clunk noise originating from the underside of the vehicle upon acceleration.
This may be caused by a loss of clamp load at the joint that attaches the propshaft to the transfer case.
Correction
If you encounter a vehicle with the above concern, complete the following procedure:
- Raise and support the vehicle.
- With the vehicle in the air, visually inspect the propeller shaft CV joint to transfer case flange bolts for looseness.
- If any of the bolts are loose, continue to Step 3.
- If all the bolts look secure, continue with diagnosis referring to Service Information.
- If one or more of the bolts are visually loose, replace all six of the propeller shaft CV joint to transfer case flange bolts.
- When replacing the bolts, be sure to install and tighten in sequence (1–6) to 40 Nm (29 lb ft) as illustrated above.
