When moving in reverse or drive, from a stop, the rear end makes a loud popping sound. (thought my spare tire had come loose. Verified that was not the case) while driving on a roadway and turning corners, you can feel the rear end sway as if the axle shafts are too long which causes the rear end to feel loose. Effects driveability.
