Service
1. Inspect the rear inner CV joints where they connect to the rear sports differential:
• Oil sweating or residue – do not make any repairs.
• Clear oil drips – proceed to step 2.
2. Determine source of the fluid:
• Grease used in the drive shaft CV joints is almost odorless. If the fluid does not have any odor,
proceed to step 3.
• Differential fluid has a pungent smell. If the fluid has a pungent smell, this TSB does not apply.
