FRONT HUB
Disassembly
NOTE: Follow steps 1-10 for wheel/hub removal in
‘Front Drive Shaft (CV) Service / Removal’
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 the 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.
Assembly
1. Support bottom of hubstrut housing.
2. Start bearing in housing.
3. Press bearing into place until outer race bottoms on
housing.
4. Install snap ring into groove.
NOTE: Follow steps 2-6 for wheel/hub installation in
‘Front Drive Shaft (CV) Service / Installation’
CAUTION
When using an arbor press be sure to press only on
the outer race to avoid bearing damage.
