  1. Before servicing the vehicle, refer to the Precautions Section.
    CAUTION
    The spiral cable may snap due to steering operation if the steering column is separated from the steering gear assembly. Therefore fix the steering wheel with a string to avoid turning too far.

  2.  
  3. Set the wheels in the straight-ahead position.
  4.  
  5. Raise and safely support the vehicle.
  6.  
  7. Remove the tires from vehicle.
  8.  
  9. Remove the undercover.
  10.  
  11. Confirm the slit of the lower joint fits with the projection on the rear cover cap, furthermore marking position on steering gear assembly nearly fits with the projection on rear cover cap.
  12.  
  13. Remove the cotter pin at steering outer socket, then loosen the mounting nut.
  14.  
  15. Use a ball joint remover to remove the steering outer socket from the steering knuckle. Be careful not to damage the ball joint boot.
    CAUTION
    Temporarily tighten the mounting nut to prevent damage to the threads and to prevent the ball joint remover from coming off.

  16.  
  17. Remove the high pressure side and low pressure side oil pipes from the steering gear assembly, then drain the fluid from the pipes.
  18.  
  19. Remove the mounting bolt of the steering hydraulic pipe bracket from the steering gear assembly.
  20.  
  21. Remove the lower side mounting bolt of the lower joint.
  22.  
  23. Remove the mounting bolts of the steering gear assembly, then remove the steering gear assembly from the vehicle.
  24.  

To install:

  1. Installation is the reverse of the removal procedure.
    NOTE
    Refer to component parts location and do not reuse non-reusable parts.

  2.  
  3. After installation, check wheel alignment.
  4.  
  5. After adjusting wheel alignment, adjust the neutral position of the steering angle sensor.
  6.  
  7. When steering wheel is set in the straight ahead direction, confirm the slit of the lower joint fits with the projection on the rear cover cap, and that the marking position on steering gear assembly nearly fits with the projection on rear cover cap.
  8.  
  9. Bleed all air from the power steering system, as follows:
  10.  

Incomplete air bleeding causes the following. When this happens, bleed the system again:



Generation of air bubbles in the reservoir tank.
 
Generation of clicking noise in the oil pump.
 
Excessive buzzing in the oil pump.
 


NOTE
When the vehicle is stationary or while the steering wheel is being turned slowly, some noise may be heard from the oil pump or gear. This noise is normal and does not affect any system.

  1. Stop the engine, then turn the steering wheel fully to the right and left several times.
    CAUTION
    Do not allow the steering fluid reservoir tank level to drop below the low-level line. Check the tank frequently and add fluid as needed.

  2.  
  3. Run the engine at idle speed. Turn the steering wheel fully to the right and then fully to the left, and keep hold for about three seconds. Then check whether any fluid leaks have occurred.
  4.  
  5. Repeat sub-step b several times at about three second intervals.
    CAUTION
    Do not hold the steering wheel in the locked position for more than 10 seconds. (There is the possibility that the oil pump may be damaged.)

  6.  
  7. Check for air bubbles and cloudiness in the fluid.
  8.  
  9. If air bubbles and/or cloudiness don't fade, stop the engine, and stop air bleeding until the air bubbles and cloudiness fade.
  10.  
  11. Perform until all bubbles and cloudiness are gone.
  12.  
  13. Stop the engine and check the fluid level.
  14.  

  1. Check that the steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
  2.
