Wheel Bearing Adjustment
Installing Pro-Torq Spindle Nut
Install spindle nut as follows:
1. Remove the keeper ring from the nut as described in
the Removing Pro-Torq Spindle Nut section.
Do not attach, loosen, or tighten the Pro-Torq spindle nut
with the keeper ring in place. The keeper ring is a locking
device and must be removed before any adjustment of the
nut.
Care must be taken when removing the keeper ring from the
spindle nut due to the spring-like properties of the ring. Use
appropriate eye protection and shielding when servicing
this part.
2. To seat the steer axle bearing, thread the Pro-Torq
nut onto the axle spindle. While rotating the wheel,
torque the nut to 150 lbs. ft. (204 N•m).
3. After seating the bearing, back the nut off one full
turn.
4. To achieve the proper end-play, re-thread the Pro-
Torq nut until hand tight. Torque to 75 lbs. ft. (102
N•m).
5. Back nut off 1/3 turn, or one raised face mark on
surface of the Pro-Torq nut. Wheel should turn
freely.
6. Check end-play using a dial indicator. End-play
should be within .001" – .003" (.025 –.076 mm).
After seating bearing at 150 lbs. ft. (204 N•m), Pro-Torq
spindle nut must be backed off. Failure to back off the nut
will cause the bearing to run hot and fail prematurely or to
be damaged. The final adjustment of 75 lbs. ft. (102 N•m)
of adjusting torque with a 1/3 turn back off will ensure the
necessary .001" – .003"(.025 –.076 mm) end-play.
7. Insert the keeper ring into the undercut groove of the
spindle nut as shown.
8. Engage the mating teeth of the keeper and the nut.
9. Compress and insert the keeper arms one at a time
into the undercut groove of the nut.
10. Position the keeper ring as required to align teeth.
11. Do not turn the spindle nut to align teeth.
