy way ..... and as i already needed tires well i dished out the dough and replaced all four with Michelin Primacy hoping that it will resolve the speed related vibration.... Well it did not?
I continue to drive as-is without addressing the real problem - coz I'm not sure what is causing the vibration.... now new additional vibration started on acceleration; any time I hit the gas pedal (normal acceleration or kick-down) I get vibration very similar to when a stick shift's gearbox required replacement/repair of the worn out pressure plate's (fingers/springs gets bent or weak) or the thrust bearing needs replacements/repair/grease packing. I'm from the old school stickshift transmission, my knowledge in automatic is very little - I have repaired Acura's automatic transmission before but I don't think repairing once will make me an expert in automatic.
So to summarize my issues or current state:
Issue# 1 front end vibration on braking
Issue# 2 front end vibration 60 to 80 mph speed only
Issue# 3 front end vibration on acceleration at all speed
The list above is in sequential order as I have experienced.
I recently noticed squeaks and some vibration on my drivetrain and to my surprise i must change my axles... now i have looked around and pricing is between 300 and 400$ for each (passenger and driver side) this was at ECStuning and UroTuning. both say its a genuine VW part. front axle 1.8t 6speed gli....
View 11 RepliesI just bought a 2002 corolla with a salvage title. I am having trouble with the front passenger side vibration at high speeds 50mph on up. It had the vibration when I bought it and I put 4 brand new tires on it, and had the front end aligned and had a fellow mechanic look at it and and said everything up front was tight. The guy I bought it from said he had the front brakes just done but I feel a pulsating as when I apply the brakes. My fellow mechanic said he would turn the rotors next week, my question is what would be my next step if that not it, axle? I really wouldn't car but I drive this car 150 miles a day to work and its all highway.
View 2 RepliesThis has been happening for the past 6 months or so. I recently had new ball joints, 4 wheel alignment, and 4 wheel balance. Even with this I'm noticing a very slight high frequency vibration at highway speeds. I noticed on one of the front wheels that a weight fell off, so this might explain the high speed vibration.
However - When I'm starting at 0mph, and accelerate to say 50mph for example, the car vibrates rather substantially as the speedometer moves from around 25mph to just past 30mph. After those speeds it goes away.
I've also noticed that it tends to be worse if I'm going up hill, which, according to the laws of physics, would tell me that going uphill would put more pressure on the front end, given it's heavier with the engine there. If I'm going downhill it vibrates much less.
When I drive I tend to not accelerate quickly, meaning, I don't 'punch' it, and accelerate gradually instead. If I'm driving on a level, well-paved road, and accelerate quicker than regular, the vibration seems to not be as heavy.
Any other tests for this? Struts, control arm, steering knuckle, drive shaft ?
I just bought a new 2010 supercrew 4x4 lariat. I have 2000 mles on it. vehicle is equipped with 20" wheels with scorpion tires. Problem is that ride is very hard plus there is really annoying low level vibration that seems to be related to drivetrain - this vibration is most noticable on smooth roads. i have owned 99, 03, 05, and 08 4x4 lariat supercrews and this is by far the worst riding truck. i put a lot of miles on my trucks and this one is not in the least enjoyable to drive.
I took it back to ford dealership and they just said that these new bodies are 'stiffer' and transmit more vibration and that new 6 speed transmission is not as smooth. I reduced tire pressure from 40psi (as delivered) to 35psi with no difference. I don't buy it - I believe that something is wrong that can be fixed - but not sure where to look. Other than this problem i really like the truck!
Recently purchased my first Prius, it's the v wagon.
When accelerating from a stopped position in eco mode there's a relatively severe drivetrain shutter/vibration for a a short period of time until I back off the throttle, almost feels like a clutch slipping with added vibration.
It's probably a normal noise produced by this style transmission, just looking to verify if this is true so I can stop worrying about it.
I have a 04 F350 srw , 6.8 . Recently developed loud whine from the rear . I had the differential (10.5 sterling ) completely rebuilt . It quieted way down . But I still had a couple of high pitched whines . Took it back and had the rebuilder ride with me . At first he couldn't hear it ( it can be faint but gets louder under a load , I pull a 40' trailer and didn't have it with me), when he finally started hearing it he said it might be a planetary making a little noise, just watch it . So I made a short run (450miles RT) . Same noises but I noticed that sometimes when I stopped and got fuel , it would quiet down for 50 or so miles . I got to thinking maybe it could be a rear wheel bearing going bad and the sound transferring through the axle to the drive line . It only did it accelerating ( before and after rebuild ) and got louder going up a hill .
Today I drove it in to town and parked it ( still the same ) and a couple of hours later after a cold front came through ( maybe 10 Deg. temp change) I got in and the noise was about 90% gone , but at 45 to 60 mph. it vibrates . Let off the gas , vibrates ,, Put it in neutral- vibrates, revved the engine in neutral - vibrates and no change from rpm diff. . As long as its rolling between 45-60 , it vibrates . Hit the brakes- vibrates.. I have had 3 mechanics check it out ( 2 good ones and one that the other 2 take what they cant figure out ). Left them all scratching their heads. Checked the driveline and I changed one U joint (prior to the short run ). All seems tight .
79 F150 400/C6 2wd. Loss of reverse and it doesn't want to stay in high.
Strange thing happened today. I took my truck on it's longest test drive since rebuilding the transmission. It was about 25 miles. I got to the junk yard just fine and it was running just fine when I left. I went through a drive through to grab a burger and headed home. That's when it started acting funny. It shifted fine 1st to 2nd, then 2nd to 3rd, but it wouldn't stay in 3rd. It would shift into high, but the slightest bit of throttle and it would shift back into 2nd and eventually got so bad that it just stayed in 2nd, so I had to return to the town I was leaving.
I drove to an autoparts store nearby. I decided to move where I was parked and when I put it into reverse, nothing was there. It rolled back. I drove it to the new spot and called for a tow truck. Weird thing is that reverse worked just 10 minutes earlier when I left the junk yard. When I got it home 2 hours later, it backed up under it's own power. I let it cool down completely and took it for a test drive and it drove perfectly. I have a few theories or questions:
Kickdown rod: Can it be in such a position that it could take away reverse? I would assume that if the spring wasn't returning it all the way forward that it wouldn't have shifted from 1st to 2nd properly. I ask this because I am not using the Holley spring mount and I'm wondering if the wrong spring set up allows the kickdown to be partially activated.
Fluid: What fluid are you suppose to use after a rebuild and what fluid can't you use. Mercon V says it supercedes earlier fluids, but is that wrong?
Am I wrong to assume that if fluid was the problem that I would have had problems with 1st and 2nd?
Cooling: What are signs of hot fluid other than smelling it. Once again, assuming I would have problems with all gears if fluid was too hot.
My guess is that something is sticking in the valve body, but before I drop the pan and pull out the valve body, I want to make sure all other avenues are exhausted.
Alright I did a search and found these threads with no final resolution on each. My new 2013 has the whistling noise at high speeds (65+) and high winds. It's for sure not from the engine and coming from both the driver and passenger mirrors. I can hear it with either or both front windows down but not back windows. No whistle at idle or due to high RPMs. What is the Jetta TSB # or a fix for this issue.

I have a '96 Dodge Ram 1500. The only way I can describe the problem is when I go around 75, it feels like it loses power for a split second, then recovers. It will do this repeatedly, until I slow down a bit, then it won't do it at all. But once I speed up it will do it again. My first thought was the distributor/cap.
