STEERING SYSTEM (POWER STEERING)
(2) Retighten the adjusting screw to 7.4 N·m
(0.75 kgf-m, 5.4 ft-lb) and back off 25
°
.
(3) Apply liquid packing to at least 1/3 of entire
perimeter of adjusting screw thread.
(4) Install the lock nut. While holding the adjust-
ing screw with a wrench, tighten the lock nut us-
ing ST.
ST 926230000 SPANNER
Tightening torque (Lock nut):
39 N·m (4.0 kgf-m, 29 ft-lb)
Hold the adjusting screw with a wrench to pre-
vent it from turning, while tightening the lock nut.
4. TIE-ROD
1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.
2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If the castle nut is loose, re-
tighten it to the specified torque, then tighten further
up to 60
°
until the cotter pin hole is aligned.
Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)
3) Check the lock nut on tie-rod end for tightness. If
it is loose, retighten it to the specified torque.
Tightening torque:
83 N·m (8.5 kgf-m, 61.5 ft-lb)
5. POWER STEERING FLUID LEVEL
NOTE:
• Check at power steering fluid temperature 20
°
C
(68
°
F); read the fluid level on the “COLD” side.
• Check at power steering fluid temperature 80
°
C
(176
°
F); read the fluid level on the “HOT” side.
1) Place the vehicle with engine “OFF” on a flat and
level surface.
2) Check the fluid level using the scale on the out-
side of reservoir tank (A). If the level is below “MIN”
(B), add fluid to bring it up to “MAX” (C).
NOTE:
If the fluid level is at MAX level or above, drain fluid
to keep the level in specified range of indicator by
using a syringe or the like.
Recommended fluid:
Dexron III
Fluid capacity:
0.7
2
(0.7 US qt, 0.6 Imp qt)
6. POWER STEERING FLUID FOR LEAKS
Inspect the underside of oil pump and gearbox for
power steering system, hoses, piping and their
couplings for fluid leaks.
If fluid leaks are found, correct them by retightening
their fitting bolts (or nuts) and/or replacing their
parts.
NOTE:
• Wipe the leakage fluid off after correcting fluid
leaks, or a wrong diagnosis is taken later.
• Also pay attention to clearances between hoses
(or pipings) and other parts when inspecting fluid
leaks.
