2. Bleed air, then turn the steering wheel several times while the vehicle is not
moving so that the temperature of the fluid rises to approximately 50 - 60°C
(122 - 140°F).
3. Start the engine and idle it at 700 +/- 100 r/min.
4. Fully close the shut-off valve of the pressure gauge and measure the oil pump
relief pressure to confirm that it is within the standard value range. Open it
again immediately after checking the pressure.
Standard value: 9.3 - 9.8 MPa (1,349 - 1,421 psi)
CAUTION: The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.

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

C (122 - 140°F).
3. The engine should be idling.
4. Disconnect the connector for the oil pressure switch, and place an ohmmeter at
the switch.
5. Gradually close the shut-off valve of the pressure gauge and increase the
hydraulic pressure, then check whether or not the hydraulic pressure that
activates the switch is the standard value.
Standard value: 18 - 2.4 MPa (261 - 348 psi)
6. Gradually open the shut-off valve and reduce the hydraulic pressure; then
check whether or not the hydraulic pressure that deactivates the switch is the
standard value.
Standard value: 0.8 - 2.4 MPa (116 - 348 psi)
7. Remove the 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)
8. Bleed the system. (Refer to POWER STEERING SYSTEM AIR BLEEDING
).

1. Press the dust cover with your finger to check whether the dust cover is
cracked or damaged.
2. If the dust cover is cracked or damaged, replace the tie rod end. STEERING COLUMN SHAFT ASSEMBLY SHOCK ABSORBING MECHANISM CHECK
If a collision occurs or severe impact is applied to the steering wheel, the
collision energy absorbing mechanism (one-way capsule) may have operated.
Once the mechanism has operated, it will be inoperative even if there is no
apparent damage. Determine if the steering column shaft can be reused by the
following procedure. If the collision energy absorbing mechanism has already
operated, replace the steering column shaft assembly. If any excessive radial free play on the steering wheel is found with the tilt
lever in the lock position, always check the steering shaft assembly.
INSPECTION PROCEDURE 1. Remove the lower and upper column covers.
2. Place the tilt lever in the locked
position.
NOTE: If the dust cover is cracked or damaged, the ball joint
could be damaged.
WARNING:
1. If the vehicle continues to be driven after the
collision absorbing mechanism has operated,
the steering column shaft may be damaged
while driving.
2. If there is a slack in the one-way capsule, do not
attempt to repair it. Replace the steering column
shaft assembly.
CAUTION: On completion, do not release the tilt lever until
the steering column has been installed.

3. Loosen the two upper steering column mounting bolts by two turns.
4. Hold the one-way capsules as shown in illustration, and then try to rock them.
If there is a slack in either of the capsules, replace the steering column shaft
assembly.
CAUTION:
1. Be careful that nothing is pinched between
the one-way capsules and the body.
2. On completion, do not release the tilt lever
until the steering column has been installed.

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
