INSPECTION AFTER DISASSEMBLY
Boot
Check boot for cracks and deformation. Replace it, if necessary.
Rack
Check rack for damage and wear. Replace it, if necessary.
Sub-Gear Assembly
Check pinion gear for damage and wear. Replace it, if necessary.
Check bearing while rotating it. Replace bearing if bearing ball race was dented, worn, or damaged.
Gear Housing Assembly
Check gear housing assembly for damage and scratches (inner wall). Replace it, if necessary.
Outer Socket and Inner Socket
Swing Torque
Hook a spring balance at the point shown in the figure. Confirm
if the reading is within the specification. When ball stud and
inner socket start moving the measured value must be within the
specification. If the reading is outside the specification, replace
socket.
Rotating Torque
Using a preload gauge (SST), check if reading is within the
value specified below. If the value is outside the standard,
replace outer sockets.

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.

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.
