CHASSIS AND BODY MAINTENANCE

Checking Power Steering Fluid and LinesBLS00063
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80°C (122 to 176°F)
or “COLD” range at fluid temperatures of 0 to 30°C (32 to 86°F).
CAUTION:

Do not overfill.

Recommended fluid is DEXRONTM III type ATF or equiva-
lent.
Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsBLS00064
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelBGS0003P

Check fluid level with the engine stopped.

Make sure that fluid level is between MIN and MAX.

Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:

The fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.

Do not reuse drained power steering fluid.
Checking Fluid LeakageBGS0003Q
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80°C
(122 to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully, check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-29, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid, indicating from steering gear.
Air Bleeding Hydraulic SystemBGS0003R
If air bleeding is not complete, the following symptoms can be observed.

Bubbles are created in reservoir tank.

Clicking noise can be heard from oil pump.

Excessive buzzing in oil pump.
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of
the system.
1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Filling reservoir tank with fluid so as not to lower fluid level below the MIN line while steering
wheel turning.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and white contamination.
5. Stop engine if bubbles and white contamination do not drain out. Perform steps 2 to 3 above after waiting
until bubbles and white contamination drain out.HOT : Fluid temperature 50 – 80°C (122 – 176°F)
COLD : Fluid temperature 0 – 30°C (32 – 86°F)

STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceBGS0003S
CHECKING CONDITION OF INSTALLATION

Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check steering gear assembly mounting nut and bolts for looseness. Refer to PS-17, "COMPONENTS" .
CHECKING STEERING WHEEL PLAY

Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.

When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of power steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL

Make sure that steering gear assembly, steering column and steering wheel are installed in the correct
position.

Perform neutral position inspection after wheel alignment. Refer to FSU-5, "Wheel Alignment Inspection" .

Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80°C (122 to 176°F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-29,
"CHECKING RELIEF OIL PRESSURE" .
a. Disconnect lower shaft and steering knuckle from steering gear assembly. Refer to FAX-5, "
COMPO-
NENT" , PS-12, "COMPONENTS" .
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 – 35 mm (0 – 1.38 in)
Steering wheel turning force
: Less than 45 N (4.6 kg, 10 lb)

POWER STEERING GEAR AND LINKAGE

7. Remove high-pressure tube and low-pressure hose of hydraulic
piping, and then drain power steering fluid. Refer to PS-39,
"HYDRAULIC LINE" .
8. Remove fixing bolt (lower side) of lower shaft.
9. Remove mounting nut and bolts and remove rack mounting
bracket, rack mounting insulator and sleeve from vehicle, and
then remove steering gear assembly from vehicle.
QR20DE Models
1. Set vehicle to the straight-ahead position.
2. Remove the clip, then remove lower cover.
3. Remove fixing nut and bolt, then separate lower shaft from
steering column assembly (joint part).
4. Remove tyres from vehicle.
5. Remove undercover and splash guard.
6. Remove cotter pin of steering outer socket and steering knuckle
mounting point, and then loosen the nut.
7. Remove steering outer socket from steering knuckle so as not to
damage ball joint boot using the ball joint remover (suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover from suddenly coming
off.

Installation is the reverse order of removal. For tightening torque, refer to PS-17, "COMPONENTS" .

When installing lower shaft to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn pinion assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(C) is aligned with both the projection (A) of rear cover cap (1)
and the marking position (B) of gear housing assembly.
–After installation, bleed air from the steering hydraulic system.
Refer to PS-39, "
HYDRAULIC LINE" .
–Perform final tightening of nuts and bolts on each part under
unladen conditions with tyres on level ground when removing
steering gear assembly. Check wheel alignment. Refer to FSU-
5, "Wheel Alignment Inspection" .
–Adjust neutral position of steering angle sensor after checking the wheel alignment for the models with
VDC. Refer to BRC-40, "
