Inspection on Steering Knuckle
Check the steering knuckle
Check the steering knuckle with the dye penetration agent to
see whether the steering knuckle has a crack or not.
If the crack is found, the steering knuckle is required to be
changed.

(d) Conduct the dynamic balance test on the dynamic balancer,
the amplitude value displayed should not be above 13.5g
under the condition that the measuring rotating velocity
is 796 r/m and the locking rotating velocity 786 r/m,
otherwise, tap in the counter balanced clip, which is 4g
each, at the corresponding location, the number of the
clip should not be more than 4.
(e) Tap in the new bearing outer race with the special service
tool.
Notice: the inner and outer races of bearing should be
changed in set.
Assembly of Front Wheel Hub
1.Mount on the inner race and roller assembly of front hub
bearing (inner) as well as the front hub oil seal.
Coat the lithium base grease of 4 to 5 mm on the inside surface of
the bearing outer race and front wheel hub, and plaster the
lubricant in the front hub bearing (inner) and the roller assembly.
Coat a little lubricant on the lips of oil seal of front wheel hub, and
then tap the oil seal of front hub in place with special service tool.
Notice: do not coat the lubricant on the front brake disc face.
