Rear Drive Halfshafts. Diagnosis and Testing

Preliminary Inspection

Visually inspect the CV joints, housing, boots, and clamps for obvious signs of mechanical damage.
If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
If the cause is not visually evident, verify the symptom and REFER to Symptom Chart: NVH.
