REAR HUB DISASSEMBLY
1. Remove outer snap ring.
2. From the back side, tap on the outer bearing race
with a drift punch in the reliefs as shown.
NOTE: Drive bearing out evenly by tapping on outer
race only. Once bearing is at bottom of casting,
support casting on outer edges so bearing can be
removed.
3. Inspect bearing.
NOTE: Due to extremely close tolerances and
minimal wear, the bearings must be inspected
visually, and by feel. While rotating bearings by hand,
inspect for rough spots, discoloration, or corrosion.
The bearings should turn smoothly and quietly, with
no detectable up and down movement and minimal
movement sideways between inner and outer race.
4. Inspect bearing housing for scratches, wear or
damage. Replace housing if damaged.
REAR HUB ASSEMBLY
1. Support bottom of bearing carrier housing.
2. Start bearing in housing.
3. Press bearing into place until outer race bottoms
on housing.
