AXLE SHAFT, REMOVE/INSTALL
Remove
1: Remove the front axle nut.
2: Slowly raise the front of the vehicle until the axle
can slide freely out of the fork. The front wheel(s)
should still be resting on the ground.
3: Remove the front axle from the fork and support
the vehicle with jack stands.
Note: If the bearings were worn until they were
broken, then the shaft may have to be cut
out of the fork.
4: Inspect the axle shaft and holes in the fork for the
shaft.
• If there is any noticeable wear on the shaft then it
should be replaced.
• The holes in the fork should be round. If worn in an
oval then the fork should be replaced.
Install
1: Raise the front of the vehicle so that the hole for
the axle is the same height as the front wheel
hub.
2: Assemble the bearing spacers into the front
wheel hub and place the front wheel(s) into the
fork.
3: Insert the axle into the front fork.
4: Lubricate the bearings.
5: Install the axle nut(s). Refer to Adjust Front
Wheel Bearings section for information regarding
tightening the front axle.
