Message I'm recently getting excessive wheel hop under normal load, usually from stop and go at a light, and slightly from 1st to 2nd. I'm not punching it, just normal city driving and it's getting super annoying and everybody looks at me like a freak (especially last night at the up-hill border lineups).

I've had this issue for a while now, but it was only after when the car was parked for an extended period, and it would be gone after a few stop and go's.

Once I changed to a 5 puck, a vibration formed in my drivetrain. Knowing that my driveshaft was on it's way out, I purchased a new one, which changed nothing.

I then changed the diff bushings and added subframe spacers, which actually AMPLIFIED the hopping to a point that I feel my diff is going to blow up or pop out or something.

I'm confused. There does not need to be any load for the wheels to hop as well. While on a hoist, in gear, and at ~2200rpm, the wheels start to hop in the air.

What could cause this? My diff does have a bit of lash, and my input shaft has a *little* play...but that's all I can really think of. Could it be another bushing that I just don't see and/or don't know about?
