Steering Gear: Testing and Inspection

STEERING GEAR / LINKAGE: STEERING GEAR: INSPECTION; 2013 MY FR-S [03/2012 -]

1. INSPECT TIE ROD END SUB-ASSEMBLY

(a) Secure the tie rod assembly in a vise.

NOTICE:
Do not overtighten the vise.

(b) Turn the ball joint back and forth.

OK:

There is no unusual resistance or play while turning.

HINT
* If the result is not as specified, remove the tie rod end sub-assembly with a new one.
* If the dust seal is fissured, damaged or deteriorated, replace it with a new one.

2. INSPECT TOTAL PRELOAD

NOTICE:
Inspect the total preload in a no-load condition by removing the tie rod assembly RH and LH, and steering rack boots.

(a) Install SST to the pinion shaft and turn it left and right 5 times or more.

SST : 09616-00011





(b) Set a torque wrench to SST and turn the pinion shaft continuously at a rate of 4 to 6 seconds per turn to inspect the total preload of the steering gear assembly.

Standard Preload:

0.9 to 1.6 N*m (9.2 to 16.3 kgf*cm, 8.0 to 14.2 in.*lbf)

NOTICE:
Inspect the total preload around the steering rack center position.

HINT
If the total preload is not within the specified range, adjust the total preload.

3. ADJUST TOTAL PRELOAD

(a) Temporarily install the rack ends sub-assembly RH and LH.

(b) Install the steering rack guide and steering rack guide spring to the steering rack housing.

(c) Apply the three bond to the screw part of steering rack guide spring cap and steering rack housing.

(d) Temporally install the steering rack guide spring cap.

(e) Using SST, tighten the steering rack guide spring cap so that the rotational torque of the pinion shaft reaches the standard value.

SST : 09616-00011

Torque: Preload (turning):

0.9 to 1.6 N*m (9.2 to 16.3 kgf*cm, 8.0 to 14.2 in.*lbf)

(f) Apply the three bond to the screw part of lock nut.

(g) Using SST, hold the steering rack guide spring cap and tighten the lock nut.





SST : 09631-10021

SST : 09922-10010

Torque : 60 Nm (612 kgf-cm, 44 ft-lbf)

NOTICE:
* Use the formula to calculate special torque values for situations where SST is combined with a torque wrench Service Precautions.
* Turn SST in the direction as shown in the illustration.

(h) Set a torque wrench to SST and turn the pinion shaft continuously at a rate of 4 to 6 seconds per turn to inspect the total preload of the steering gear assembly.

SST : 09616-00011

Standard Preload:

0.9 to 1.6 N*m (9.2 to 16.3 kgf*cm, 8.0to 14.2 in.*lbf)

NOTICE:
Inspect the total preload around the steering rack center position.
