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 m m
(±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:
132 - 308 N (13.5 - 31.4 kg, 30 - 69 lb)
Maximum force deviation:
176 N (17.9 kg, 39 lb)
12. If rack sliding force is not within specification, readjust by
repeating adjustment procedure from the beginning.
13. If rack sliding force is still out of specification after
readjustment, gear assembly needs to be replaced.

AssemblyNJST0043Assemble oil pump, noting the following instructions.
Make sure O-rings and oil seal are properly installed.
Always install new O-rings and oil seal.
Be careful of oil seal direction.
Cam ring, rotor and vanes must be replaced as a set if neces-
sary.
Coat each part with DEXRON
