STEERING LINKAGE
lCheck ball joint, dust cover and other component parts for
looseness, wear, damage or grease leakage.
Checking Power Steering Fluid and Lines
lCheck fluid level with engine off.
lCheck fluid level with dipstick on reservoir cap. Use ``HOT''
range at fluid temperatures of 50 to 80ÉC (122 to 176ÉF). Use
``COLD'' range at fluid temperatures of 0 to 30ÉC (32 to
86ÉF).
CAUTION:
lDo not overfill.
lRecommended fluid is Automatic Transmission Fluid
type ``DEXRONTMIIE'', ``DEXRONTMIII'' or equivalent.
lCheck lines for improper attachment, leaks, cracks, damage,
loose connections, chafing or deterioration.

Precautions
lWhen installing rubber parts, final tightening must be
carried 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.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
lAlways torque brake lines when installing.

Removal
lBefore removing the rear axle, disconnect the ABS
wheel sensor from the assembly. Then move it away
from the axle. Failure to do so may result in damage to
the sensor wires and the sensor becoming inoperative.
lWheel bearing does not require maintenance.
lIf growling noise is emitted from wheel bearing during
operation, replace wheel bearing assembly.
lIf the wheel bearing assembly is removed, it must be
renewed. The old assembly must not be re-used.
1. Disconnect parking brake cable and brake tube.
2. Remove nuts securing wheel bearing cage with baffle plate.
3. Draw out axle shaft with Tool.
When drawing out axle shaft, be careful not to damage oil
seal.
4. Remove case shim and case seal.
Ð 2WD and 4WD models without ABS Ð
5. Remove O-ring. Ð 4WD models with ABS Ð
6. Remove oil seal.
Do not reuse oil seal once it is removed.
Always install new one.
7. Remove ABS sensor rotor. Ð 4WD models with ABS Ð
8. Unbend lock washer with a screwdriver.

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).]
