Removal
Note: If the wheel cover is not secured with wheel nuts, begin with the procedure in paragraph 4.
1. Loosen the wheel nuts, jack up the front of the car and place it on supports.
2. Loosen the wheel nuts and remove the decorative cap from the disk, remove the wheel.
3. Use a drift to flatten the hub nut washer, then reinstall the wheel without the cap and lower the vehicle to the ground.
4. Using a long-handled socket wrench, loosen the hub nut.
5. Loosen the wheel nuts, jack up the front of the car and place it on supports. Remove the wheel and loosen the hub nut.
6. Release the flexible brake hose from the bracket on the steering knuckle assembly. Unbolt the brake caliper and tie it with wire to the coil spring. Also remove the caliper anchor bracket and the brake disc (see Chapter Brake system).
7. Remove the two mounting screws and remove the brake disc from the hub assembly (see Chapter Brake system).
8. Remove the ABS wheel sensor (see Chapter Brake system).
9. Disconnect the steering tie rod end from the steering knuckle (see Section Removal and installation tie rod ends).
10. Separate the lower control arm from the ball joint at the bottom of the steering knuckle (see Section Removal and installation the lower control arm of the front suspension).
11. Separate the upper end of the knuckle from the upper control arm ball joint (see Section Removal and installation the upper control arm of the front suspension).
12. Carefully pull the knuckle and hub assembly outward, removing it from the drive shaft journal. If necessary, tap the end of the journal with a soft-faced hammer to release the CV joint from the hub. Tie the drive shaft assembly with wire to avoid damaging the inner CV joint.
13. If there is a need to replace the wheel bearing, deliver the steering knuckle assembly to an auto service workshop.
Installation
1. If you dismantled the assembly, install the hub on the steering knuckle (the work must be performed in a car service workshop).
2. Lightly lubricate the splines of the outer journal of the drive shaft with special grease. Pass the journal through the hole in the hub, simultaneously tucking the steering knuckle into place.
3. Connect the upper part of the knuckle to the ball joint of the upper control arm (see Section Removal and installation the upper control arm of the front suspension). Tighten the ball joint nut to the required torque and secure it with a new cotter pin.
Note: Tighten the nut to the minimum allowable force, then tighten it until the holes for the cotter pin fit are aligned.
4. Connect the ball joint at the bottom of the knuckle to the lower control arm (see Section Removal and installation the lower control arm of the front suspension). Tighten the castle nut to the required torque and secure it with a new cotter pin (see Note in the previous paragraph).
5. Install the brake disc in place, tightening the mounting screws securely.
6. Install the anchor bracket and support, tightening the component fasteners to the required torque (see Chapter Brake system). Secure the flexible brake hose to the support bracket on the steering knuckle assembly. Tighten the mounting bolts securely.
7. Screw the hub nut onto the drive shaft journal and tighten it securely.
8. Install the wheel (if necessary, the hubcap), lower the vehicle to the ground and tighten the wheel nuts to the required torque (see Specifications in Chapter Settings and ongoing maintenance).
9. Tighten the hub nut to the required torque (see Specifications in Chapter Clutch and drive shafts).
