Front Axle Wheel Bearing

Front Wheel Bearing / INSPECTION AND ADJUSTMENT







Check that wheel bearings operate smoothly.

Check axial end play.

Axial end play:........................0 mm (0 inch)

Adjust wheel bearing preload if there is any axial end play or wheel bearing does not turn smoothly.







PRELOAD ADJUSTMENT (2WD MODELS)
Adjust wheel bearing preload after wheel bearing has been replaced or front axle has been reassembled.

1. Before adjustment, thoroughly clean all parts to prevent dirt entry.
2. Apply multi-purpose grease sparingly to the following parts:
- Threaded area of spindle
- Contact surface between lock washer and outer wheel bearing
- Grease seal lip Hub Cap

Hub cap grease:...............18 - 22 g (0.63 - 0.78 oz)







3. Tighten wheel bearing lock nut to the specified torque.

Tightening torque:.............34 - 39 Nm (3.5 - 4.0 kgf-cm, 25- 29 ft. lbs.)

4. Turn wheel hub several times in both directions to seat wheel bearing correctly.
5. Again tighten wheel bearing lock nut to the specified torque.

Tightening torque:......................34 - 39 Nm (3.5 - 4.0 kgf-cm, 25- 29 ft. lbs.)







6. Turn wheel bearing lock nut back 45 degrees.
7. Fit adjusting cap and new cotter pin. Align cotter pin slot by loosening nut 15 degrees or less.







8. Measure wheel bearing preload and axial end play.

Axial end play:.......................0 mm (0 inch)
Wheel bearing preload (As measured at wheel hub bolt)
New grease seal.....................9.8 - 28.4 N (1.0 - 2.9 kg, 2.2 - 6.4 lb)
Used grease seal........................9.8 - 23.5 N (1.0 - 2.4 kg, 2.2 - 5.3 lb)







Repeat above procedures until correct bearing preload is obtained.

9. Spread cotter pin.
10. Install hub cap.
