Note: You will need a new hub nut, ball joint pinch bolt nut, and hub assembly pinch bolt nut for assembly.
Removal
1. Remove the wheel/hub cap, then loosen the drive shaft nut and wheel mounting bolts.
2. Support the rear wheels with chocks, set the parking brake, then jack up the front of the car and place it on supports. Remove the corresponding front wheel.
3. On models equipped with ABS, unbolt the wheel sensor and, without disconnecting the electrical wiring, move it away from the hub assembly (see Chapter Removal and installation the front suspension stabilizer bar struts).
4. Loosen the hub nut and remove the washers. If you forgot to loosen the nut while the car was on the ground, screw a pair of washers into the hub (at least) wheel mounting bolts and tighten them securely, then have an assistant firmly press the foot brake pedal to lock the hub from turning and loosen the nut.
Note: During assembly, the hub nut must be replaced without fail.
5. Remove the cotter pin and loosen the nut securing the tie rod end to the steering arm of the hub assembly. Use a ball joint puller to release the end from the arm.
6. If you are going to remove the wheel bearings, remove the brake disc, otherwise screw in the two bolts that secure the caliper assembly to the hub with the anchor bracket and remove the assembly from the brake disc. Tie the caliper to the suspension spring with wire - try not to overstretch the flexible brake hose.
7. On models equipped with an anti-roll bar, loosen the nut securing the stabilizer bar strut to the lower suspension arm, remove the washer and take out the rubber insert.
8. On all models, loosen the nut and remove the lower control arm ball joint clamp bolt from the base of the hub assembly. Using a pry bar, carefully lower the lower control arm, freeing the ball joint from its mounting clamp in the hub assembly. On models equipped with an anti-roll bar, be careful not to allow the rubber cushion and washer of the upper stabilizer bar mount to fall out.
Note: The ball joint tension bolt must be replaced without fail (comes with its own nut).
9. Loosen the nut and remove the tie bolt securing the hub assembly to the suspension strut.
Note: The tie bolt nut must be replaced without fail.
10. Separate the hub assembly from the strut, then remove it from the splined outer CV joint journal of the drive shaft and remove it from under the vehicle. If the assembly does not separate from the strut, use a large flat-head screwdriver to gently spread the jaws of the mounting clamp. If the strut fits too tightly on the shaft journal, knock it off with a soft-faced hammer.
Installation
1. Thoroughly clean the hub and outer CV joint journal splines of the drive shaft. Place the hub assembly on the shaft journal until it stops, install the washer, then screw on the new hub nut. Tighten the nut lightly.

2. Place the hub assembly on the suspension strut, inserting the ear of the latter into the groove of the clamp. Achieve alignment of the holes, then insert the clamp bolt, screw on a new nut and tighten it to the required force.
3. Ensure that the lower control arm ball joint is correctly positioned with the hub assembly clamp, insert the tie bolt, screw on a new nut and tighten it to the required torque. On models equipped with an anti-roll bar, position the stabilizer bar strut on the lower control arm, ensuring that the rubber insert and upper support washer are correctly positioned.
4. Where required, install the rubber insert and lower support washer on the stabilizer bar, screw on the fastening nut and tighten it to the required force.
5. Properly insert the ball joint tail of the tie rod end into the seat in the hub assembly and tighten its mounting nut securely. Secure the nut with a new cotter pin.
6. Where required, install the brake disc on the hub (see Chapter Brake system). Place the caliper assembly with the anchor bracket in place - make sure that the brake pads are seated correctly on both sides of the disc. Tighten the anchor bracket mounting bolts to the required torque (see Chapter Brake system).
7. On models with ABS, reinstall the wheel sensor (see Chapter Brake system).
8. Replace the wheel, then lower the vehicle to the ground and tighten the wheel nuts to the required torque.
9. Finally tighten the hub nut to the required torque, then install the disc/hub cap.
