I took my car to the track last sunday and when the car leaves I had a real bad wheel hopping problem. After I left the track driving the car home there was a very bad vibration coming from the rear of the car. It only happens around 30 mph up to about 70 mph....Any help would be great..... I have checked the drive shaft it looks ok. PLEASE HELP

wheel hop is caused by the lower control arm bushings being worn out.
and if you completely screwed them up, id say thats your problem

Do you think that the LCA bushings is what is causing the vibraton??

if thats not it, i could see maybe a axle bent from the hopping but that may be a stretch.
that or driveshaft.
i really doubt that its a tire that through a weight but guess that also could be a option

Mine did that and it spun the wheels inside the tire, this threw the tire balance completely off. I chased it for weeks. Balanced the rear tires, fixed.

i had a tire spin but it broke the bead and lost air pressure

narrowed the problem down to the drivetrain. Replaced u-joints and bushing in tailshaft, pulled out the axles and checked them, and also checked the motor mounts. The vibration is felt at too low of a speed to be the tires out of balance. Any more suggestions? The vibration is felt in low rpm's all the way up to higher rpms's.
