Symptom Chart
Condition | Actions |
---|---|
Driveline clunk - loud clunk when shifting from REVERSE to DRIVE | GO to Pinpoint Test A |
Driveline clunk — occurs as the vehicle starts to move forward following a stop | GO to Pinpoint Test B |
Grunting — normally associated with a shudder experienced during acceleration from a complete stop | GO to Pinpoint Test C |
Driveline vibration - occurs at cruising speeds | GO to Pinpoint Test D |
Pinpoint Tests
Normal Operation and Fault Conditions Halfshafts transmit rotary motion through constant velocity joints in a uniform manner. The outer CV joints use balls, have no length compensation and engage in the wheel hubs. The inner CV joints use balls, have length compensation, and are locked in to the differential by a snap-ring. The inner CV joints use balls, have length compensation, and are locked in to the differential by a snap-ring. Possible Sources

A1 CHECK THE HUB NUT TORQUE | ||||
Is the hub nut loose?
|
||||
A2 CHECK THE TORQUE ON SUSPENSION AND STEERING SYSTEM FASTENERS | ||||
Is the any of the suspension and steering fastener loose?
|
||||
A3 CHECK THE CONSTANT VELOCITY (CV) BOOTS AND JOINTS FOR WEAR OR DAMAGE | ||||
Was damage found?

Differential Seals
NOTICE: When installing shafts, do not allow splines to contact seals during installation or damage to the seals may occur.
Halfshaft seals are susceptible to the same types of damage as drive pinion seals if incorrectly installed. The seal bore must be clean and the lip handled carefully to avoid cutting or tearing it. The seal journal surface must be free of nicks, gouges and rough surface texture.
For information on differential seals,
REFER to: Rear Halfshaft Seal (205-02 Rear Drive Axle/Differential, Removal and Installation).

WARNING: Driving while distracted can result in loss of vehicle control, crash and injury. We strongly recommend that you use extreme caution when using any device that may take your focus off the road. Your primary responsibility is the safe operation of your vehicle. We recommend against the use of any hand-held device while driving and encourage the use of voice-operated systems when possible. Make sure you are aware of all applicable local laws that may affect the use of electronic devices while driving.
