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)

Check

1. Ensure tyre pressures are correct and vehicle

is at kerbside weight.

2. Roll vehicle backwards and forwards to relieve

stresses in steering and suspension.

3. Ensure road wheels are positioned straight

ahead.

4. Ensure that wheel alignment equipment is

properly calibrated.

5. Following the equipment manufacturer's

instructions, measure the front wheel
alignment. Compare with the figures given in
General Data.

13. Remove bolt from steering box pipe retaining

clip. Leaving the PAS reservoir oil pipe in place,
release pipe retaining clip and PAS cooler pipe
from steering box, discard the seal.

14. Fit tool LRT-57-041 to steering box housing.
15. Fit seal to PAS oil cooler pipe.
16. Fit PAS cooler pipe to LRT-57-041 align the

retaining clip to pipes and tighten bolt to 24 Nm
(18 lbf.ft).

17. Connect test hoses LRT-57-002 to LRT-57-

041 and tighten unions. Ensure all pipes and
fittings are clear of engine rotating parts.

18. Hang pressure gauge in a safe position under

bonnet.

19. LHD only: Fit turbocharger intercooler feed

pipe and vacuum connection and fit PAS
reservoir to mounting bracket. Fit air intake
hose to turbocharger and air cleaner and
connect multiplug to MAF sensor. The above
parts must be refitted in order to run the
engine.

20. Fill PAS reservoir, connect battery earth lead.

Start engine and allow air to bleed from PAS
system, by turning steering from lock to lock.
Stop engine and check PAS fluid level.

21. Ensure steering system is free from leaks and

maintain maximum fluid level during test.

22. Open the test valve on LRT-57-001 and start

the engine.

23. With the engine at idle and normal running

temperature, slowly turn the steering wheel and
hold on lock.

24. Note reading on pressure gauge.
25. Repeat pressure check on opposite lock, again

noting the reading on the pressure gauge.

26. The test pressure should be between 21 and 62

bar, (300 to 900 lbf/in

2

. Pressure will rise to 62

bar (900 lbf/in

2

) when held on full lock.

27. With the engine at idle, centralise the steering

wheel. Pressure should read 7 bar (100 lbf/in

2

)

or below.

28. Pressure outside the above tolerance indicates

a fault.

29. To determine if fault is in steering pump or

steering rack, close the valve on LRT-57-001
for a maximum of five seconds. Pump damage
may occur if test valve is closed for longer
periods.

30. If the gauge does not register between 75 and

103 bar, (1500 lbf/in

2

) (maximum pump

pressure), the pump is faulty.

31. If maximum pump pressure is obtained,

suspect the steering box.

32. On completion, stop engine, disconnect battery

earth lead and syphon fluid from PAS reservoir.

33. LHD only: Disconnect multiplug from MAF

sensor, remove air intake hose clips and move
hose aside.

34. LHD only: Release PAS reservoir from

mounting, for access to turbocharger
intercooler pipe.Remove vacuum hose from
turbocharger intercooler pipe.Release clips and
disconnect intercooler pipe from turbocharger.

35. Remove test equipment from tool LRT-57-041.
36. Remove bolt and clip from steering box.
37. Release PAS cooler pipe from tool LRT-57-041

and discard seal. leaving PAS reservoir oil pipe
in place, release tool LRT-57-041 from
steering box and discard seal.
