REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6 and 7
You will need a special tool to pull the bearing free of the halfshaft (drive axle), GM tool no. J-28733 or the equivalent. You should also use a halfshaft boot protector, GM tool no. J-33162 or the equivalent to protect the parts from damage on cars equipped with the 2.0L engine and boot protector J-34754 on all other engines.
- With the vehicle weight on the tires, break the hub nut loose.
- Raise and safely support the vehicle. Remove the wheel and tire assembly.
- Install a boot cover over the outer CV-joint boot.
- Remove the brake caliper and support it aside (on a wire); do not allow the caliper to hang on the brake line.
- Remove the rotor.
- Remove the hub nut.
- Unfasten the hub and bearing mounting bolts.
- Remove the brake rotor splash shield.
- Install J 28733 or equivalent hub puller tool, then turn the bolt and press the hub and bearing from the halfshaft.
- Disconnect the stabilizer link from the lower control arm.
- Remove the cotter pin and the ball joint-to-knuckle attaching nut.
- Separate the ball joint from the steering knuckle, using J 29330 or equivalent tool.
- Remove the halfshaft from the knuckle and support it aside.
- Matchmark the strut in relationship to the knuckle, for alignment purposes and remove the strut-to-knuckle attaching nuts.
- Remove the knuckle from the strut.
- Using a brass drift, remove the inner knuckle seal.
- Clean and inspect the steering knuckle bore and the bearing mating surfaces.
- Lubricate a new seal and the bearing with a high temperature wheel bearing grease, then using a driving tool, install the seal in the knuckle.
- Connect the ball joint to the knuckle and install the ball joint-to-knuckle attaching nut, hand tight.
- Position the knuckle to the strut and install the attaching bolts. Align the matchmarks and tighten the attaching bolts to 129 ft. lbs. (175 Nm) for 1988-90 vehicles, and to 133 ft. lbs. (180 Nm) for 1991-96 vehicles. Tighten the ball joint-to-knuckle attaching nut to 55 ft. lbs. (75 Nm) for 1988-90 vehicles, and to 26 ft. lbs. (35 Nm) plus 60 degree rotation for 1991-96 vehicles.
- Install a new O-ring between the bearing and knuckle assembly.
- Install the splash shield, hub/bearing assembly, to the knuckle and install the attaching bolts. Tighten the attaching bolts to 67 ft. lbs. (90 Nm) for 1988-90 vehicles and 70 ft. lbs. (95 Nm) for 1991-92 vehicles.
- Remove the boot cover from the outer CV-joint boot and slide the halfshaft into the knuckle assembly.
- Install the hub washer and attaching nut, (use and new nut) on the halfshaft. Tighten the attaching nut to a partial torque of 71 ft. lbs. (100 Nm), at this time.
- Connect the stabilizer link to the lower control arm.
- Install the brake rotor, caliper and the wheel/tire assembly.
- Lower the vehicle and final-tighten the hub nut to 191 ft. lbs. (259 Nm).
