NO: Go to Step 5.
STEP 5. Check for oil leaks.
Q: Are there oil leaks?
YES: Find the cause of the oil leakage and repair it. Then go to Step 9 .
NO: Go to Step 6.
STEP 6. Check the wheel alignment (camber and caster).
Refer to FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT
.
Q: Is the alignment incorrect?
YES: Adjust alignment. Then go to Step 9 .
NO: Go to Step 7.
STEP 7. Check the gear box rack piston seal for damage.
Q: Is there damage?
YES: Replace it. Then go to Step 9 .
NO: Go to Step 8.
STEP 8. Check for excessive tie rod end ball joint breakaway torque.
Refer to TIE ROD END BALL JOINT BREAKAWAY TORQUE
CHECK
.
Q: Is the breakaway torque out of specification?
YES: Replace the tie rod end. Then go to Step 9.
NO: Go to Step 9.
STEP 9. Check the steering wheel operation.
Verify that the steering wheel operation is not difficult.
Q: Is the steering wheel operation difficult?

wheel circumference and check the play.
Standard value (steering wheel play with the engine stopped): 10 mm (0.4
inch) or less
5. If the play exceeds the standard value, remove the steering gear (Refer to
POWER STEERING GEAR BOX AND LINKAGE
.) and check the total
pinion torque (Refer to STEERING GEAR TOTAL PINION TORQUE
CHECK
.).
STEERING ANGLE CHECK 1. Place the front wheel on a turnin
g radius
gauge an
d measure the steerin
g an
gle.
CAUTION: On vehicles with ASC, if the steering angle is
adjusted, always carry out steering wheel sensor
calibration (Refer to STEERING WHEEL SENSOR
CALIBRATION
). This is necessary because the
TCL/ASC-ECU should update the steering neutral
point.

3. Recheck the steering angle.
4. On vehicles with ASC, if the steering angle is adjusted, always carry out
steering wheel sensor calibration (Refer to STEERING WHEEL SENSOR
CALIBRATION
).
TIE ROD END BALL JOINT BREAKAWAY TORQUE CHECK Required Special Tools:
MB990326: Preload Socket MB991897: Ball Joint Remover
CAUTION:
Do not remove the nut from ball
joint. Loosen it

7. Install the tie rod end to the knuckle, then tighten a new self-locking nut to the
specified torque.
Tightening torque: 29 +/- 4 N.m (21 +/- 3 ft-lb)
STATIONARY STEERING EFFORT CHECK 1. With the vehicle sto
pped on a flat and
paved surface, turn the steerin
g wheel to
CAUTION: Always use a new ball joint nut, as it is a self-
locking nut.

5. If it is not within the standard value, replace the oil pump.
6. Check whether or not the hydraulic pressure is the standard value when no-
load conditions are created by fully opening the shut-off valve of the pressure
gauge.
Standard value: 0.8 - 1.0 MPa (116 - 145 psi)
7. If it is not within the standard value, the probable cause is a malfunction of the
oil line or steering gear, so check these parts and repair as necessary.
8. Turn the steering wheel all the way to the left or right; then check the retention
hydraulic pressure.
Standard value: 9.3 - 9.8 MPa (1,349 - 1,421 psi)
9. If not the standard value, overhaul or replace the steering gear. Remeasure
fluid pressure.
10. Remove special tools MB991548, MB990662 and MB991549, and then tighten
the pressure tube flare nut to the specified torque.
Tightening torque: 15 +/- 3 N.m (11 +/- 2 ft-lb)
11. Bleed the system (Refer to POWER STEERING SYSTEM AIR
BLEEDING
).
POWER STEERING PRESSURE SWITCH CHECK Required Special Tools:
MB990662: Power Steering Oil Pressure Gauge MB991548: Power Steering Oil Pressure Gauge Adapter (Pump Side) MB991549: Power Steering Oil Pressure Gauge Adapter (Hose Side)
1. Disconnect the pressure hose from the oil pump, and then connect the special
tools MB991548, MB990662 and MB991549.
2. Bleed air, and then turn the steering wheel several times while the vehicle is
not movin
g so that the tem
perature of the fluid rises to a
pproximatel
y 50 - 60°

5. Loosen the two lower steering column mounting bolts by two turns.
6. If there is any sign of looseness when the moveable bracket is moved back and
forth by hand, replace the steering column shaft assembly with a new one.
7. If no problem is found during the inspection, tighten the steering column
mounting bolts to the specified torque.
Tightening torque: 12 +/- 2 N.m (102 +/- 22 in-lb) STEERING WHEEL REMOVAL AND INSTALLATION Post-installation Operation

WHEEL BEARING END PLAY CHECK 1. Remove the caliper assembly, and suspend the caliper assembly with a wire
and remove the brake disc.
2. Fit the dial gauge as shown in the diagram and move the hub in the axial
direction to measure the play.
