4. Align the hub bore to the center of spindle with mechanical

supports. Gently push the hub assembly onto the spindle
until the seal is seated against the bearing shoulder. Rotate
the hub and lightly strike to ensure that the seal is properly
seated against bearing shoulder.

5. Pre-lube the outer bearing with the lubricant that is being

retained and place into the hub.

NOTE: When using grease, pre-pack the hub cavity. The

grease fill amount should be to a three o’clock
and nine o’clock level. This is to ensure a 50% hub
cavity fill. Use a template to hold grease in place
while filling the hub cavity (Figure 14).

7. Hub Bearing Adjustment

7.1. Hub Bearing Adjustment

Using 3-Piece Axle Nut

1. Install the bearing inner-axle adjustment nut finger tight

against the outer bearing (Figure 15).

2. While rotating the hub assembly, tighten the inner axle

adjustment nut to 200 ft.-lbs. (271 N•m).

3. Back off the inner axle adjustment nut one full turn and

then re-torque nut to 50 ft.-lbs. (68 N•m) while rotating
the hub assembly.

4. Back off inner axle nut approximately 1/4 turn and install

the axle lock washer (Figure 16). DO NOT include
socket backlash in the 1/4 turn.

5. Install the lock washer. If the hole in the washer is not

aligned with the pin on the inner nut, turn the washer
around and re-install. If the pin and hole are still not
aligned, slightly adjust parts as needed.

6. Install the outer axle nut finger tight against the axle

lock washer (Figure 16).

7. Tighten the outer axle nut to 300-400 ft.-lbs. (406-541 N•m).
