20. Before installing boot, coat the contact surfaces between boot
and tie-rod with grease.
SST440A
21. Install boot clamps.
I
To install, wrap boot clamp around boot groove twice. To
tighten clamp, place a screwdriver through both rings. Twist

Adjustment
NCST0026
Adjust pinion rotating torque as follows:
1.
Set rack to the neutral position without fluid in the gear.
2.
Coat the adjusting screw with locking sealant and screw it in.
3.
Lightly tighten lock nut.
4.
Tighten adjusting screw to a torque of 4.9 to 5.9 N·m (50 to 60
kg-cm, 43 to 52 in-lb).
5.
Loosen adjusting screw, then retighten it to 0.2 N·m (2 kg-cm,
1.7 in-lb).
SST718CB
6.
Move rack over its entire stroke several times.
7.
Measure pinion rotating torque within the range of 180° from
neutral position.
Stop the gear at the point of maximum torque.
8.
Loosen adjusting screw, then retighten it to 4.9 N·m (50 kg-cm,
43 in-lb).
9.
Loosen adjusting screw by 70° to 110°.
SST713C
10. Prevent adjusting screw from turning, and tighten lock nut to
specified torque.

11. Check rack sliding force on vehicle as follows:
a.
Install steering gear onto vehicle, but do not connect tie-rod to
knuckle arm.
b.
Connect all piping and fill with steering fluid.
c.
Start engine and bleed air completely.
d.
Disconnect steering column lower joint from the gear.
e.
Keep engine at idle and make sure steering fluid has reached
normal operating temperature.
f.
Pull tie-rod slowly to move it from neutral position to
±
11.5 mm
(
±
0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
167 - 226 N (17 - 23 kg, 37 - 51 lb)
Maximum force deviation:
98 N (10 kg, 22 lb)
g.
Check sliding force outside above range at rack speed of 40
mm (1.57 in)/s.
Maximum rack sliding force:
294 N (30 kg, 66 lb)
Maximum force deviation:
147 N (15 kg, 33 lb)
