Check

1. Raise front of vehicle.

WARNING: Do not work on or under a
vehicle supported only by a jack. Always
support the vehicle on safety stands.

2. Remove nut securing drag link to drop arm.
3. Using LRT-57-036, break taper joint and

release drag link.

4. Ensure steering is centralised.
5. With the drop arm held, check for rotational

movement at the intermediate shaft universal
joint. If any movement exists, the steering box
requires adjusting.

Adjust

1. Loosen lock nut on steering box adjuster and

tighten adjuster until movement is removed at
universal joint.

CAUTION: Ensure that steering box is
centralised before adjustment. Never over
adjust, free play should just be eliminated.

2. When adjustment is correct, hold the adjuster

and tighten adjuster locknut.

3. Turn steering wheel from lock to lock and check

no tightness exists.

LUBRICANTS, Fluids.

CAUTION: Ensure no dirt is allowed to enter
the steering reservoir when the cap is
removed.

3. Start engine and run to normal operating

temperature.

4. Position container to catch fluid spillage from

steering box.

5. With engine at idle speed, and an assistant

turning the steering from lock to lock, loosen
bleed screw on top of steering box. Keep PAS
fluid reservoir topped up and allow all air to
bleed from system. When fluid from bleed
screw is free of air, tighten bleed screw.

CAUTION: Do not hold steering at full lock
for longer than 10 seconds.

6. Stop engine.
7. Clean spilled PAS fluid from steering box and

surrounding area.

CAUTION: Power steering fluid will damage
paint finished surfaces. If spilled,
immediately remove fluid and clean area
with water.

8. Check fluid level in PAS fluid reservoir and fill to

upper level mark. If fluid is aerated, wait until
fluid is free from bubbles.

9. Fit PAS fluid reservoir filler cap.

Steering linkage - centralise

$% 57.35.05

The following procedure assumes that the front
wheel alignment is correctly adjusted.

Adjust

1. Raise front of vehicle, and position the road

wheels at straight ahead.

WARNING: Do not work on or under a
vehicle supported only by a jack. Always
support the vehicle on safety stands.

2. Remove nut securing drag link to drop arm.

Using tool LRT-57-036 break taper joint and
release drag link from drop arm.

3. Fit centralising bolt to steering box and ensure

that front road wheels are in the straight ahead
position.

4. Loosen clamp bolts on drag link.

5. Adjust drag link so that taper joint is centralised

in drop arm, then tighten drag link clamp bolts:
Tighten M8 bolts to 22 Nm (16 lbf.ft) and M10
bolts to 33 Nm (24 lbf.ft).

6. Connect drag link to drop arm and tighten nut to

80 Nm (59 lbf.ft).

7. Remove steering box centralising bolt.
8. Remove stand(s) and lower vehicle.
9. Road test the vehicle and check that the

steering wheel is centralised. If steering wheel
is not centralised, proceed as follows.

10. Slacken drag link adjuster clamp bolts.
11. Without disconnecting drag link from drop arm,

adjust the length of the drag link to bring the
steering wheel to the central position.

CAUTION: Repositioning the steering wheel
on its splines cannot correct small (less
than 5

°

) errors in steering wheel alignment.

Always rectify small errors in alignment by
adjusting the drag link as detailed above,
ensuring that steering box centralisation is
maintained.

12. Tighten drag link clamp bolts: Tighten M8 bolts

to 22 Nm (16 lbf.ft) and M10 bolts to 33 Nm (24
lbf.ft)
