Hydraulic Power Steering

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 (slide plate, ripping plate, tilt pin) 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 assembly (Refer to Removal and Replacement ).
- If any excessive radial or axial free play on the steering wheel is found with the tilt lever in the lock position, always check the steering column assembly.

WARNING:

- If the vehicle continues to be driven after the collision absorbing mechanism has operated, the steering column shaft may be damaged while driving.
- If there is a slack in the slide plate, do not attempt to repair it. Replace the steering column assembly.

INSPECTION PROCEDURE

1. Remove the steering column covers (lower and upper).

CAUTION:
Do not release the tilt lever until the steering column has been installed.

2. Place the tilt lever in the locked position.

3. Loosen the two upper steering column mounting bolts by two turns.

4. Hold the steering wheel, and then try to rock it. If there is a radial or axial free play, replace the steering column assembly.





5. Check the tilt pin fixing detent of the lower bracket for deformation. If there is a deformation, replace the steering column assembly (Refer to Removal and Replacement).

CAUTION:

- Be careful that nothing is pinched between the slide plate and the body.
- Do not release the tilt lever until the steering column has been installed.

6. If no problem is found during the inspection, tighten the steering column assembly mounting bolts to the specified torque.
Tightening torque: 12± 2Nm (106± 17 in-lb)
