How to replace the rear axle shaft on an 8.6 Inch Axle with Drum Brakes (NON-VSES) on GMC Sierra 3500 Classic?

You need to support and lift the vehicle before beginning the replacement of the rear Axle Shaft on an 8.6 inch axle with drum brakes (NON-VSES). Start by removing the rear cover together with its gasket and then proceed to unscrew the pinion shaft locking bolt. The pinion shaft removal process varies between axles with conventional locking differentials since you need to pull the shaft partly out then turn the case with the pinion touching the housing. A screwdriver should be used to rotate the lock in the Differential case until it sits correctly against the thrust block. When removing the Brake Drum, push the Axle Shaft flange toward the Differential until the c-lock tool can be extracted from the Axle Shaft button without rotating the shaft to prevent gear misalignment. After setting the Axle Shaft inside the housing you must remove it. To install the Axle Shaft properly insert it into the rear axle housing while letting the splines connect to the Differential side gear. The c-lock should rest on the button end of an Axle Shaft without a locking Differential but should stay off the pinion shaft for axles equipped with this Differential. Drive the Brake Drum onto its position before setting the c-lock onto the Axle Shaft with both ends aligning with the thrust block . Pull the shaft flange away from you to secure the lock into the Differential gear while positioning the hole from the pinion shaft above the Differential case bolt hole. Put on the new pinion shaft locking bolt before tightening it to 34 n.m (25 lb ft). Afterward install the rear cover and gasket then proceed with tire and wheel assembly and fluid addition into the rear axle before lowering the vehicle.
