9. Use a rear cover wrench (SST), install rear cover to gear housing assembly.
10. Confirm projection on rear cover cap nearly fit with marking position on gear housing assembly.
11 . A p p l y t h r e a d l o c k i n g a d h e s i v e ( T h r e e B o u n d T B 1111 B o r e q u i v - alent. Refer to GI-48
) to the thread of adjusting screw to the
adjusting screw height from gear housing assembly. The adjust-
ing screw height is the same as it was measured in the overhaul
in advance.
12. Rotate pinion ten times whole range of rack so that parts get to fit with each other.
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 whether it's reading is within
the specified value. If the reading is not within the specified
value, readjust screw angle with adjusting screw. Change gear
assembly to new one, if the reading 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.

Pinion rotating torque:
Around neutral position (within ±100 °)
Average “A”:
0.8 − 2.0 N·m (0.08 − 0.20 kg-m, 7 − 18 in-lb)
Other than above (more than ±100 °)
Maximum variation “B”:
2.3 N·m (0.23 kg-m, 20 in-lb)
