Wheel Bearing

21.Wheel Bearing

A: INSPECTION

1. FRONT WHEEL BEARING

NOTE:
Inspect the condition of front wheel bearing grease.
1) Jack-up the front side of vehicle.
2) While holding the front wheel by hand, swing it in
and out to check bearing free play.
3) Loosen the wheel nuts, and remove the front
wheel.
4) If the bearing free play exists in step 2) above,
attach a dial gauge to the hub and measure axial
play in axial direction.

Service limit:

Straight-ahead position within 0.05 mm 
(0.0020 in)

5) Remove the bolts and self-locking nuts, and ex-
tract the front arm from front crossmember.
6) Remove the PTJ of front drive shaft from trans-
mission. <Ref. to DS-13, Front Axle.>
7) While supporting the front drive shaft horizontal-
ly with one hand, turn the hub with the other hand to
check for noise or binding.
If the hub is noisy or binds, replace the front axle.

2. REAR WHEEL BEARING

1) Jack-up the rear side of vehicle.
2) While holding the rear wheel by hand, swing it in
and out to check bearing free play.
3) Loosen the wheel nuts, and remove the rear
wheel.
4) If the bearing free play exists in step 2) above,
attach a dial gauge to the hub and measure axial
play in axial direction.

Service limit:

Straight-ahead position within 0.05 mm 
(0.0020 in)

5) Remove the DOJ of rear drive shaft from rear dif-
ferential. <Ref. to DS-26, Rear Drive Shaft.>

6) While supporting rear drive shaft horizontally
with one hand, turn the hub with the other hand to
check for noise or binding.
If the hub is noisy or binds, replace the rear axle.

place them with new ones. <Ref. to DS-22, Front
Drive Shaft.> <Ref. to DS-26, Rear Drive Shaft.>

Steering)

A: INSPECTION

1. STEERING WHEEL

1) Set the steering wheel in a straight-ahead posi-
tion, and check the wheel spokes to make sure
they are correctly set in their specified positions.
2) Lightly turn the steering wheel to the left and
right to determine the point where front wheels start
to move.
Measure the distance of the movement of steering
wheel at the outer periphery of wheel.

Steering wheel free play:

0 — 17 mm (0 — 0.67 in)

Move the steering wheel vertically toward the shaft
to ascertain if there is play in the direction.

Maximum permissible play:

0.5 mm (0.020 in)

3) Drive the vehicle and check the following items
during operation.

(1) Steering force:
The effort required for steering should be
smooth and even at all points, and should not
vary.
(2) Pulled to one side:
Steering wheel should not be pulled to either
side while driving on a level surface.
(3) Wheel runout:
Steering wheel should not show any sign of
runout.
(4) Return factor:
Steering wheel should return to its original posi-
tion after it has been turned and then released.

2. STEERING SHAFT JOINT

When the steering wheel free play is excessive,
disconnect the universal joint of steering shaft and
check it for any play and yawing torque (at the point
of the crossing direction). Also inspect for any dam-
age to sealing or worn serrations. If the joint is
loose, retighten the mounting bolts to the specified
torque.

3. GEARBOX

1) With the vehicle placed on a level surface, turn
the steering wheel 90

° in both the left and right di-

rections.
While the wheel is being rotated, reach under the
vehicle and check for looseness in gearbox.

Tightening torque:

tion.

3) With the vehicle placed on a level surface, quick-
ly turn the steering wheel to the left and right.
While steering wheel is being rotated, check the
gear backlash. If any noise is noticed, adjust the
gear backlash.
4) Adjustment for LHD model

(1) Apply liquid gasket around the center of ad-
justing screw thread.
(2) Tighten adjusting screw to 25 N

⋅m (2.5 kgf-

m, 18.4 ft-lb) and then loosen.
(3) Tighten adjusting screw to 3.9 N

⋅m (0.40

kgf-m, 2.9 ft-lb) and then loosen 20

°.

5) Adjustment for RHD model

(1) Apply liquid gasket around the center of ad-
justing screw thread.
(2) Tighten adjusting screw to 9.8 N

⋅m (1.0 kgf-

m, 7.2 ft-lb) and then loosen.
(3) Tighten adjusting screw to 4.9 N

⋅m (0.50

kgf-m, 3.6 ft-lb) and then loosen approx 30

°.

4. TIE-ROD

1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.

2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If castle nut is loose, retight-
en it to the specified torque, then tighten further up
to 60

° until cotter pin hole is aligned.

5. POWER STEERING FLUID LEVEL

NOTE:
• At power steering fluid temperature 20

°C (68°F);

read the fluid level on the “COLD” side.
• At power steering fluid temperature 80

°C

(176

°F); read the fluid level on the “HOT” side.

1) Place the vehicle with engine “OFF” on a level
surface.
2) Remove the cover. (3.0 L and turbo model)
3) Check the fluid level using the scale on the out-
side of the reservoir tank (A). If the level is below
“MIN” (B), add fluid to bring it up to “MAX” (C).

NOTE:
If fluid level is at MAX level or above, drain fluid to
keep the level in the specified range of indicator by
using a syringe or the like.

Recommended fluid:

Refer to “RM” section. <Ref. to RM-5, FLUID, 
RECOMMENDED MATERIALS, Recommend-
ed Materials.>

Fluid capacity:

0.8

6. POWER STEERING FLUID FOR LEAKS

Inspect the underside of oil pump and gearbox of
power steering system, hoses, pipes and their cou-
plings for fluid leaks.
If the fluid leaks are found, retighten their fitting
bolts (or nuts) and/or replace their parts.

NOTE:
• Wipe the leaked fluid off after correcting fluid
leaks.
• Also pay attention to clearances between hoses
(or pipes) and other parts when inspecting fluid
leaks.
