So i recently installed a posi unit and new axles, everything went in fine, it works like it should, except i now get "wheel hop" off the line when i go to burn out the tires. both tires spin like they should, but one of them will bounce like crazy causing a violent vibration in the back end. i heard its pretty common in thirdgens, any idea how to stop it so i can do a smooth sweet burnout?
