NOTE
The bearing cups (races) are a press fit in
the wheel hub and should not be removed
unless a new part is to be installed. To re-
move the bearing cup, heat wheel hub in
boiling water for 30 minutes, or in an oven
not to exceed 121°C (250°F). Using an
arbor press, if available, press out the
bearing cup and press in the new bearing
cup while the wheel hub is still hot.
