Started happening lately. When I accelerate hard it's starts to have this very LOUD cracking/clicking/rattling sound from the rear. Only happens under tension from the drivetrain when the power is applied. What could it be? Haven't a been under yet.

 

So right now I'm experiencing one of my gas struts that is connected to the hatch is loose where the bushing is on the mounting point. Try that and it's easy to diagnose.

 

Wheels bearing or cv joint would be my guess. Much like the FWD cars get when they turn and the CV joint is worn.

 

Thanks to both of you. The culprit is a worn/destroyed driver side rear cv joint.
