so my car started vibrating out of nowhere. once i hit about 45-50mph the front end starts to vibrate, and persists until about 80mph, after that it doesnt seem too noticeable. the thing is it only vibrates under accelleration, if i let off the gas the vibrating stops. any ideas?

 

check your motor mounts.

 

how do i go about checking to see if they are bad? i'm thinking it's the rear mount..

thanks for the help

what i did was. i use my bare hand to shake on the engine and see if it moves a bit. and to check out which one is bad. i had to use my friend's hydro car lift at his work shop. we lisfted the car up and placed a 2 by 4 long wood underneath each motor mount and slow lowered the car a bit and see if there is any crack or damage on the mount

 

sounds like a axle problem to me check your u joints or whatever they are called on your axle

 

i just use my shifter as a reference. When I floor it I measure how far it moves, and in what direction- in gear.

I highly suggest prothane or es motor mounts. best upgrade possible for the money.
