TROUBLESHOOTING
Troubleshootings are classified into master trouble-
shooting and group troubleshooting and located as
follows:
The master troubleshooting is prepared when the
trouble symptom relates to two or more groups and
given in MASTER TROUBLESHOOTING.
The group troubleshooting guide is prepared for
causes of problems related to that individual group
only; a troubleshooting guide is prepared for each
appropriate group.LIMIT

Remove the oil seal (drive shaft side) from the knuckle.
5. REMOVAL OF WHEEL BEARING
(1) Crush the oil seal in two places so that the tabs of the
special tool will be caught on the wheel bearing inner
race.(2) Remove the wheel bearing inner race from the front
hub by using the suitable puller.
NOTEBe careful that the front hub will not fall down at the
wheel bearing inner race (outer side) removed from the
hub.(3) Remove the snap ring from the knuckle.
(4) Remove the bearing by using the special tools.
Caution
Removal is easier if the outer side inner race
removed from the hub is placed on the bearing and
the wheel bearing is then removed.
INSPECTIONNOZffiAkh
0Check the front hub and brake disc mounting surfaces for
galling and contamination.
l Check the knuckle inner surface for galling and cracks.
0 Check for defective bearing.
