Vibration When Accelerating

I have a really bad vibration when i accelerate. it usually does it 1st and second gear from 2-3k rpms. i have no idea where to begin my search. I know the driveline ujoints are good because i just replaced the clutch. I was thinking axle bearings but then the vibration would happen all the time right?

    No...because before i put the new clutch in it would do the same thing and this is the first time the clutch has been replaced.

  • bmxjsh6 Jan 26, 2009

    if the old clutch was worn into the flywheel why would it vibrate then? and why would it only do it in 1st and 2nd? just asking Thanks

    Did you put any stress on the input shaft when you refitted the gearbox ?

Did you machine the flywheel? Because if you replace the clutch without machining the flywheel. The flywheel will have high and low spots on it. The new clutch is perfectly flat, and the old clutch was worn into the flywheel. Thus, vibration! I sincerely hope that I helped. Best wishes to ya.

    The old clutch was worn into the flywheel like brake pads wear into rotors, but you still get a pulsation from the warped rotors when applying the brakes. High and low spots can wear into the clutch horizontally, but cannot wear in vertically. Imagine a record player:

    there are horizontal lines on the record right? The needle follows them perfectly, but what happens when you put a scratch from the center outwards? The needle bounces over the scratch. And it does it on first and second because those are your initial take of gears, where you feel the most of the clutch gripping onto the flywheel. The upper gears are kind of soft shifts. Not alot of torque there. I hope that this answers your questions. God bless.

    If this fixes you up, could you change the rating to fixya for me? I think you can write them or something like that to change it. If so, Thank You!!!

depending on where the vibration is from, either the tyres (could be a buckled rim, (jack it up and spin the wheel by hand and check) or it could be a drive shaft problem. It could be a bent shaft or worn knuckle. It would be better if I knew if you meant vibration or wobble and also where about in the vehicle you feel it most.

Have you checked your oil and fluid levels in the engine and transmisson.
if it's a manual could the clutch be worn out causing the high rpm and thrust bearing noise in the clutch.

2004 Dodge Dakota - vibration when accelerating from stop. Even happens when in neutral and I slowly accelerate.


if the vibration increases as you accelerate and change through the gears you could possibly have a universal joint on half shaft that is worn beyond its limits.If it only vibrates as a the motor increases the rpms it could be that your harmonic balancer this damaged all worn out.There is another possibility and that is that you have a damaged tyre that goes out of balance very quickly.

I have a 1998 GMC Sierra, 5.7 liter Vortec 4x4. It has 160k miles. I have noticed that it idles at around 500 rpms when its warmed up. Not sure if this is normal. However, I have noticed a bit more...


The normal idle for your engine should be 550 to 600 RPMS so thats not to far off . But the fluctuation is more likely the crank pisition sensor then the EGR valve this engine has a condution called crankshaft wip witch is normal but going down a rough road can somethimes set off a misfire code It wouldn't be a bad idea to take the EGR valve off and clean it and check it but the CPK would give you the fluctuation in RPMS . It still could be a few outer things but this it the most likely cause

sounds like 3rd gear/clutch is worn.I don't think a service will do any good.But if you remove the pan and find debris you know you will need a trans in the near future.

Pick up seems to drag/vibrate esp at 1st gear even though the ff. have been replaced: release bearing, clutch disk, pressure plate, transmission support, center bearing and cross joints. gear oil are all...


My 96 Nissan 4x4 did this especially in first and in second as well if accelerating hard and also more pronounced if hauling heavy items. It turned out that the front yoke on the driveshaft linking the transfer case with the front differential was rusted and frozen to the portion of the driveshaft on which it is supposed to slide. If your truck is not four-wheel-drive this will not be the cause of your vibration. If your truck is 4x4 and this is the cause of your vibration and it has been doing it for a while, check your engine mounts as the vibration can damage/break them--especially the left one.

I've got an 08 4cyl and it doesn't really have the vibration unless its really cold. Usually if I give it about 30 seconds...when the rpms start to come down, its barely noticeable.
