i have searched and found answers but still not sure what it is

this just started all of a sudden, not slowly over time.....i get a bad vibration when i am accelerating and at speed......it stops if i push the clutch in or let off the gas while i am cruising or accelerating. It is speed dependent not engine rpm....i checked the driveshaft, mounts, and cv joints today and all seem fine

i dont understand how it could just start all of a sudden.....i just took off from a stoplight and was like wtf?????/

it gets worse the harder i accelerate.....the vibration is felt in the seat and really the whole cabin.....the shifter rattles alittle but not much

any help is appreciated...thanks alot

check your clutch fan. i had the same problem and i couldnt figure out why i was getting a vibration then one day i put on new a clutch fan and the vibe went away. i dont know if this is your problem but its somthing to check
it could be a missfire at high speed though unlikly

 

Sounds like a front mount on your diff. It's trying to spin backward as the tires spin forward, lifts into the body. Double check it.

 

did you check the driveshaft u-joints?

 

i got under the car today again...with a jack this time.....the front u joint is out....i dont know how i missed it yesterday....
thanks all
