Carrier Cover

To replace the Differential carrier cover and seal on the left-hand side, raise the vehicle and adequately support it. Dismount the lh rear tire and wheel assembly 02100-020-lh wheel drive shaft and the lh Muffler assembly 02020-020-lh tire wheel wells muffle duct. Drain the fluid from the Differential, then raise the Differential, then remove the left Differential mount. Clean around it of any dirt or debris and then take out the two bolts that hold the Differential cover in place and push out the dowel pin. Carefully remove the Differential cover and make sure the magnet at the bottom of the Differential case is not thrown away. Remove the o-ring seal as well as the axle seal from the Differential side cover. For installation, clean the o-ring sealing surface on the Differential cover and the Differential housing, and fix a new o-ring seal on the Differential cover. Mount the Differential cover onto the Differential, put the dowel pin and the two bolts for Differential cover retaining at work, tightening them 28 n.m (20 lb ft). Tight up the bolt containing the left Differential mount to 50 n.m (37 lb ft). Since the axle seal was successfully installed using a j 46405 output shaft seal installer, install the axle seal into the Differential cover. Add the appropriate fluids into the Differential up to the right level, then reinstall the lh Muffler assembly, the lh wheel drive shaft, and the lh rear tire and wheel assembly before lowering the vehicle.
