2. This bulletin applies to vehicles within the following markets/countries: North America, LATAM, APAC and EMEA.

3. Proper maintenance at the required intervals will greatly reduce the potential for premature double cardan joint failure

DISCUSSION:
The joint must be lubricated with a Needle Nose Grease Gun Adapter during scheduled maintenance every 12874 km (8000 miles) (gas engine) or 12070 km (7500 miles) (diesel engine). 


                              


Lubricate the double cardan joint per the maintenance schedule using MOPAR type MS6560 lithium based grease or an equivalent. Lubrication requirements are detailed in service information and the owners manual. There is an under hood reminder sticker on the left front fender.


                


The double cardan joint is equipped with a low profile needle point grease fitting. The needle point greasing adapter tool is included in the MOPAR Express Lane tool kit and also readily available through other tool providers. Inspect the double cardan joint near the transfer case front output shaft during service. Check for signs of distress include gaps in the bearing area and rusty powder on the yoke surfaces and repair as necessary.
