REMOVAL & Installation
See Figures 1, 2, 3 and 4
- Raise and safely support the vehicle.
- Remove the rear wheel and tire assembly.
- If equipped with rear disc brakes, unbolt the rear caliper and suspend it from frame of the vehicle with a piece of wire. Do NOT let the caliper hang by the brake hose.
- If equipped with rear disc brakes, remove the brake rotor. If equipped with rear drum brakes, remove the brake drum from the hub.
- If equipped with ABS, remove the wheel speed sensor from the rear disc brake adapter.
- Remove the hub/bearing retaining nut, then remove the hub and bearing from the knuckle. Discard the hub nut and replace with a new one during installation.
- If equipped with drum brakes, remove the 4 bolts attaching the rear brake support plate to the knuckle. Then, remove the brake support plate, brake shoes and wheel cylinder as an assembly from the rear knuckle. You do not have to disconnect the brake hose from the wheel cylinder when removing the support plate. After you remove the brake plate, it must be supported in the same way as the caliper.
- If equipped with disc brakes, remove the 4 bolts attaching the disc brake adapter to the rear knuckle. Then, remove the adapter, rotor shield, parking brake shoes and parking brake cable from the knuckle as an assembly.
The knuckle-to-strut bolts are serrated and must not be turned during removal. Loosen and remove the nuts while holding the bolts stationary in the knuckle.
- Loosen, but do not remove, the 2 strut-to-knuckle bolts. Then, remove the lateral link-to-knuckle attaching bolt.
- Hold the tension strut from turning using a large adjustable wrench on the flat of the tension strut, then remove the tension strut nut. Then, remove the nut, tension strut retainer and rear tension strut bushing from the tension strut at the rear knuckle.
- Remove both rear knuckle-to-strut assembly clevis bracket bolts. If the vehicle is equipped with a rear sway bar, also remove the sway bar link-to-strut mounting bracket.
- Remove the knuckle assembly from the strut by sliding the knuckle straight out of the clevis bracket on the strut. Then, remove the knuckle from the tension strut.
- Insert the tension strut, tension strut bushing and tensioner strut retainer into the knuckle. Then, install the knuckle into the clevis bracket on the rear strut assembly. Make sure the stepped area of the bushing is squarely seated into the hole in the knuckle.
- Install the 2 strut clevis bracket-to-knuckle bolts and nuts. Hold the bolts stationary, then tighten the nuts to 70 ft. lbs. (95 Nm).
- Install the lateral arms-to-knuckle attaching bolt, washers and nut as shown in the accompanying figure. Do NOT tighten the lateral link bolt yet. The vehicle must be at curb height when tightening the link bolts.
- Install the tension strut bushing, tension strut retainer and nut on the tension strut. When installing the tension strut retainers, the retainers must be installed on the tension strut, with the cupped side of the retainer facing away from the bushing and knuckle.
- Place a large adjustable wrench on the flat of the tension strut to keep it from turning, then tighten the tension strut nut to 70 ft. lbs. (95 Nm).
- If equipped with rear drum brakes, install the brake support plate onto the knuckle. Secure with the 4 bolts and tighten to 50 ft. lbs. (68 Nm).
- If equipped with rear disc brakes, install the adapter on the knuckle. Install the 4 retaining bolts and tighten to 50 ft. lbs. (68 Nm).
- If equipped with ABS, install the speed sensor head into the brake support plate or disc brake adapter. Tighten the wheel speed sensor mounting bolt to 60 inch lbs. (7 Nm).
The hub/bearing nut must be tightened to, but NOT over, its specified torque value. The proper specification is crucial to the life of the hub bearing.
- Install the hub and bearing on the steering knuckle. Install the a new retaining nut and tighten to 160 ft. lbs. (217 Nm).
- If equipped with rear disc brakes, install the rotor on the hub. Carefully install the caliper over the rotor and on the adapter. Tighten the caliper mounting bolts to 16 ft. lbs. (22 Nm).
- Install the wheel and tire assembly. Tighten the lug nuts in sequence to 100 ft. lbs. (135 Nm).
- Carefully lower the vehicle.
- With the weight of the vehicle supported by the suspension, and the links at the proper height, tighten the lateral link attaching bolts to 70 ft. lbs. (95 Nm).
- Have the toe checked and adjusted as necessary.
