3. Inboard-bearing race
2. Remove the seal, inboard bearing from the hub
(Figure 26).
3. Wipe clean the seal and check for wear and
damage.
Note:
Do not use cleaning solvent to clean the
seal. Replace the seal if it is worn or damaged.
4. Clean the bearings and races, and check these
parts for wear and damage.
Note:
Replace all worn or damaged parts.
Ensure that the bearings and races are clean
and dry.
5. Clean the cavity of the hub of all grease, dirt,
and debris (Figure
6. Pack the bearings with the specified grease.
7. Fill the cavity of hub 50 to 80% full of the
specified grease
8. Assemble the inboard bearing onto the race at
the inboard side of the hub and install the seal
(Figure 26).
9. Repeat steps 1 through
other hub.

2. Spindle nut
3. Tab washer
2. Assemble the hub and rotor onto the spindle
with the rotor inboard
3. Assemble the outboard bearing onto the spindle
and seat the bearing to the outboard race
(Figure 27).
4. Assemble the tab washer onto the spindle
(Figure 27).
5. Thread the spindle nut onto the spindle and
tighten the nut to 15 N∙m (11 ft-lb), while rotating
the hub to seat the bearing
6. Loosen the spindle nut until the hub rotates
freely.
7. Torque the spindle nut to 170 to 225 N∙cm (15
to 20 in-lb).
8. Install the retainer over the nut and check the
alignment of the slot in the retainer and the hole
in the spindle for the cotter pin
Note:
If the slot in the retainer and the hole in
the spindle are not aligned, tighten the spindle
nut to align the slot and hole to a maximum
torque of 226 N∙cm (20 in-lb) on the nut.
