hubcap, or drive axle shaft
for a drive hub, to receive the
draining oil, then remove the
hubcap or drive axle shaft.
Do not reuse the oil. Correctly

determine the type of locking
system. Disengage the locking
device.
Do not loosen the axle spindle nuts by either
striking them directly with a hammer, or striking
a drift or chisel placed against them. Damage to
the parts will occur causing possible loss of axle
wheel-end components and serious personal
injury.

9. Remove the spindle nut system.
10. Slide the hub off the spindle.
Remove and save the outer
bearing cone. Be careful when
you remove the hub that you do
not damage the outer bearing
by dropping it on the floor.
-
If the hub is difficult to remove
because the seal or bearings
are stuck on the spindle, use
a mechanical puller to remove
the hub (see figure 43).
-
If part of the seal remains on
the spindle, carefully remove
the part of the seal that
remains on the spindle.
This can be done by striking the remaining portion
of the seal with the round end of a ball-peen
hammer. Use caution not to damage the seal
journal on the spindle.
