MAINTAINING YOUR VEHICLE 369 Clutch Hydraulic System The clutch hydraulic system is a sealed maintenance-free system. In the event of leakage or other malfunction, the system must be replaced. Rear Axle And 4x4 Front Driving Axle Fluid Level For Model 9.25 Front Axles and 10.5"/11.5" Rear Axles refer to Recommended Fluids, Lubricants and Genuine Parts for the correct lubricant type. For normal service, periodic fluid level checks are not required. When the vehicle is serviced for other reasons, the exterior surfaces of the axle assembly should be inspected. When checking the fluid level, the vehicle should be in a level position. The fluid level should be 1/4" ± 1/4" (6.4 mm ± 6.4 mm) below the fill hole on the 9.25" Front Axle. The fluid level should be 3/4" ± 1/4" (19 mm ± 6.4 mm) below the fill hole on all 10.5" and 1/4" ± 1/4" (6.4 mm ± 6.4 mm) on 11.5" Rear Axles. Drain And Refill Vehicles operated in normal service do not have regularly scheduled oil changes. If fluid has become contaminated with water or subjected to severe service, follow the recommended change intervals in Maintenance Schedule "B" in Section 8 of this manual. Lubricant Selection Refer to Recommended Fluids, Lubricants and Genuine Parts for the correct lubricant type. 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. Limited-Slip Differentials in vehicles equipped with 10.5"/11.5" Axles DO NOT REQUIRE any limited slip oil additive (friction modifiers). 7
