16.1 The bearing cover is attached to the wheel hub with hexagon socket bolts (1)
2. The wheel bearing can be replaced with the steering knuckle installed, but the drive shaft must be separated from the steering knuckle as described in the appropriate chapter. In doing so, do not disturb the connections to the drive.
3. The bearing and inner race remain on the inside of the steering knuckle and must be knocked out of it. The outer ring remains on the wheel hub; it must be removed with a puller (see illustration).
16.3 The rotating outer race of the bearing must be removed with 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 a special bearing grease. Fasten the cover with screws. Use a hex wrench.
5. Press the outer rotating ring into the hub. To do this, use a suitable tube with a diameter of 41 mm (see illustration).
16.5 Pressing the outer rotating ring of the bearing into the wheel hub. Press hole diameter (D) should be 41.0 mm.
6. Lubricate the gears of the axle shaft with «Loctite Scelbloc» and slide the shaft from behind into the steering knuckle and wheel bearing. Slide the hub with ring in place onto the drive shaft and hit the hub with a mallet until the end of the shaft comes out and the nut can be screwed onto it. Tighten the nut until 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 the final tightening when the car is lowered onto the wheels.
8. Perform the remaining work in reverse order. Tighten the caliper bolts to 35 Nm if the bolts were removed or to 100 Nm if the disc brake caliper was removed.
9. Lower the vehicle onto the wheels and tighten the drive shaft nut to 250 Nm. Refer to wheel tightening torque specifications.
