Hi i have a 1997 audi A4 2.8 quattro manual and im having troubles figuring out whats wrong with my car. Just recently it start to act up im feeling Vibrations as i rest the car in gear and cruise normal,, however if i accelerate it goes away slightly.

Note: i have just change both suspension in the rear also my back brakes the slide for the brake tends to sees up when i leave the ebrake on for a long time im in the process of lubing and cleaning it.

Would appreciation some comment i miss how it use to ride so smooth

 

I would check the front inner c/v joints for any wear. Just remember even if the boots are in good shape the joints can be worn.

 

I just remember when i changed the suspension at the back i didn't get new mounts i used the original ones and the old suspend was warp not even strait could this be a possibility. I believe its coming from the rear

 

Is the vibration coming from the back or the front?
Do you feel it it your hands or your back side?

 

on teh back no vibrations on the steering wheel i feel it on teh back of my seat and its stating to get worse esically when im accelerating on gear 3

 

Sorry its hard to tell but its going through out teh car and it feels like its struggling

 

YOu could possible need new mounts? Dont know but its something too look into
