Removal [08/2021 - 09/2022]: Procedure

1. When handling the rack and pinion power steering gear assembly:
   1. Do not subject the rack and pinion power steering gear assembly (especially the motor and torque sensor) to any impact. Replace the rack and pinion power steering gear assembly with a new one if subjected to a strong impact.
   2. Do not pull the wire harness when moving the rack and pinion power steering gear assembly.
   3. When the rack and pinion power steering gear assembly has been replaced, perform torque sensor zero point calibration.

      for A25A-FXS: Refer to CALIBRATION [06/2018 - ]

      for A25A-FKS, 2GR-FKS: Refer to CALIBRATION [06/2018 - ]

2. When disconnecting or reconnecting the connectors:
   1. Before disconnecting connectors related to the power steering system, turn the ignition switch to ON, center the steering wheel, turn the ignition switch off, and then disconnect the connectors.
   2. Before reconnecting connectors related to the power steering system, ensure that the ignition switch is off. Then center the steering wheel and turn the ignition switch to ON.
      NOTE:

      Do not turn the ignition switch to ON when the steering wheel is not centered.

   3. If the above operations are not carried out properly, the steering center point (zero point) will deviate, which may lead to a difference in steering effort between turning right and left.

      HINT: 

      If there is a difference in steering effort between turning right and left, perform torque sensor zero point calibration.

      for A25A-FXS: Refer to CALIBRATION [06/2018 - ]

      for A25A-FKS, 2GR-FKS: Refer to CALIBRATION [06/2018 - ]

1. Secure the steering wheel with the seat belt in order to prevent rotation.

   WARNING:

   Apply molybdenum grease to the threads and end of the SST bolt.

   NOTE:

   • Be sure to tighten the string firmly to secure SST to the steering knuckle LH to prevent SST from falling off.
   • Install SST with the center nut so that (A) and (B) shown in the illustration are parallel. Otherwise, the ball joint dust cover may be damaged.
   • Be sure to place the wrench on the part shown in the illustration.
   • Do not damage the front disc brake dust cover.
   • Do not damage the ball joint dust cover.
   • Do not damage the steering knuckle LH.
