Begin the wheel drive shaft system diagnosis with Diagnostic Starting Point - Vibration Diagnosis and Correction . The use of the Diagnostic Starting Point will determine if the concern is wheel drive shaft related. When instructed to exit the Vibration Diagnosis and Correction diagnostic and return to the Diagnostic Starting Point - Wheel Drive Shafts, proceed to Wheel Drive Shafts Description and Operation in order to become familiar with the design of the wheel drive shaft.

The wheel drive shafts in this vehicle may not exhibit the same noise symptoms as wheel drive shafts in front wheel drive vehicles. Since the vehicle is a rear wheel drive design, the wheel drive shafts are not subjected to the same input forces and may not make any discernible noises if they are damaged. Thoroughly inspect the entire wheel drive shaft for visible damage, leaking joint seals, and missing seal clamps. Replace these components as necessary. Refer to Wheel Drive Shaft Inner Joint and Boot Replacement or Wheel Drive Shaft Outer Joint and Boot Replacement .

After the inspection reveals no visual signs of wear or damage, it may be necessary to manipulate the inner and outer constant velocity (CV) joints in order to detect internal damage. Any binding or impeded movement of the CV joints may indicate damage requiring repair or replacement.
