Installation
Wheel bearings are sealed type When installing,
make sure that the sealed side of outer bearing
faces the axle shaft flange and that the sealed
side of inner bearing faces the companion
flange
Select a distance piece having a mark corre-
sponding to the mark on bearing housing
When a distance piece is reused, make sure that
both ends are not collapsed or deformed.
When installing, make sure that larger side faces
axle shaft flange.
