POWER STEERING GEAR AND LINKAGE

19. Use preload gauge (SST) and torque adapter (SST). Measure
pinion rotation torque within ±180° of neutral position of the gear.
Stop the gear at the point where highest torque is read.
20. Loosen adjusting screw and retighten to 4.9 - 5.9 N·m (0.50 -
0.60 kg-m, 44 - 52 in-lb), and then loosen by 60 - 80°(140-
176°F).
21. With adjusting screw held in place, tighten lock nut to 40 - 58
N·m (4.0 - 6.0 kg-m, 29 - 43 ft-lb).
22. Using a preload gauge (SST), measure rotating torque of pinion
gear. Check that reading is within range specified. If reading is
outside specification, readjust rack. If reading is still outside
specification, replace power steering gear.
23. With tie rod gear installed to gear assembly, turn pinion gear
fully to left.
24. Set dial gauge as shown in figure. Measure vertical movement
of rack when pinion is turned counterclockwise with torque of 4.9
N·m (0.5 kg-m, 43 in-lb). Check reading is within range speci-
fied. If reading is outside of specification, readjust rack. If read-
ing is still outside of specification, replace power steering gear.
25. Position boot band on large-diameter side before installing it.
26. Install small-diameter side of boot to inner socket boot mounting
groove.
27. Install boot band to small-diameter side of boot.

28. Install boot clamp.
a. Tighten large-diameter side of RH/LH boot with boot clamp
(stainless wire).
b. Wrap clamp around boot groove for two turns. Insert screwdriv-
ers in loops on both ends of wire. Twist 4 to 4.5 turns while pull-
ing them with force of approx. 98 N (10 kg, 22.1 lb).
c. Twist boot clamp as shown. Pay attention to relationship
between winding and twisting directions.
d. Twisted point should face front of vehicle with gear installed on
vehicle (to prevent interference with other parts).
e. After twisting wire 4 to 4.5 turns, bend cut end of wire. Cut end of
wire should not touch boot. Be sure wire end is at least 5 mm
(0.20 in) away from clearance for tube.
29. Connect lock nut and outer socket to inner socket. Temporarily
tighten lock nut until length of tie rod is within specification.
CAUTION:
Perform toe-in adjustment after this procedure. Length
achieved after toe-in adjustment is not necessarily value
given here.Wire length ( ): 370 mm (14.57 in)
