The job starts with raising and supporting the vehicle when swapping out the rear axle housing cover and gasket on a 10.5 inch axle. Make sure to get rid of the old axle housing cover bolts, discard them, and replace with fresh ones only. Carefully remove the bolts, cover, and gasket, and get rid of any gasket bits from the rear axle housing or the cover. Following that, put the axle housing cover and gasket onto the rear axle, and fasten the new bolts until they're tightened to 40 n.m or 30 lb ft. When you have finished tightening the bolts, fill the rear drive axle with fluid and take away the support before lowering the vehicle.
