To service and repair the drive pinion bearings for a 9.75 inch axle, the following tools are required: j 22536 pinion driver (J 22536), j 22912-01 split-plate bearing puller (J 22912-01), j 42176 universal driver handle - non-threaded (J 42176), 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 243/267 (J 45705), j 7818 inner bearing race installer (J 7818), and j 8092 universal drive handle - 3/4 in - 10 (J 8092). Start by elevating the vehicle then detach the Differential assembly and pinion yoke with the pinion oil seal followed by the thrust washer. You should place the j 22536 pinion driver at the base of the pinion before using the j 22536 with a hammer to drive out the pinion while continuously watching for it to escape the rear axle housing. The j 45703 and j 42176 tools extract first the pinion preload shims and inner Pinion Bearing cup and oil deflector; the outer Pinion Bearing cup removal requires the j 45705 and j 42176. A hydraulic press working with the j 22912-01 tool enables inner Pinion Bearing extraction after which you can remove the pinion position shim. To carry out installation begin by placing the oil deflector inside the inner pinion cup bore before installing the cup with j 45704 and j 8092. Use j 7818 and j 8092 for outer Pinion Bearing cup installation. Establish the optimum thicknesses for pinion position shim and pinion preload shim of the drive pinion before reinstalling the Differential assembly and distributing appropriate lubricant into the axle and lowering the vehicle.
