6. Move rack over its entire stroke several times.
7. Measure pinion rotating torque within the range of 180É from
neutral position.
Stop the gear at the point of maximum torque.
8. Loosen adjusting screw, then retighten it to 4.9 to 5.9 N´m (50
to 60 kg-cm, 43 to 52 in-lb).
9. Loosen adjusting screw by 10É to 20É.

10. Prevent adjusting screw from turning, and tighten lock nut to
specified torque.

11. Measure pinion rotating torque.
Lock to lock:
Average rotating torque
0.78 - 1.47 N´m (8.0 - 15.0 kg-cm, 6.9 - 13.0 in-lb)
Within±100É from the neutral position:
Maximum torque variation
0.4 N´m (4 kg-cm, 3.5 in-lb)
Outside the above range:
Maximum force variation
0.6 N´m (6 kg-cm, 5.2 in-lb)
IIf pinion rotating torque is not within specifications, readjust it
starting from step 4. If pinion rotating torque is still out of
specifications after readjustment, replace steering gear
assembly.

12. 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.
