bearing as well as the oil seal of front hub.
Coat the lithium base grease of (4-5)mm on the inside surfaces
of the bearing outer race and the front wheel hub, put in the
inner race and roller assembly of front hub bearing (inner),
then plaster the lubricant. Plaster a little lubricant on the lips of
front wheel hub oil seal, and finally tap the front hub in place
with special service tool.
