Wheel Bearing: Adjustments

PRELOAD ADJUSTMENT
Adjust wheel bearing preload after wheel bearing has been replaced or front axle has been reassembled. Adjust wheel bearing preload as follows:
1. Before adjustment, thoroughly clean all parts to prevent dirt entry.
2. Apply multi-purpose grease sparingly to the following parts:
Threaded portion of spindle.
Contact surface between wheel bearing washer and outer wheel bearing.
Grease seal lip.
Wheel hub, as shown.





3. Tighten wheel bearing lock nut with wheel bearing lock nut wrench tool No. KV40105400, or equivalent, to 78 - 98 Nm (58 - 72 ft. lbs.).
4. Turn wheel hub several times in both directions.
5. Loosen wheel bearing lock nut so that torque becomes O Nm (O ft. lbs.).
6. Retighten wheel bearing lock nut with lock nut wrench tool to 0.5 - 1.5 Nm (4.3 - 13.0 inch lbs.)
7. Turn wheel hub several times in both directions.
8. Retighten wheel bearing lock nut with Lock nut wrench tool to 0.5 - 1.5 Nm (4.3 - 13.0 inch lbs.)





9. Measure wheel bearing axial end play. Axial end play: O mm (O inch)





10. Measure starting force "A" at wheel hub bolt.





11. Install lock washer by tightening the lock nut within 15 - 30°.
12. Turn wheel hub several times in both directions to seat wheel bearing correctly.
13. Measure starting force "B" at wheel hub bolt. Refer to step 10.
14. Wheel bearing preload "C" can be calculated as C = B - A. Wheel bearing preload "C": 7.06 - 20.99 N (1.59 - 4.72 lbs.)
15. Repeat steps 3 through 14 until correct axial end play and wheel bearing preload are obtained.
16. Install free-running hub.
