new bearing,
- the hub surfaces in contact with the new bearing.
| WARNING
To ensure that the wheel speed sensor works
properly, do not mark the sensor target on the
bearing. |
| WARNING
Do not press the bearing's internal bush so as to
avoid damaging the bearing (very high shrink-fitting
force). |
| Note:
It is essential to check the condition of the hub
surface and the hub carrier bore before refitting
the bearing. Replace the hub carrier if it is faulty. |
II - REFITTING OPERATION FOR PART
CONCERNED
- Refit:
- the front brake disc guard,
- the hub carrier bearing,
- the bolts of the front hub carrier bearing.
- Torque tighten the bolt of the front hub carrier
bearing (88 N.m).
