248 MAINTAINING YOUR VEHICLE Transfer Case Inspect the transfer case for fluid leaks. If a fluid leak is evident the transfer case fluid level can be checked by removing the filler plug located on the back side of the transfer case. The fluid level should be at the bottom edge of the filler plug hole when the vehicle is in a level position. The transfer case fluid should be drained and refilled at the intervals specified. Lubricant Selection Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. Axles Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. The manufacturer does not recommend regularly scheduled oil changes for axles in vehicles whose operation is classified as normal truck service. NOTE: The presence of water in the gear lubricant will result in corrosion and possible failure of differential components. Operation of the vehicle in water, as may be encountered in some off-highway types of service, will require draining and refilling the axle to avoid damage. Rear Axle Limited-slip differentials require the use of Mopar limited slip additive. Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. This should be added to the gear lubricant whenever a fluid change is made, when equipped with a limited-slip differential. Rear axle fluid level should be 1/4 (6.35 mm) below filler plug hole for 8 1/4 axles and should be 5/8 (16 mm) below filler plug hole for 9 1/4 axles. Front Axle Front axle fluid level should be at the bottom of the filler plug hole. Selection of Lubricating Grease The National Lubricating Grease Institute (NLGI) has developed a symbol (Certification Mark) to aid the vehicle owner in the proper selection of grease for chassis components. This symbol, an example shown below, is located on the grease container and identifies the application and quality of the grease.
