- Place the car on stands.
- Remove the wheel cap and unscrew the wheel nuts.
- Remove the cotter pin from the wheel hub nut and unscrew the nut. To do this, have an assistant press the brake pedal. You can also loosen the nut while the car is on the ground.
- Remove the wheel.
- Unscrew the brake caliper from the shock absorber strut without removing the brake hose. Hang the caliper on a piece of wire, moving it to the side.
- Mark the outside of the hub and brake disc with paint or a felt-tip pen and remove the brake disc from the wheel hub.
- Before removing the wheel hub, check the axial play of the thrust bearing. To do this, install a dial indicator with a corresponding stand, as shown in Figure 191, and attach the measuring probe to the end of the drive shaft. Move the hub flange in both directions and take readings on the scale. If the play exceeds 0.05 mm, the bearing should be replaced.

- Pull the cotter pin out of the castle nut, unscrew the nut and use a puller to remove the hinge from the lever.
- If an ABS system is installed, unscrew the bolt securing the front wheel speed meter to the steering knuckle and pull out the sensor. Wrap the end of the sensor with adhesive tape to prevent dirt from getting in.
- Remove the bolt and two nuts on the underside of the wishbone and separate the wishbone from the suspension ball joint. Remove the lower part of the suspension strut from the steering knuckle as described in Chapter 12.1.1. Do not loosen the two bolts temporarily.
- Remove the wheel hub from the axle and pull out the hub together with the steering knuckle. Typically the hub is released by hitting the end of the shaft with a soft metal hammer. Otherwise, this requires a puller, which should be installed as shown in Figure 175.
- Knock out two bolts, connect the shock absorber strut to the steering knuckle and pull out the hub together with the steering knuckle.
