The bearing has a signal disk for the wheel speed sensor, take care not to damage the disk (if any) when installing the bearing
Remove
Remove the steering knuckle.
Using a press, press the hub out of the bearing, placing a mandrel with an outer diameter of 36.5 mm on it, and a puller under the steering knuckle (Fig. 1).
You can, of course, clamp the steering knuckle in a vise and knock out the hub with a suitable mandrel (Fig. 2)
We press the inner ring of the bearing out of the hub using a puller.
Install the jaws of the puller into the groove of the wheel bearing inner race and remove it.
Remove the bearing circlip.
Remove the outer ring of the bearing by resting a piece of pipe with an outer diameter of 65 mm against the inner ring (Fig. 4).
Do not use the probe holder (if installed) as a support.
You can use a puller (Fig. 5)
Installation
Do not move the vehicle with the wheels not installed in the hubs and the drive shafts not tightened to the required torque, as this can lead to the destruction of the wheel hub bearings and damage to the ABS signal disc.
Be sure to check the condition of the hub surface and knuckle bore before installing the bearing. Replace the damaged steering knuckle.
Clear:
- - inner and outer surfaces of the new bearing in contact with the steering knuckle and the hub;
- - surfaces of the steering knuckle in contact with the new bearing;
- - hub surfaces in contact with the new bearing.
Install the sensor holder.
If the vehicle is equipped with a wheel speed sensor, position the sensor holder at an angle X - 35° ±5° from the vertical axis of the steering knuckle: this position corresponds to the center of the seat (Fig. 4).
To press the bearing, install a mandrel with an outer diameter of 70 mm on the outer ring (Fig. 7).
In order not to damage the bearing, do not lean on the inner ring, as the pressing force of the bearing is very high.
Install the bearing circlip.
To press the bearing, install a mandrel with an outer diameter of 50 mm on the inner ring (Fig. 8).
Install the steering knuckle assembly with the hub and bearing on the car.

- - ball joint bolt th suspension arm support (62 Nm);
- - Tie rod end ball joint pin nut (37 Nm);
- - hub nut (280 Nm);
- - bolts for fastening the shock absorber to the steering knuckle (105 Nm);
- - brake disc mounting screws (140 Nm);
- - bolt for fastening the guide pads (105 Nm);
- - wheel bolts (110 Nm).
