Steering Gear: Testing and Inspection
Inspection1. Inspect the tie-rod end SUB-ASSY LH.
(1) Secure the tie-rod ASSY LH wheel joint part in a vise between aluminum plates.
CAUTION:
Do not close the vise too strongly.
(2) Swing and rotate the wheel joint.
Criteria: There is no abnormal sticking or looseness during swing and rotation.
NOTE:
^ If the criteria is not satisfied, replace the tie-rod end SUB-ASSY LH with a new part.
^ If you notice any dust seal cracks, damage, or deterioration, replace the tie-rod end SUB-ASSY LH with a new part.
2. Inspect the tie-rod end SUB-ASSY RH.
NOTE:
Perform the same procedure on the RH side as with the LH side.
3. Inspect the total preload.
(1) To prevent steering rack overstroke, temporarily fit the left and right steering rack ends.
(2) Use a SST to rotate the pinion shaft at a rate of 1 revolution every 3 to 5 seconds, and check steering gear ASSY total preload.
SST 09616-00011
Standard value:T=0.9 - 1.6Nm {9.2 - 16.3kgf-cm} {0.66 - 1.18 ft-lbf} (While rotating)
CAUTION:
^ Perform the check at the steering rack neutral position.
^ Be careful not to move the steering rack the full stroke.
NOTE:
If it is not within the specified value, adjust the total preload.
4. Adjust the total preload.
(1) Use a SST to remove the lock nut.
SST 09922-10010
CAUTION:
Be sure to only use SSTs in the correct direction.
(2) Use a SST to remove the steering rack guide spring cap.
SST 34299CA000
(3) Clean the threaded portion of the steering rack housing and the steering rack guide spring cap, and remove any oil with white gasoline.
(4) Apply Three Bond 1141G or Three Bond 1102 to the threaded portion of the steering rack guide spring cap, and temporarily tighten it.
(5) To ensure that the steering control valve rotational torque is at the specified value, use a SST to tighten the steering rack guide spring cap.
SST 34299CA000, 09616-00011
Standard value:T=0.9 - 1.6Nm {9.2 - 16.3kgf-cm} {0.66 - 1.18 ft-lbf} (While rotating)
(6) Clean the threaded portion of the lock nut and remove any oil with white gasoline.
(7) Apply Three Bond 1141G or Three Bond 1102 to the threaded portion of the lock nut.
(8) Secure the steering guide spring cap and tighten the lock nut with a SST.
SST 09922-10010, 34299CA000
Standard value:T=60Nm {612kgf-cm} {44.3ft-lbf}
CAUTION:
^ When you connect a torque wrench to the SST and tighten it while it is extended the total length, continuing until the torque wrench reading reaches the prescribed value will result in the actual tightening torque being larger than desired.
^ Be sure to only use SSTs in the correct direction.
(9) Use a SST to rotate the pinion shaft at a rate of 1 revolution every 3 to 5 seconds, and check steering gear ASSY total preload.
SST 09616-00011
Standard value:T=0.9 - 1.6Nm {9.2 - 16.3kgf-cm} {0.66 - 1.18 ft-lbf} (While rotating)
CAUTION:
^ Perform the check at the steering rack neutral position.
^ Be careful not to move the steering rack the full stroke.
^ After the inspection is completed, set it back to the neutral position.
