My '96 Cruiser with standard OME springs and shocks has too much play in the rear axle. When I drive over speed bumps or enter/exit my driveway, the rear axle wobbles and clunks little bit and it seems like something is loose. The front axle is very tight. I've looked at the control arms, the springs, the shocks, the panhard rod, and the bushings. Everything looks fine. Is this normal? Any suggestions for a fix?
