7. Turn wheel hub several times in both directions.
8. 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)
9. Measure wheel bearing axial end play.
Axial end play: 0 mm (0 in)
10. Measure starting force ``A'' at wheel hub bolt.
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 ``B'' at wheel hub bolt. Refer to step
10.
14. Wheel bearing preload ``C'' can be calculated as shown
below.
C=BþA
Wheel bearing preload ``C'':
7.06 - 20.99 N (0.72 - 2.14 kg, 1.59 - 4.72 lb)
15. Repeat steps 3 through 14 until correct axial end play and
wheel bearing preload are obtained.
16. Install free-running hub.
Front Wheel Alignment
Before checking front wheel alignment, make a preliminary
inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and proper inflation.
2. Check outside and inside wheel runout.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly by using the
standard bounce test.

Tire Rotation
lAfter rotating the tires, adjust the tire pressure.
lRetighten the wheel nuts after the aluminum wheel has
been run for the first 1,000 km (600 miles) or if a flat tire
occurs.
Wheel nuts:
: 118 - 147 N´m (12 - 15 kg-m, 87 - 108 ft-lb)
Checking Brake Fluid Level and Leaks
If fluid level is extremely low, check brake system for leaks.
Checking Brake System
Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasion, deterioration, etc.
Changing Brake Fluid
1. Drain brake fluid from each air bleeder valve.
2. Refill until new brake fluid comes out from each air bleeder
valve. Use same procedure as in bleeding hydraulic system
to refill brake fluid. Refer to BR section.
lRefill with recommended brake fluid (DOT 3 or DOT 4).
Refer to ``RECOMMENDED FLUIDS AND LUBRICANTS'',
MA-12.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.

Checking Steering Wheel Turning Force (For
power steering)
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine and run at idle speed or 1,000 rpm.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from neutral position.
Steering wheel turning force:
PB48S-type
24.5 - 29.4 N (2.5 - 3.0 kg, 5.5 - 6.6 lb)
PB59K-type
39 N (4 kg, 9 lb) or less
5. If steering wheel turning force is out of specification, check
the following:
a. Hydraulic system. Refer to ``Checking Hydraulic System'',
ST-7.
b. Steering Column. Refer to ST-10.
c. Front suspension and axle. Refer to FA section (``Front Axle
and Front Suspension Parts'', ``ON-VEHICLE SERVICE'').
d. Steering gear turning torque. Refer to ``TURNING TORQUE
MEASUREMENT'', ST-19 (PB48S), or ST-27 (PB59K).
Checking Steering Wheel Play
lPlace wheels in a straight ahead position and check steer-
ing wheel play.
Steering wheel play:
35 mm (1.38 in) or less
lIf it is not within specification, check the following for loose
or worn components.
a. Steering column. Refer to ST-10.
b. Front suspension and axle. Refer to FA section (``Front Axle
and Front Suspension Parts'', ``ON-VEHICLE SERVICE'').
c. Steering gear. [Refer to ST-13 (manual steering),ST-19
(power steering PB48S), or ST-27 (power steering PB59K).]
