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). Transfer Case - If Equipped Fluid Level Check This fluid level can be checked by removing the filler plug.

If the level of the lubricant is more than 1/4" below the bottom of the filler hole while the vehicle is on level ground, enough lubricant should be added to bring the level to the bottom of the filler hole.
