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.
17. Apply recommended Liquid Gasket to inner socket and turn pin-
ion fully to left with inner socket installed to gear housing assembly.
18. Set dial indicator 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 in-lb). Readjust adjusting
screw angle if the measured value is outside the standard.
Replace 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.
19. Install large end of boot to gear housing assembly.
20. Install small end of boot to inner socket boot mounting groove.
21. Install boot clamp to boot small end.
22. Install large side of boot clamp.

Tighten large side of boot with boot clamp (stainless wire).

Wrap clamp around boot groove for two turns. Insert a flat-
bladed screwdriver in loops on both ends of wire. Twist 4 to
4.5 turns while pulling them with force of approximately 98 N
(10 kg, 22 lb).

Twist boot clamp as shown. Pay attention to relationship
between winding and twisting directions.

Twisted point of clamp is in the opposite side of adjusting
screw as shown in the figure (to prevent contact with other
parts).

Bend cut end of the wire toward rack axial as shown in the fig-
ure after twisting the wire 4 to 4.5 turns so that cut end does
not contact with boot.
CAUTION:
Keep gap from cylinder tube 5 mm (0.20 in) or more.
23. Install cylinder tubes to gear housing assembly.
24. Adjust inner socket to standard length L, and then tighten lock
nut to the specified torque. Refer to PS-20, "
COMPONENTS" .
Check length of inner socket L again after tightening lock nut .
Make sure that the length is the standard.
CAUTION:
Adjust toe-in after this procedure. Length achieved after
toe-in adjustment is not necessary the above value.
