Keep the dust cap off until greasing is done. Refer to

with the wrench flats facing outward. Do Not thread
spacer nut all of the way onto the end of the axle.
Leave approximately 1/8 inch (3 mm) from the outer
surface of the spacer nut to the end of the axle inside
the nut.

the side of the wheel with the new seal and bearing.

the area inside the wheel around the axle full of
general-purpose grease.
