Mitsubishi Outlander: Power Steering Gear Box and Linkage

REMOVAL AND INSTALLATION

CAUTION

• Before removing the steering wheel and driver's airbag module, refer to GROUP 52B − Service Precautions and Driver's Airbag Module and Clock Spring. Position the front wheels in a straight ahead direction. If you fail to do this, the clock spring for SRS may be damaged, making the SRS (air bag) inoperable which may cause serious injury to the driver.
• The bolts marked with * are coated with the friction coefficient stabilizer. When removed these parts, make sure that they are free of damage, remove any dust and dirt on the bearing surfaces and the threads, and tighten to the specified torque.
• After installation, perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point. <Vehicles with ASC>.

Removal steps

1. Steering gear and joint connecting bolt
2. Self-lock nut (Tie-rod end and knuckle connection)
3. Eye bolt
4. Pressure hose connection
5. Gasket
6. Return hose connection
7. Flanged nut
8. Engine rear roll stopper bracket connecting bolt
9. Front axle crossmember
10. Engine rear roll stopper
11. Heat protector
12. Joint cover grommet
13. Flanged bolt
14. Steering gear and linkage

Required Special Tools:

• MB991897 or MB992011: Ball joint remover

REMOVAL SERVICE POINTS

SELF-LOCK NUT (TIE-ROD END AND KNUCKLE CONNECTION) REMOVAL

CAUTION

• Loosen the self-lock nut (tie-rod end and knuckle connection) from the ball joint (Do not remove). Use the special tool for the self-lock nut removal.
• To prevent the special tool from dropping off, suspend it with a rope.

1. Install the special tool ball joint remover (MB991897 or MB992011) as shown in the figure.

2. 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.

3. Unscrew the bolt to disconnect the ball joint.

FRONT AXLE CROSSMEMBER REMOVAL

1. Jack up and support the crossmember, and remove it.

2. Check the hoses and harnesses for roughness, and then remove the front axle No.1 crossmember assembly with the rear roll stopper and the steering gear and linkage installed.

INSTALLATION SERVICE POINT

JOINT COVER GROMMET INSTALLATION

Install the joint cover grommet to the steering gear and linkage by aligning the mating marks as shown in the figure.

INSPECTION

PINION TOTAL ROTATION TORQUE CHECK

CAUTION Secure the steering gear & linkage to the special mounting point. Fixing the steering gear & linkage to another point could deform or damage the gear housing.

1. Use the preload socket (Special tool: MB991006) to rotate the pinion at a rate of one turn per 4 to 6 seconds, and then measure the pinion total rotation torque.

Standard value:
Total rotation torque: 0.6 - 1.6 N*m (5.3 - 14.2 in-lb)
Torque fluctuation: 0.4 N*m (3.5 in-lb) or less

NOTE:

• During measurement, remove the bellows from the gear housing.
• Rotate the pinion by 180º in left and right directions from the neutral position, and measure the pinion total rotation torque.

2. If the measurement value is outside the standard value, replace the gear housing.

DISASSEMBLY AND ASSEMBLY

Disassembly steps

1. Feed pipe
2. Jam nut
3. Tie-rod end
4. Clip
5. Band
6. Bellows
7. Tie-rod
8. Gear housing

Required Special Tool:

• MB992209: Boot band clipping tool

ASSEMBLY SERVICE POINTS

TIE-ROD INSTALLATION

CAUTION Do not tighten the vise strongly in order not to damage the rack bar.

1. Wrap rack bar with cloth in order not to damage, and tix the rack bar with a vise.

2. Use special tool variable spanner (MB992249) to tighten the tie-rod to the specified torque.

Tightening torque: 89 +- 9 N*m

BAND INSTALLATION

CAUTION

• Hold the rack housing, and use special tool bellows band crimping tool (MB992209) to crimp the bellows band securely.
• Crimp the bellows band until special tool (MB992209) touches the stopper.

1. Use special tool boot band crimping tool (MB992209) to crimp the bellows band.

2. Check that crimped width (A) is within the standard value.

Standard value (A): 2.4 − 2.8 mm

TIE-ROD END/JAM NUT INSTALLATION

Screw in the tie-rod to the length shown in the figure, and hand-tighten the jam nut.

NOTE: Install the steering gear and linkage to the body, adjust the toe-in, and then tighten the jam nut to the specified torque.
