Remove the rear axle cover and drain the lubricant.

Loosen the wheel lug nuts, raise the rear of the vehicle, support it securely on jackstands and remove the wheel. Also remove the brake drum, or the caliper and disc. Remove the cover from the differential carrier and allow the lubricant to drain into a container. Remove the lock bolt from the differential pinion shaft. Slide the notched end of the pinion shaft out of the differential case as far as it will go. Position a large screwdriver between the rear axle case and a ring gear bolt to keep the differential case from turning when removing the pinion shaft lock bolt. Rotate the differential case 180- degrees and slide the pinion shaft out of the case until the stepped part of the shaft contacts the ring gear. Push the outer (flanged) end of the axleshaft in and remove the C-lock from the inner end of the shaft. Take care to not damage the O-rings in the axleshaft grooves when removing the C-clips. Withdraw the axleshaft, taking care not to damage the oil seal in the end of the axle housing as the splined end of the axleshaft passes through it. Do not rotate the differential while the pinion shaft is out, or the pinion gears could fall out. Installation is the reverse of removal. Tighten the differential pinion shaft lock bolt to the torque. Install the differential cover. Refill the axle with the correct quantity and grade of lubricant.
