11. Apply thread locking adhesive (Three Bond 1111B or equivalent)
to the thread of adjusting screw to the adjusting screw height
from gear housing assembly. The adjusting 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 4.9 - 5.9 N·m (0.50 - 0.60 kg-m, 44 - 52 in-lb). After that
loosen it within from 20° to 40°.
15. Measure pinion rotating torque with torque adapter (SST) and
preload gauge (SST), then confirm whether its 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 (0.51kg-m, 44 in-lb)
16. Turn pinion fully to the end of the left with tie-rods to rack.
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.
