REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Loosen the rear wheel lug nuts.
- Raise and safely support the rear of the vehicle securely on jackstands.
- Remove the rear wheels.
- On models with rear disc brakes, remove the caliper and brake disc.
- On models with rear drum brakes, remove the brake drum.
Check the bearing backlash and axle hub deviation.
- Place a dial indicator near the center of the axle hub and check the backlash in the bearing shaft direction. Maximum is 0.0020 inch (0.05mm). If the backlash exceeds the maximum, replace the axle hub with bearing.
Using a dial indicator, check the deviation at the surface of the axle hub outside the hub bolt. Maximum deviation is 0.0028 inch (0.07mm). If the deviation exceeds maximum, replace the axle hub with bearing.
- Remove the 4 bolts and rear axle. The bolts are accessed through the hole provided in the hub. Turn the hub to access each one of the bolts.
- Pull the hub off and remove the O-ring on the back of the unit.
- Coat the O-ring with MP grease and insert into the back of the hub.
- On models with drum brakes, remove the brake hose from the shock.
- Disconnect the backing plate from the rear axle carrier. Support the backing plate securely.
- On models with ABS, remove the speed sensor.
- Remove the nut and bolt, the disconnect the strut trod from the rear axle carrier. Remove the 2 nuts from the shock lower set bolts, but do not remove the bolts.
- Disconnect the lower suspension arms from the axle carrier. Pull out the 2 bolts from the shock and remove the rear axle carrier.
- Attach the carrier to the shock absorber. Attach the lower control arms to the axle carrier. Bounce the vehicle up and down several times and tighten the suspension arms B to 145 ft. lbs. (197 Nm).
- Install the shock absorber lower set bolts nuts, bounce the vehicle up and down and tighten the nuts A to 188 ft. lbs. (255 Nm).
- Attach the strut rod to the rear axle carrier, stabilize the suspension and tighten the nut and bolt to 83 ft. lbs. (113 Nm).
- On models with ABS, attach the speed sensor and secure to 71 inch lbs. (8 Nm).
- Attach the backing plate to the rear axle carrier.
