REMOVAL AND INSTALLATION
| CAUTION | Before removing the steering wheel assembly and driver's air bag module, always refer to SERVICE PRECAUTIONS and AIR BAG MODULE AND CLOCK SPRING . After removing the steering wheel, always perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point. (Refer to STEERING WHEEL SENSOR CALIBRATION .) |
Scheme 14

Note. The special tool MB990784 can be inserted through the notch behind the area shown.
Scheme 15
<< B >> AIR BAG MODULE CONNECTOR CONNECTION REMOVAL
Slide the outer housing of the driver's air bag module connector in the arrow direction shown and disconnect the connector.
Scheme 16
<< C >> DRIVER'S AIR BAG MODULE REMOVAL
| CAUTION | Never use an electric tester to diagnose the air bag module circuit. Never attempt to disassemble the air bag module. Store the removed air bag module in a clean, dry place with the pad surface facing upward. When discarding the air bag module, deploy the air bag as specified in the service procedure. (Refer to AIR BAG MODULE DISPOSAL PROCEDURE .) With the driver's air bag module mounting torx screw, loosen the screw, but do not remove it. |
Using the torx wrench (T30), remove the driver's air bag module.
Scheme 17
Scheme 18
- Position the steering wheel in a straight ahead position. CAUTION: Use the special tool to remove the steering wheel since the steering column collision absorbing mechanism may be damaged.
- Use special tool MB990803 to remove the steering wheel.
>> A << STEERING WHEEL ASSEMBLY INSTALLATION
After centering the clock spring (Refer to DRIVER'S AIR BAG MODULE AND CLOCK SPRING ), install the steering wheel assembly.
>> B << AIR BAG MODULE CONNECTOR CONNECTION/AUDIO CONTROL SWITCH CONNECTOR CONNECTION/HORN CONNECTOR CONNECTION INSTALLATION
Connect the connector securely and route the harnesses not to lie off the cover hole.
| CAUTION | Before removing the steering wheel assembly and driver's air bag module/knee air bag module, always refer to SERVICE PRECAUTIONS and AIR BAG MODULE AND CLOCK SPRING or KNEE AIR BAG MODULE .) After installation, perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point. (Refer to STEERING WHEEL SENSOR CALIBRATION .) |
Scheme 19
<< A >> KNOB CAP REMOVAL
Remove the knob cap while pressing the two projections.
Scheme 20
- Remove the clip (for securing the floor carpet), and turn back the floor carpet.
- Remove the clip (for securing the steering shaft cover), and then remove the steering shaft cover.
<< A >> STEERING LOCK BOLT REMOVAL
- Use a drill to make a hole just deeply enough for the tap to stand on the steering lock bolt.
- Use a left-hand thread tap to remove the steering lock bolt.
Scheme 21
- When installing the steering lock assembly to the steering column shaft assembly, temporarily assemble the steering lock assembly while aligning it with the boss on the column.
- Make sure that the steering lock operates normally, and then tighten the steering lock bolt until its head is broken off.
| CAUTION | Before removing the steering wheel assembly and driver's air bag module, always refer to SERVICE PRECAUTIONS and AIR BAG MODULE AND CLOCK SPRING . Also, position the front wheels in a straight ahead direction. If you fail to do this, clock spring for SRS may get damage, making the SRS (air bag) inoperative, and it may cause a serious injury to the driver. * : Indicates the bolts and nuts with friction coefficient stabilizer. In removal, ensure there is no damage, clean dust and soiling from bearing and thread surfaces, and tighten them to the specified torque. After installation, perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point. (Refer to STEERING WHEEL SENSOR CALIBRATION ). |
Scheme 22
<< B >> SELF-LOCK NUT (TIE-ROD END AND KNUCKLE CONNECTION) REMOVAL
| CAUTION | Loosen the self-locking nut (tie-rod end connection) from the ball joint, but do not remove here. Use the special tool. To prevent the special tool from dropping off, suspend it with a rope. |
- Install special tool MB991897 or MB992011 as shown in the figure.
- Turn the bolt and knob to make the special tool jaws parallel, then hand-tighten the bolt. After tightening, check that the jaws are still parallel. NOTE: To adjust the special tool jaws to be parallel, set the orientation of the knob as shown in the figure.
- Unscrew the bolt to disconnect the ball joint.
<< C >> FRONT SUSPENSION CROSSMEMBER REMOVAL
- Jack up and support the crossmember, and remove it.
- Check the hoses and harnesses for roughness, and then remove the front suspension crossmember with the rear roll stopper and the steering gear and linkage installed.
>> A << JOINT COVER GROMMET INSTALLATION
Install by aligning the marks of joint cover grommet and steering gear and linkage as shown in the figure.
Scheme 23
>> B << Steering column bolt (connection of steering column shaft assembly and steering gear and linkage) installation
- While sliding shaft A from shaft B with the clip claw as shown in the figure being pinched, connect the steering column shaft assembly and the steering gear and linkage.
- Insert the steering column bolt from the no tapped bolt hole, and tighten it to the specified torque. Tightening torque : 20 ± 5 N.m (15 ± 3 ft-lb)
>> A << BAND INSTALLATION
| CAUTION | Secure the rack housing, and firmly crimp the bellows band by the bellows band clipping tool (special tool: MB992209). Crimp the bellows band securely until the special tool (MB992209) contacts the stopper. |
Scheme 24
Scheme 25
- Using the special tool (MB992209), crimp the bellows band.
- Check that the crimping width of the band (A) is within the range of the standard value. Standard value (A): 2.4 - 2.8 mm (0.09 - 0.11 in)
>> B << TIE-ROD END/LOCKING NUT INSTALLATION
Screw in the tie-rod to the length shown in the figure, and hand-tighten the locking nut.
Note. Install the steering gear and linkage to the body, adjust the toe-in, and then tighten the locking nut to the specified torque.
