ADJUSTMENT POWER STEERING BOX
Service repair no - 57.10.13
WARNING: Adjustments of steering box
should not be required while in warranty
period. If box is stiff or tight and within
warranty, it must be returned to manufacturer. No
attempt must be made to introduce backlash.
1.Apply park brake, select 'P' in automatic
transmission and chock wheels. Support chassis
front on axle stands.
2.Remove engine undertray.
3.Disconnect drag link from steering drop arm.
4.Check torque to turn.
See Fault diagnosis,
Stiff Steering Checklist
5.Centralise steering box.See Centralise
Steering Box
NOTE: Only check for no backlash when
steering box is in central position.
NOTE: If steering wheel is not straight, it
should be repositioned.
See Repair,
Steering Wheel
The adjustment of the steering box ensures
any preload or end float present on centre is
removed.
6.The adjustment is obtained by rocking the drop
arm about centre whilst an assistant slowly
tightens the steering box adjuster screw.
7.Tighten the locknut when all backlash has been
removed.
8.Repeat the check for backlash. If backlash exists
loosen locknut and repeat adjustment
procedure.
9.Turn steering wheel lock to lock and check no
tightness exists.
10.Ensure front wheels are aligned and in straight
ahead position.
See Front Wheel Alignment
11.Adjust drag link 924 mm between ball joint
centres.
12.Connect drag link. Tighten to
40 Nm.
13.Lower vehicle to ground level and remove
chocks.
14.Road test vehicle.
See Fault diagnosis, Road
Test Procedure
NOTE: If steering wheel is not in straight
ahead position when vehicle is travelling
in a straight line, drag link length is
incorrect and is pushing drop arm away from
central position.
Drag link adjust
15.Right hand drive vehicles - if steering wheel is to
right, drag link is too long. If steering wheel is to
left drag link is too short.
Left hand drive vehicles - if steering wheel is to
right, drag link is too short. If steering wheel is to
left drag link is too long.
16.Adjust drag link until steering wheel points
straight ahead when vehicle is travelling in a
straight line.
CENTRALISE STEERING BOX
1.To centralise the box, insert a suitable peg (hole
size 8.06 mm) into the rear of the drop arm and
into the steering box casing to enable rapid and
accurate setting on centre.

not hold vehicle when jacking unless
following procedure is used. If one front wheel
and one rear wheel is raised no vehicle holding or
braking effect is possible. Wheels MUST be
chocked in all circumstances.
Apply parking brake, select 'P' or a gear in main
gearbox and engage low gear in transfer box.
1.Loosen five wheel nuts.
2.Using a suitable trolley jack raise vehicle and
place on axle stands.
See INTRODUCTION,
Information, Jacking
3.Remove wheel nuts and carefully withdraw
wheel over studs.Refit
4.Ensure that retaining studs and nuts are clean.
5.Alloy wheels: Lightly coat wheel mounting spigot
face with a suitable anti-seize compound to
minimise possibility of adhesion between wheel
and spigot face.
6.Refit wheel taking care not to damage stud
threads. (Do not apply oil)
7.Fit wheel nuts and turn by hand for at least three
full threads before using any form of wheel
wrench.
8.Tighten nuts as much as possible using a
suitable wrench.
