My car rocks uncontrollably when hitting bumps...is it axle issues or motor mount issues and how much is that gonna cost me?

check your shockies
push on vehicle above each shockie hard half a dozen timesso the vehicle is bouncing then stop abruptly vehicle should stop moving after 1 or 2 bounces if not the shockies should be replaced
