16.1 The bearing cap is secured to the wheel hub with hexagon socket head bolts (1)
2. The wheel bearing can be replaced with the steering knuckle installed, but it is necessary to separate the drive shaft from the steering knuckle as described in the relevant chapter. Do not disturb the connections to the drive.
3. The bearing and inner ring remain on the inside of the steering knuckle and must be knocked out. The outer ring remains on the wheel hub; it must be removed using a puller (see illustration).
16.3 The outer rotating ring of the bearing must be removed using a wheel hub puller
4. Install the inner parts of the wheel bearing into the steering knuckle. Lubricate the bearing balls, rotating rings and seal lips with special bearing grease. Secure the cover with bolts. Use an Allen key.
5. Press the outer rotating ring into the hub. Use a suitable 41 mm diameter tube for this (see illustration).
16.5 Pressing the outer rotating ring of the bearing into the wheel hub. The diameter of the press hole (D) should be 41.0 mm.
6. Lubricate the axle shaft gears with "Loctite Scelbloc" and push the shaft from the back into the steering knuckle and wheel bearing. Put the hub with the installed ring on the drive shaft and hit the hub with a mallet until the end of the shaft comes out and you can screw a nut on it. Tighten the nut so that there is enough room on the shaft for the disc, remove the nut again, install the disc and tighten the nut with your fingers.
7. Perform final tightening when the vehicle is lowered onto its wheels.
8. Perform the remaining work in the reverse order. Tighten the caliper bolts with a tightening force of 35 Nm if the bolts were removed, or with a tightening force of 100 Nm if the disc brake caliper was removed.
9. Lower the vehicle onto its wheels and tighten the drive shaft nut to 250 Nm. For wheel tightening torque, see specifications.
