Remove a spacer nut from the axle assembly in
the caster wheel.
Note:
Thread-locking adhesive has been
applied to lock the spacer nuts to the axle.
Remove the axle (with the other spacer nut still
assembled to it) from the wheel assembly.
Pry out seals and inspect bearings for wear or
damage and replace if necessary.
Pack the bearings with a general-purpose
grease.
Insert 1 bearing and 1 new seal into the wheel.

and thread it onto the axle with the wrench flats
facing outward.
