13. Measure pinion rotating torque within from –180 ° to +180 °,
make preload gauge (SST) and torque adapter (SST) in rack
neutral position, then hold preload gauge (SST) at maximum
torque.
14. After loosening adjusting screw once, tighten it again with torque of 5.4 N·m (0.55 kg-m, 48 in-lb). After that loosen it within 20 ° to
40 °.
15. Measure pinion rotating torque with torque adapter (SST) and preload gauge (SST), then confirm w hether it's reading is within
the specified value. If the r eading is not within the specified
value, readjust screw angle with adjusting screw. Change gear
assembly to new one, if the readi ng is still not within the speci-
fied value or the rotating torque of adjusting screw is less than 5
N·m (0.51 kg-m, 44 in-lb).
16. Turn pinion fully to the end of the left with inner socket to gear housing assembly.
17. Set dial gauge to rack as shown in the figure. Measure vertical movement of rack when pinion is turned counterclockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Check reading is within
the specified value. If reading is outside of the specification,
readjust screw angle with adjusting screw. If reading is still out-
side of specification, or if the rotating torque of adjusting screw is
less than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear
assembly.
18. Install large-diameter side of boot to gear housing assembly.
19. Install small-diameter side of boot to the mounting groove of inner socket boot.
20. Install boot clamp to the small-diameter side of boot.
21. Install boot clamp to the large-diameter side of boot.

Pinion rotating torque:
Around neutral position (within ±100 °)
Average “A”:

Other than above (more than ±100 °)
Maximum variation “B”:
2.3 N·m (0.23 kg-m, 20 in-lb)
