When I drive over a ruff or bumpy road my rear end bounces up, and is all over the road. It hopp's up even more when accelerating, The tires wont keep contact with the road. What part of the rear suspension is the problem, shocks, spring, or is the control arms. Have any of you guys had this problem? How do you fix it? I'm thinking control arms will fix it becuse it seems like wheel hop, but I'm not sure. Maybe it needs new shocks?
