Hi everyone,

My Cherokee TD Sport has passed its mot and they said there isnt excessive play, enough to fail, but it could do with adjusting,

A few people have said, is there a wormgear that can be adjusted (Landrover people)

or

Does the box need shimms adding inside??

Anybody know the answer, or is it just a case of waiting till it fails next year and buying a new box?

Best Regards Andy

if you can take it off and get it serviced, that would be your best bet. it might cost ya a few quid but it will save you having to find an other. it is the box and not the steering column isn't it?

[Taranis]

Yes its definitely play in the box, there's not a massive amount, I was just trying to find out if there was any adjustment on the box itself. Landys have a bolt that you basically turn to take a small amount of slack out although you always have to leave a bit of free play so the complicated bits inside the box don't break when offroading.

I have also seen shimms used in boxes before, just wondered what the score was with the Jeep box,

I will try to find a workshop manual somewhere and have a look b4 next mot

Cheers Andy

Yes there is a adjustment procedure, been looking at the fsm,  it says you have to remove the steering box from the jeep to do it properly. You really need the fsm to show you the step by step procedure, you could get one off ebay for a few quid...hope this helps........

CAUTION: Steering gear must be adjusted in the
proper order. If adjustments are not performed in
order, gear damage and improper steering response
may result.
NOTE: Adjusting the steering gear in the vehicle is
not recommended. Remove gear from the vehicle
and drain the fluid. Then mount gear in a vise to
perform adjustments.
WORM THRUST BEARING PRELOAD
(1) Mount the gear carefully into a vise.
CAUTION: Do not overtighten the vise on the gear
case. This may affect the adjustment
(2) Remove adjuster plug locknut (Fig. 23).
(3) Rotate the stub shaft back and forth with a 12
point socket to drain the remaining fluid.
(4) Turn the adjuster in with Spanner Wrench
C-4381. Tighten the plug and thrust bearing in the
housing until firmly bottomed in the housing about
34 N·m (25 ft. lbs.).
(5) Place an index mark on the housing even with
one of the holes in adjuster plug (Fig. 24).
(6) Measure back (counterclockwise) 5.08 mm (0.20
in) and mark housing (Fig. 25).
(7) Rotate adjustment cap back (counterclockwise)
with spanner wrench until hole is aligned with the
second mark (Fig. 26).
(8) Install and tighten locknut to 108 N·m (80 ft.
lbs.). Be sure adjustment cap does not turn while
tightening the locknut.

OVER-CENTER
NOTE: Before performing this procedure, the worm
bearing preload adjustment must be performed.
(1) Rotate the stub shaft with a 12 point socket
from stop to stop and count the number of turns.
(2) Starting at either stop, turn the stub shaft
back 1/2 the total number of turns. This is the center
of the gear travel (Fig. 27).
(3) Place the torque wrench in the vertical position
on the stub shaft. Rotate the wrench 45 degrees each
side of the center and record the highest rotational
torque in this range (Fig. 28). This is the Over-Center
Rotating Torque.
NOTE: The stub shaft must rotate smoothly without
sticking or binding.
(4) Rotate the stud shaft between 90° and 180° to
the left of center and record the left off-center preload.
Repeat this to the right of center and record the
right off-center preload. The average of these two
recorded readings is the Preload Rotating Torque.
(5) The Over-Center Rotating Torque should be
0.40-0.70 N·m (3-7 in. lbs.) higher than the Preload
Rotating Torque.
(6) If an adjustment to the Over-Center Rotating
Torque is necessary, first loosen the adjuster lock
nut. Then turn the pitman shaft adjuster screw back
(COUNTERCLOCKWISE) until fully extended, then
turn back in (CLOCKWISE) one full turn.
(7) Remeasure Over-Center Rotating Torque. If
necessary turn the adjuster screw and repeat measurement until correct Over-Center Rotating Torque
is reached.
NOTE: To increase the Over-Center Rotating Torque
turn the screw CLOCKWISE.
(8) Prevent the adjuster screw from turning while
tightening adjuster lock nut. Tighten the adjuster
lock nut to 49 N·m (36 ft. lbs)

Arn't you going to put the diarams on as well for him?

[Mike Pavelin]

Nah, too technical for me.

[greggmo]

:shock:  

[Dave69]

just sounds difficult so garages can charge more.

if i remember the cherokee power steering fluid is not your normal type so needs to be bought from the dealer. dont get it on your hands as it is carconagenicc

[isle of man]

before you ask it means cancerous.
