Rotate the differential case 180-degrees and slide the pinion shaft out 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, taking care not to damage the O-rings in the axleshaft grooves during C-clip removal.

Begin by loosening the wheel lug nuts, then raise the rear of the vehicle and securely support it on jackstands. Remove the wheel and, if applicable, the brake drum or the caliper and disc.

For installation, raise the rear axle assembly into place and secure it with upper suspension arm-to-axle housing bolts and nuts. Install the coil or air springs and connect the lower suspension arms. Raise the axle housing to normal ride height, tighten the upper and lower suspension arm-to-axle housing nuts. If applicable, reattach the height sensor for air springs.
