12. Apply recommended thread locking sealant to the thread (2
turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
13. Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.

of the rack assembly using the preload gauge [SST] and preload
adapter [SST]. Stop the gear at the point where highest torque is
read.
15. Loosen adjusting screw and retighten to 5.4 N·m (0.55 kg-m, 48
in-lb), and then loosen by 20 to 40°.
16. Measure pinion rotating torque using the preload adapter [SST]
and preload gauge [SST] to make sure that the measured value
is within the standard. Readjust if the value is outside the stan-
dard. Replace steering gear assembly if the value is outside the
standard after readjusting or adjusting screw rotating torque is 5
N·m (0.51 kg-m, 44 in-lb) or less.

gear housing assembly.
18. Set dial gauge as shown in the figure. Measure vertical move-
ment of rack assembly when pinion is turned clockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Readjust adjusting screw
angle if the measured value is outside the standard. Replace
steering gear assembly if the measured value is still outside the
standard or adjusting screw rotating torque is 5 N·m (0.51 kg-m,
44 in-lb) or less.
