- On 1983-96 models, tighten the steering knuckle-to-lower arm retaining bolts to 83 ft. lbs. (112 Nm).
- Connect the ball joint to the lower suspension arm with the castellated nut and a new cotter pin. On 1987-88 models, tighten the nut to 67 ft. lbs. (91 Nm). On 1989-91 vehicles, tighten the nut to 90 ft. lbs. (123 Nm).
- Connect the ABS wheel speed sensor and position the rotor disc onto the axle hub.
- Connect the brake caliper to the steering knuckle.
- Have an assistant depress the brake pedal and tighten the bearing lock nut to 137 ft. lbs. (186 Nm).
- Install the adjusting nut cap with a new cotter pin. Using pliers, separate the cotter pin prongs and wrap them around the flats of the nut.
- Install the front wheels and lower the vehicle.
- Have the front wheel alignment checked.
See Figure 3
- Raise the vehicle and support safely. Remove the front wheels and the fender apron seal.
- Check the bearing backlash and axle hub deviation.
- Remove the two brake caliper set bolts.
- Hang the caliper using stiff wire on the shock absorber assembly.
- Remove the rotor.
- Place a dial indicator near the center of the axle hub and check the backlash in the bearing shaft direction.
- Backlash maximum should read 0.0020 inch (0.05mm). If the specification is greater than this, replace the bearing.
- Using the dial indicator, check the deviation at the surface of the axle hub outside and hub bolt. Maximum is 0.0020 inch (0.05mm). If greater than specified, replace the axle hub.
- Install the rotor and caliper assembly. Remove the cotter pin and lock cap off the center hub nut. Discard the cotter pin.
- While applying the front brakes, remove the drive shaft lock nut.
- Disconnect and separate the tie rod end from the steering knuckle.
- Remove the left and right stabilizer end brackets from the lower arms.
- Remove the 2 nuts and disconnect the lower arm from the ball joint.
- Remove the drive shaft from the axle hub. Secure the shaft out of the way using wire. Be careful not to damage the shaft boot or ABS sensor rotor.
- Remove the 2 brake caliper mounting bolts and remove the caliper. Support caliper from the vehicle using wire. Remove the brake rotor.
- If equipped with ABS, remove the sensor from the steering knuckle.
- Remove the 2 nuts on the lower end of the shock and remove the steering knuckle and hub assembly.
- Install the steering knuckle and hub assembly onto the vehicle and temporarily install the lower shock bolts.
- Connect the lower ball joint to the lower arm and tighten the bolt and nuts to 94 ft. lbs. (127 Nm).
- Connect the tie rod to the knuckle and tighten the nut to 36 ft. lbs. (49 Nm). Install new cotter pin.
- Tighten the nuts on the lower end of the shock to 156 ft. lbs. (211 Nm).
- Install both side stabilizer end brackets to the lower arm and tighten to 43 ft. lbs. (58 Nm).
- Install the front ABS sensor and tighten to 69 inch lbs. (8 Nm).
- Install the front brake rotor and caliper. Tighten the caliper mounting bolts to 79 ft. lbs. (107 Nm).
- Install the drive shaft locknut, and while applying the brakes, tighten to 217 ft. lbs. (294 Nm). Install lock cap and new cotter pin.
- Install front fender apron seal and the front wheel. Tighten the front wheel to 76 ft. lbs. (103 Nm).
See Figure 4
- Clamp the steering knuckle in a vise with soft jaws to protect the knuckle.
- Using screw driver, carefully pry the dust deflector from the hub.
- Drive out the bearing inner oil seal from the knuckle. On 1983-86 vehicles the seal is extracted with a puller. On 1987-96 vehicles, the seal is pried from the knuckle bore.
- After the seal is removed, use snapring pliers to remove the hole snapring from the knuckle bore.
- Unbolt and separate the dust deflector from the steering knuckle.
- Using a two-armed mechanical puller, pull the axle hub from the dust deflector.
- Using the puller, remove the inner (inside) bearing race from the bearing.
- Using Torx® wrench, remove the sensor control rotor from the axle hub.
- Using the puller, remove the outer bearing race. Set the outer race aside.
- Remove the outer bearing seal in the same manner as the inner seal.
- Take the inner (outside) race and install it inside the bearing.
- With a piece of brass stock, tap the bearing from the steering knuckle.
- Clean all the oil seal and bearing seating surfaces with a clean, dry rag.
- Install SST No. 09608-32010 into the bore of the steering knuckle and press the bearing into the bore. Leave the tool in place.
- Turn and insert the side lip of the new outer oil seal into the factory tool and drive the seal into the steering knuckle.
- Attach the brake disc cover to the steering knuckle with the bolts.
- Apply multi-purpose grease between the oil seal lip, oil seal and bearing and press the hub into the knuckle.
- Install a new snapring in the knuckle.
- Press a new oil seal into the knuckle and coat the seal with multi-purpose grease.
- Press the dust deflector into the knuckle. Make sure on vehicles with ABS, you align the holes for the speed sensor in the dust deflector and steering knuckle.
- Connect the ball joint to the steering knuckle and tighten the bolts to 94 ft. lbs. (127 Nm).
- Install the steering knuckle and hub assembly onto the vehicle as described earlier in this Section.
