Because of the heavy weight of the wheel and
tire, it is suggested to first remove the wheel
and tire assembly from spindle when servic-
ing the bearings to avoid damage to the
grease seal when the wheel hub is moved off
or on the spindle. It also makes the work sim-
pler and easier.
2. Refer to the exploded view illustration of the wheel
bearing assembly. Loosen and remove the hubcap
from wheel or hub. You may have to lightly tap hub
cap with a hammer and chisel and use a pry bar to
loosen. Be careful not to damage mounting surfaces.
Remove O-ring from hubcap.
3. Clean the excess grease from around the wheel nut.
4. Remove cotter pin, loosen and remove wheel nut and
bearing washer.
