2009 Chevrolet Tahoe Differential Mount

You need to install the lower differential carrier assembly bushing by installing the J 21474-18, the thrust bearing, the J 36616-2, the J 36616-1, and the forcing screw. While holding the forcing screw, slowly tighten the J 21474-18 until the bushing has stopped against the step on the bushing and is centered within the differential carrier assembly bushing bore. Next, you can install the upper differential carrier assembly bushing by performing the following steps: install the J 21474-18, the thrust bearing, the J 36616-2, the J 36616-1, and the forcing screw as shown. While holding the forcing screw, slowly tighten the J 21474-18 until the bushing has stopped against the step on the bushing and is centered within the differential carrier assembly bushing bore. Then you can install the differential carrier assembly.

You need to remove the differential carrier assembly and the upper differential carrier assembly bushing by performing the following steps: Install the J 36616-2, the J 33791-1, the thrust bearing, the J 21474-18, and the forcing screw as shown. Next, you can remove the upper differential carrier assembly bushing by holding the forcing screw and slowly tightening the J 21474-18 and remove the lower differential carrier assembly bushing by performing the following steps: Install the J 21474-18, the thrust bearing, the J 33791-1, the J 36616-2, and the forcing screw as shown, and remove the lower differential carrier assembly bushing by holding the forcing screw and slowly tightening the J 21474-18.
