How to replace the drive pinion bearings on an 8.6 Inch Axle on Chevrolet Express 1500?

First lift the vehicle and take out both the Differential assembly and the drive pinion from the axle before drive Pinion Bearing replacement on 8.6 inch axles. The split-plate bearing puller (J22912-01) enables removal of drive pinion bearings after which you need to take off the selective pinion shim. The outer Pinion Bearing cup must be extracted from the axle housing by using a hammer and brass drift while alternating sides during the removal process. You should execute the same steps once more to remove the inner Pinion Bearing cup. Install the specific parts with the rear Pinion Bearing race installer (J8611-01) along with the universal driver handle (J8092), then use the Pinion Bearing cup installer (J45870) and universal driver handle (J8092) for the other procedure. You should set a selected shim thickness which should go between the gear shoulder and the inner Pinion Bearing. Position the inner Pinion Bearing using the pinion cone and side bearing installer (J24433) to achieve cone contact with the pinion shim while pressing. The next procedure requires replacing the collapsible spacer with new ones while applying the correct axle lubricant on both pinion bearings. The installer tool extension housing oil pump/seal installer (J38694) brings in the new pinion oil seal as the outer Pinion Bearing enters the axle housing. The pinion installation in the axle housing requires new yoke sealant (GM P/N 12346004 or Canadian P/N 10953480) on the pinion yoke splines prior to positioning followed by a proper yoke alignment to the removal reference marks. Use a soft-faced hammer to install the pinion yoke onto the pinion shaft until a few threads become exposed before adding a new washer and pinion nut. Reusing the previous pinion nut is forbidden. Use the flange and pulley holding tool (J8614-01) to secure the pinion yoke and continuously tighten the pinion nut with tool support until the pinion end play reaches its entire range. A torque wrench with inch-pound measurements should be used to measure pinion rotating torque which should fall within 1.0 - 2.3 nm (10 - 20 inch lbs.) for secondhand bearings while new bearings should maintain a torque of 1.7 - 3.4 nm (15 - 30 inch lbs.). Expand the pinion nut tightening until you reach the recommended torque level when the initial measurement falls under the target range. Check the torque specification on the pinion once validated afterward you should rotate the pinion several times before rechecking the torque for potential adjustments. End with the Differential assembly reinstallation before you add the correct lubricant and let the vehicle lower.
