CONDITION SUMMARY:
SITUATION:
An issue has been identified on certain vehicles within the listed Affected Vehicle Range which have
had a transfer case replacement and, as a result of an incorrect instruction in the Workshop Manual,
may have had the incorrect torque applied to secure the torsional damper.
ACTION:
Retailers are required to HOLD affected new vehicles that are within your control and refrain from
releasing the vehicles for new vehicle sale pending completion of the Workshop Procedure detailed in
this Technical Bulletin. Unsold vehicles should have this performed as part of the Pre-Delivery
Inspection (PDI) process but must have it completed prior to vehicle handover to the customer.
Affected vehicles already in the hands of customers should be updated at the next available
opportunity.
