As the title said, when I goose it, shake, rattle, and roll. Anybody else having this problem? driveshaft maybe? gears? help please!

 

Probably wheel hop if you lowered it. You'll need LCA relocation brackets to get the geometry of the LCA's correct again. Although you still should check all the usual things like U-joints, etc. just to be on the safe side.

 

its wheel hop. some relocation brakets and a set of LCA's will fix the problem.

if you car is lowered then get a adj. panhard rod so you can recenter the rear of your car.
