Question 1

What tools are required to service and repair the drive pinion bearings for a 9.75 inch axle on Chevrolet Blazer?

Accepted Answer

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.

Question 2

How to replace the drive pinion bearings on a 10.5 inch axle on Chevrolet Blazer?

Accepted Answer

The tools required to replace drive pinion bearings on a 10.5 inch axle consist of j 22388 (Pinion Oil Seal Installer-Rear), j 22761 (Differential Side Bearing Installer), j 22912-01 (Split Plate Bearing Puller), j 24433 (Pinion Cone and Side Bearing Installer), j 37624 (Pinion Bearing Installer), j 8092 (Universal Driver Handle - 3/4 in - 10), j 8608 (Rear Pinion Bearing Installer), and j 8614-01 (Flange and Pulley Holding Tool). Workers should first elevate the vehicle before taking out the Differential unit followed by the pinion gear bearing retainer, pinion yoke, oil seal, and outer Pinion Bearing. Enso and collapsible spacer must be removed before the j 22912-01 and hydraulic press extract the inner Pinion Bearing. A hammer along with a brass drift should be used to eliminate both the outer and inner Pinion Bearing cups. The procedure for installing pinion gear pilot bearing requires the j 22761 tool followed by an installation sequence of the inner Pinion Bearing cup using j 37624 and j 8092 then the outer Pinion Bearing cup needs to be installed with j 8608 and j 8092. After installing the inner Pinion Bearing with j 24433 you should add a new collapsible spacer before lubricating the pinion bearings. Feed the outer Pinion Bearing into the retainer and mount a fresh pinion oil seal by using j 22388 before inserting the pinion into its bearing retainer. Warm the pinion yoke splines before applying sealant. Install the yoke afterward and correctly attach it to the pinion shaft by using a soft-faced hammer. Tighten the new pinion nut under j 8614-01 tool torque until the pinion end play reaches its maximum resistance. Place the original shim or a 0.41 mm (0.016 inch) alternative shim when you need to replace the missing j 8614-01. Install the pinion gear bearing retainer onto the axle housing before fastening its bolts to 88 nm (65 ft. Lbs.). The measurement of rotating torque for used pinion bearings should fall within 1.0 to 2.3 nm (10 to 20 inch lbs.) while new pinion bearings should measure between 1.7 to 3.4 nm (15 to 30 inch lbs.). You should use the j 8614-01 torque wrench to increase pinion nut tightening steps until reaching the required specification torque. Rotating the pinion several times following torque confirmation helps bear in a proper position but rechecking the torque might be necessary for adjustment. To complete the task you must restore the Differential assembly while adjusting the side bearing preload and selecting drive pinion shims and adjusting backlash before filling with lubricant and returning the vehicle to the ground.
