Chevrolet 7846871 AXLE KIT

To remove the rear axle, start by removing the rear springs and disconnecting the brake lines from the control arm attachment. Disconnect and cap rigid brake lines from both rear brake cylinders and disconnect the right rear parking brake cable from the left rear parking brake cable. Next, disconnect the right rear and left rear parking brake cables from their brackets on the rear axle. Remove bolts securing the rear parking brake cable guide to underbody and allow whole parking brake assembly to hang loose from right rear backing plate. Remove bolts securing hub and bearing assembly to rear axle; remove assemblies with brake backing plates. With another person's help, steady jack under the rear axle and remove bolts that secure control arm brackets to body. Lower, pull out of underneath car. In case of replacing a new axle again, remove control arm brackets from control arms and install them on new axle. Inspect control arm bushings for any damage necessary. Before installing make sure that lower edge of control arms is true horizontal plain and adjust control arm brackets to 45° angle if required. Reverse order of removal in installing rear axel ensuring not to tighten lower shock nuts or track arm nuts until car is lowered onto suspension with its full weight on it. Finally, bleed the brakes system as usual then adjust parking Brake.

To start replacing the axle shaft components, you need to detach it from the vehicle. Carefully knock off the outer joint seal retainer from around the joint assembly by tapping evenly all the way round it and severing the seal retaining clamp with a hacksaw blade. The joint assembly is removed from the axle shaft by spreading apart the retaining ring with snap ring pliers. Take off the axle shaft's outer joint seal as well as its seal retainer. To remove ball bearings, softly tap on bearing cage for rotation within outer race. Pivot cage and inner race that aligns windows of cage with lands of outer race are lifted out after balls have been removed. Withdraw inner race by rotating it within cage. Using this method, take out the inner joint assembly, seal retainer, inner joint seal and seal retaining clamp right from the axle shaft. Clean all pieces in solvent; keep separate inner and outer joint assembly parts. Assess races, cages and ball bearings for any damage that may call for replacement. Check condition of rubber seal boots for any holes or cracks; if necessary put in new ones only then apply lithium-based grease into them then begin reassembling parts again. Put back balls and pack grease into joints before applying a new hose clamp or seal retaining clamp onto axle shaft followed by a seal retainer and finally an inner joint assembly's sealing point at doorways to avoid leakages which can be course by looseness during driving. These seals must be tightened to their grooves using clamps in order to adjust them until they fit properly thereby preventing further leakage through these joints in future when driving after installation. Finally follow these steps once more but now installing outer one on other side so do not forget about slide it over shaft while pressing other end of assemble until retaining ring will pop up back into place along entire length. At last reinstall axle shaft into vehicle.

For 1974-1977 models (excluding axle codes 'B' and 'O') and 1978-1980 models (excluding 'B'), follow these steps, Raise the vehicle's rear and remove the wheel and brake drum. Take off the differential carrier cover, draining the oil. Remove the lock screw and pinion shaft. Push in the axleshaft's outer end, remove the C-ring, and carefully extract the axleshaft, avoiding oil seal damage. For reinstallation, reverse the steps, ensuring correct torque for the lock screw and cover bolts. Replace the cover gasket and refill with the appropriate lubricant.

GL-5 hypoid-type gear oil such as SAE 80W or SAE 80W/90.
