GMC Envoy Pinion Bearing Parts Questions & Experts Answers
Q: How to replace the drive pinion bearings in the rear drive axle on GMC Envoy?
A: The process of swapping drive pinion bearings in rear drive axles starts with vehicle elevation and Differential and drive pinion removal from the axle. The split-plate bearing puller (J 22912-01) should be used to push off the bearing which sits on the pinion before you can remove the shim. When extracting bearings from the axle housing work evenly with a hammer against a brass drift to remove the outer cup followed by the inner cup extraction. The installation of the outer Pinion Bearing cup requires an outer bearing race installer (J 7817) and universal driver handle (J 8092) while the installation of the inner Pinion Bearing cup needs a rear Pinion Bearing race installer (J 8608) with the universal driver handle (J 8092). Insert the selective shim of the chosen thickness between the inner Pinion Bearing and gear shoulder. Execute the inner Pinion Bearing installation with pinion cone and side bearing installer j 24433 while pushing it down until the cone completely seats onto the pinion shim. The installation process requires a new collapsible spacer with proper axle lubricant application to the pinion bearings. Place the axle housing pinion next to the outside bearing before adding both components. The pinion oil seal installer (J 33782) must be used for new pinion oil seal installation before applying gm p/n 12346004 (Canadian P/N 10953480) sealant to the pinion yoke splines and placing the yoke in position. Finally, match attaining alignment along the original marks. Drive the pinion yoke onto the pinion shaft using a soft-faced hammer until it shows a few threads. Subsequently add the washer and brand-new pinion nut. Using the holding tool (J 8614-01) on the pinion yoke secure it while tightening the pinion nut until the end play reaches its minimal point. A mechanic should use an inch-pound torque wrench to measure pinion rotating torque at 1.0 to 2.8 nm (10 to 25 inch lbs.) for used bearings or 1.7 to 3.4 nm (15 to 30 inch lbs.) for new bearings. Tighten the pinion nut by small amounts until its rotating torque matches the specified range. Use the torque meter to check the specified value before rotating the pinion at least three times to check bearing seating. Make additional adjustments if required. The vehicle requires reinstallation of its Differential before lubricating the axle with proper fluid then proceeding to lower the vehicle.
