so 2 days ago my car was fine other than i need new brakes and they are squealing at me but today i took off and the car is bumpy or vibrating only when i accelerate any ideas? i checked the wheels they are all tight and revved the engine from the front and the engine sounds fine and didnt seem too move much and there are no new engine codes :/

 

Vibration on acceleration is pitted rear CV buckets on the axles.

Remove axles and swap buckets left to right, will be good as new. No new parts to buy at all.

 

^^ is there a DIY for this?

 

Yes there is. google DIY CV buckets s2ki

 

so i googled what you said to and nothing came up is there another name than buckets? and i hope thats all it is no money fix would be great and what causes the problem exactly?

I think that might be what you are looking for?

 

oh ok thanks

 

to add to this thread,
I have the same vibration issue,
but it happens right around when I start passing 58mph.
it doesnt seem to get worse after that-
it just vibrates from that speed and on, only subtly flucuating more or less.
does it in neutral and when in gear
it also does it when accelerating or coasting

recent changes include:
went back to stock
changed out a diff for a new one.
changed out axles for other ones
changed out the v160 tranny back to a stock used one
changed out an af exhaust and test pipe back to stock exhaust and cat
went from flat roads in miami to bumpy and hard roads in Michigan (prone to rim bending ??)

engine seems fine and so does the rest of driving.

Its kind of broad, I know, but what are some things it could be? (process of elimination)

 

Maybe the engine, trans, and diff mounts?

 

BrockB, your problem is in the driveshaft, wheels, or tires.
