To replace the drive pinion bearings on 9.75 inch and 10.5 inch axles, the following tools are required: j 22536 pinion driver (J 22536), j 22912-b split-plate bearing puller (J 22912-B), j 42176 universal driver handle - non-threaded (J 42176), j 44417 rear Pinion Bearing race installer (J 44417), j 45703 Pinion Bearing race remover - dana 248 (J 45703), j 45704 Pinion Bearing race installer - dana 248 (J 45704), j 45705 Pinion Bearing race remover - dana 248/267 (J 45705), j 45706 Pinion Bearing race remover - dana 286 (J 45706), j 7818 inner bearing race installer (J 7818), and j 8092 universal drive handle - 3/4 in - 10 (J 8092). Start the procedure by lifting the car then unfastening the Differential components one by one beginning with pinion yoke followed by oil seal then thrust washer. Secure the j 22536 onto the pinion while ensuring its complete seat. Next, drive the pinion outward by using j 22536 and a hammer with care for preventing pinion exit from the rear axle housing. Drawable the pinion preload shims and both axles with the pinion spacer (10.5 inch axle only) from drive pinion assembly before setting them aside. To remove the inner Pinion Bearing cup and oil deflector of both axle types use j 45703 (9.75 inch axle) or j 45706 (10.5 inch axle) together with j 42176. The operator can remove the outer Pinion Bearing cup with a combination of the j 45705 and the j 42176. The selective pinion shim should be extracted first followed by the inner Pinion Bearing removal with j 22912-b along with hydraulic equipment. To install both inner and outer Pinion Bearing cups first select the j 45704 with j 8092 when dealing with a 9.75 inch axle or j 44417 with j 8092 for a 10.5 inch axle then set up the j 7818 with j 8092 for the bearing cup installation. Selectively adjust the thickness of the selective pinion shim as well as the pinion preload shim for the drive pinion before reassembling the Differential and lubricating the axle properly. Finally, lower the vehicle.
