Got a VIBRATION
 

After going to the track i notice my car was vibrating. Not to bad ,but enough to notice it. I have a aluminum drive shaft. That helped elimanate my vibration to begin with. Now it is back just not as bad. Do you have any idea what it could be.

If it has a stock balancer I would be checking it for cracks and weather it tried to spit the ring off of it.

brake drums
pinion bearing
pilot bearing
gears
A-arm bushings

it has a new balancer. And it has a new pinion bearing. All new rear brakes and drums. The a arm bushings may be the problem cause they are pretty much shot guess i'll look at that

u joints

i would say ujoints also.
