SYMPTOM/CONDITION

Click/snap/clunk from the rear axle when engine torque is applied during acceleration or when shifting from forward to reverse.

DIAGNOSIS

Road test the car with several deep throttle accelerations from a standing start. If there is a snap/click/clunk noise coming from the rear axle area, it may be caused by excessive clearance between the rear axle inner bearing and the bearing spacer. See Figure 1.
