Wheel Bearing: Adjustments
Front Wheel Bearing Adjustment
Notice: Never preload the front wheel bearings. Damage can result by the steady load on the roller ends that comes from preloading.
Important:
^
In order to maintain the continuous, smooth functioning of the front suspension, the front wheel bearings must be correctly adjusted.
^
The bearings must be a slip fit on the spindle and the wheel bearings must be lubricated in order to ensure that the roller bearings will roll and not
skid.
^
The spindle nut must have a free-running fit on the spindle threads.
1. Raise the vehicle. Support the vehicle with suitable safety stands.
2. Remove the retainer cap (9).
Notice: Refer to Fastener Notice in Service Precautions.
3. Remove the cotter pin (8).
^
Tighten the nut (7) to 16 Nm (12 lb ft), while rotating the wheel and tire assembly, or the hub/rotor. This will seat the bearings.
4. Back off the nut one flat.
^
If the hole in the spindle lines up with the slot in the nut, insert the cotter pin.
^
If these do not line up, back off the nut until the hole and the slot line up. Do not back off the nut more than one additional flat.
5. Measure the endplay in the hub/rotor. This measurement should be between 0.013 - 0.20 mm (0.0005 - 0.008 inch) when properly adjusted.
6. Install the retainer cap.
7. Lower the vehicle.
