In replacing the rear axle housing cover and gasket, one should begin by lifting and draining the rear axle as is appropriate for the type of rear axle one would be using to get started (8.6 Inch Axle, 9.5 Inch LD Axle, 10.5 Inch Axle). Next, remove the rear axle housing cover bolts and discard them and then remove the rear axle housing cover off the axle housing, taking care to catch any oil using a drain pan and to remove any gasket material from both rear axle housing and the cover. For replacement, install the new gasket and rear axle housing cover and ensure that you do not reuse the rear axle housing cover bolts. Replace new rear axle housing cover bolts and install them in a crosswise pattern at a torque of 40 n.m (30 lb ft). Lastly, in filling the rear axle, use the appropriate fluid and drop the vehicle.
