I noticed not too long ago that when i accelerate there is a bad vibration in the rear of my car. Also, under acceleration, the car pulls slightly to the passenger side. However, when coasting (not touching the gas) the car stays perfectly straight. I am taking the S on a road trip in a month and want to get this straightened out before hand. Has anyone experienced a problem similar to this. I believe the problem probably has to deal with the half-shafts, however this is something that i am very unfamiliar with.

thank you very much.

 

Vibration under accel only=bad CV drive buckets. you can swap them side to side and be good as new.

Car pulls on accel=uneven rear tire pressure from side to side

 

you can also correct the problem with the halfshaft spacers

 

okay, ill put some spacers in and see what happens.
