MY question is what causes wheel hop? I noticed after I put my new rearend in that i've been getting massive amounts of wheel hop almost everytime i break the tires loose. The car is in need of shocks and I was wondering if that would be what causes the wheel hop

 

that can definatly cause it

also check to make sure your bushings are in good shape and the bolts are tight.

sounds like it's time for some suspension upgrades
