4. FULLY TIGHTEN SHOCK ABSORBER ASSEMBLY
REAR LH
(a) Stabilize the shock absorber assembly rear LH.
If it is impossible to tighten the nut at this position,
support the rear axle beam with a jack and load the
rear compartment with a mass of approximately 90
kg (198 lb).
Length of shock absorber:
2WD DRIVE TYPE:
234 mm (9.22 in.)
4WD DRIVE TYPE:
258 mm (10.16 in.)
(b) Fully tighten the nut.
Torque: 115 N*m (1,173 kgf*cm, 85 ft.*lbf)

1. DISPOSE OF SHOCK ABSORBER ASSEMBLY REAR
LH
(a) Fully extend the shock absorber rod.
(b) Using a drill, make a hole in the cylinder as shown in
the illustration to discharge the gas inside the
cylinder.
CAUTION:
• When drilling, since the fragments may fly
out, work carefully.
• The discharged gas is colorless, odorless
and non-poisonous.

(b) Adjust the steering angle.
(1) Draw a line on the RH and LH tie rod and on
the RH and LH rack end, which can easily be
seen.
(2) Using a paper gauge, measure the distance
from the RH and LH tie rod ends to the rack
end screws.
HINT:
• Measure the RH side and LH side.
• Make a note of the measured values.
(3) Remove the RH and LH boot clips from the
rack boots.
(4) Loosen the RH and LH lock nuts.
(5) Turn the RH and LH rack end by the same
amount (but in different directions) according to
the steering angle.
HINT:
1 turn 360 deg. of rack end (1.5 mm (0.059 in.)
horizontal movement) - 12 deg. of steering
angle.
(6) Tighten the RH and LH lock nuts.
Torque: 74 N*m (755 kgf*cm, 55 ft.*lbf)
NOTICE:
Make sure that the difference in length
between RH and LH tie rod ends and rack
end screws are within 1.5 mm (0.059 in.).
(7) Install the RH and LH boot clips.

3. INSPECT FLOW CONTROL VALVE ASSEMBLY
(a) Coat the flow control valve assembly with power
steering fluid and check that it falls smoothly into the
flow control valve due to its own weight.
If the control valve does not fall into the hole
smoothly, replace the vane pump assembly.
(b) Check the flow control valve assembly for leaks.
Close one of the holes and apply compressed air,
392 to 490 kPa (4 to 5 kgf/cm
2, 57 to 71 psi), into
the opposite side hole, and confirm that air does not
come out from the holes in the ends of the flow
control valve assembly.
If air leaks, replace the vane pump assembly.
4. INSPECT FLOW CONTROL VALVE COMPRESSION
SPRING
(a) Using vernier calipers, measure the free length of
the flow control valve compression spring.
Minimum free length:
29.2 mm (1.150 in.)
If the length is less than the minimum, replace the
vane pump assembly.
5. INSPECT PRESSURE PORT UNION
If the union seat in the pressure port union is severely
damaged, replace the vane pump assembly.
6. INSPECT TOTAL PRELOAD
(a) Check that the pump rotates smoothly without
abnormal noise.
(b) Temporarily install the service bolt.
Recommended service bolt:
Thread diameter:
10 mm (0.39 in.)
Thread pitch:
1.25 mm (0.0492 in.)
Bolt length:
50 mm (1.97 in.)
(c) Using a torque wrench, check the pump rotating
torque.
Rotating torque:
0.27 N*m (2.8 kgf*cm, 2.4 in.*lbf) or less
If the rotating torque is not as specified, check the
vane pump housing oil seal.
