STEERING WHEEL FREE PLAY CHECK

1. With the engine running (hydraulic pressure applied), position the front wheel in the straight ahead position.
2. Measure the side to side steering wheel play until the front wheels actually start moving while turning the steering wheel slightly in the left and right directions. Limit: 30 mm (1.2 inch)
3. If the steering wheel play exceeds the limit value, check the steering shaft joint or steering linkage for looseness, and replace or repair the faulty components if necessary.
4. If the steering wheel play still exceeds the limit value after Step 3 is performed, position the steering wheel in the straight ahead position, and then apply the force (approximately 5 N) in the circumferential direction. Standard value (steering wheel play with the engine stopped): 16.5 mm (0.6 inch) or less
5. If the steering wheel play is outside the standard value after Step 4 is performed, remove the steering gear and linkage, and check and adjust the pinion total rotation torque. (Refer to «POWER STEERING GEAR BOX AND LINKAGE»(ref-289393-S07120845202008063000000) ).

STEERING ANGLE CHECK

Scheme 51

1. Check that the wheel alignment is normal. (Refer to «WHEEL ALIGNMENT CHECK AND ADJUSTMENT»(ref-289415-S07006713702008063000000) .)
2. Place the front wheel onto the turning radius gauge, and measure the steering angle. Standard value: ITEM SPECIFICATIONS Item Specifications Inside wheel 33°10' ± 1°30' Outside wheel (reference value) 28°10'
3. If the measured value is not within the standard value, adjust the tie-rod ends (right and left), and repeat Steps 1 and 2 .
4. If the measured value is not within the standard value after performing Step 3 , replace the steering gear and linkage assembly. (Refer to «POWER STEERING GEAR BOX AND LINKAGE»(ref-289393-S07120845202008063000000) .)

TIE ROD END BALL JOINT DUST COVER CHECK

1. Using your fingers, press the dust cover to check for cracks or damage.
2. If there are any cracks in the dust cover or it is damaged, replace the tie-rod end (Refer to «DISASSEMBLY AND REASSEMBLY»(ref-289393-S13717458432008063000000) ). NOTE: If the dust cover has a crack or damage, the ball joint could be damaged.

STATIONARY STEERING EFFORT CHECK

1. Park the vehicle on a level paved road, position the steering wheel in the straight ahead position.
2. Start the engine, and maintain the engine speed at 1000 ± 100 r/min.
3. Position the spring scale on the circumference of the steering wheel, and measure the steering force at the time when the steering wheel is turned to right or left side (within the range of one and a half turns) from the center position. Standard value: Steering force: 32 N (7.2 lb) or less Fluctuation band: 5.9 N (1.33 lb) or less
4. If not within the standard value, check and adjust the suspected components.

STEERING WHEEL RETURN TO CENTER CHECK

Conduct a road test

Scheme 52

1. Make both gradual and sudden turns and check the steering wheel return.
2. At a vehicle speed of approximately 35 km/h (22 mph), turn the steering wheel 90 degrees, hold a few seconds, then release. If the steering wheel then returns 70 degrees or more, the return can be judged satisfactory. NOTE: There will be a momentary feeling or "heaviness" when the wheel is turned quickly, but this is not abnormal (Oil pump discharge amount is especially apt to be insufficient during idling).

POWER STEERING SYSTEM AIR BLEEDING

Perform air bleeding procedure as necessary after replacing the steering gear or the steering fluid lines.

Scheme 53

1. Raise and support the front wheels.
2. Disconnect the crank angle sensor connector. CAUTION: Perform air bleeding only while cranking the engine. If air bleeding is performed while the engine is running, air could enter the fluid. During air bleeding, refill the steering fluid supply so that the level never falls below the lower mark on the dipstick.
3. Turn the steering wheel all the way to the left and right five or six times while using the starter motor to crank the engine intermittently several times (for 15 to 20 seconds).
4. Connect the crank angle sensor connector.
5. Start the engine (idling).
6. Turn the steering wheel to the left and right until there are no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the level is between the high and low dipstick marks.
8. Confirm that there is very little change in the fluid level when the steering wheel is turned left and right. CAUTION: If the fluid level rises suddenly after the engine is stopped, the air has not been completely bled. If air bleeding is not complete, there will be abnormal noises from the pump and the flow-control valve, and this condition could cause reduce the life of the power steering components.
9. Confirm that the change in the fluid level is no more than 5 mm (0.2 inch) when the engine is stopped and when it is running.
10. If the change of the fluid level is 5 mm (0.2 inch) or more, the air has not been completely bled from the system. The air bleeding procedure must be repeated.
11. Use the scan tool MB991958, check if the DTC is set. If it is set, erase it.

POWER STEERING PRESSURE SWITCH CHECK

Required Special Tools

1. MB990662: Power Steering Oil Pressure Gauge
2. MB991548: Power Steering Oil Pressure Gauge Adapter (Pump Side)
3. MB991549: Power Steering Oil Pressure Gauge Adapter (Hose Side)

Scheme 54

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 moving so that the temperature of the fluid rises to approximately 50°C - 60°C (122°F - 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: 8.1 - 8.8 MPa (1,174 - 1,276 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: 8.1 - 8.8 MPa (1,174 - 1,276 psi)
7. Remove special tools MB991548, MB990662 and MB991549, connect the pressure hose to the oil pump, and then tighten the eye bolt to the specified torque. Tightening torque: 57 ± 7 N.m (42 ± 5 ft-lb)
8. Bleed the system. (Refer to «POWER STEERING SYSTEM AIR BLEEDING»(ref-289393-S36595281412008063000000) ).
