Precautions
PRECAUTIONSNBAX0001IWhen installing rubber parts, final tightening must be car-
ried out under unladen condition* with tires on ground.
*Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
IUse flare nut wrench when removing and installing brake
tubes.
IAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
IAlways torque brake lines when installing.

FRONT WHEEL BEARINGNBAX00051. Check that wheel bearings operate smoothly.
2. Check axial end play.
Axial end play: 0 mm (0 in)
3. Adjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.
Preload AdjustmentNBAX0005S01Adjust 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.
SFA891-A
2. Apply multi-purpose grease sparingly to the following parts:
IThreaded portion of spindle
IContact surface between wheel bearing lock washer (cham-
fered side) and outer wheel bearing
IGrease seal lip
IWheel hub (as shown at left)

3. Tighten wheel bearing lock nut with Tool.
: 78 - 98 N´m (8 - 10 kg-m, 58 - 72 ft-lb)
4. Turn wheel hub several times in both directions.
5. Loosen wheel bearing lock nut so that torque becomes 0 N´m
(0 kg-m, 0 ft-lb).
6. Retighten wheel bearing lock nut with Tool.
: 0.5 - 1.5 N´m (0.05 - 0.15 kg-m, 4.3 - 13.0 in-lb)

11. Install lock washer by tightening the lock nut within 15 to 30
degrees.
12. Turn wheel hub several times in both directions to seat wheel
bearing correctly.
13. Measure starting force ªBº at wheel hub bolt. Refer to proce-
dure 10.
14. Wheel bearing preload ªCº can be calculated as shown below.
C=BþA
Wheel bearing preload ªCº:
7.06 - 20.99 N (0.72 - 2.14 kg, 1.59 - 4.72 lb)
15. If wheel bearing preload ªCº is outside specifications, remove
lock washer. Tighten or loosen lock nut within±15 degrees
(Refer to step 11 above). Install lock washer, then repeat steps
12, 13 and 14.
16. Repeat above procedures until correct axial end play and
wheel bearing preload are obtained.
17. Install drive flange and wheel hub cap.
