Models before August 1989
1Remove the stub axle carrier as described
in the previous Section.
2Screw the wheel nuts onto the studs to
protect the threads. Clamp the stub axle
carrier in a vice by means of the studs and
nuts; do not overtighten.
3Remove the dust cap from the hub nut,
carefully levering it free (see illustration). A
new cap and a new hub nut will be required for
reassembly.
4Undo the hub nut. This nut is very tight. The
right-hand hub nut has a left-handthread,
therefore it is undone in a clockwisedirection.
5Remove the ABS rotor from below the hub
nut.
6Lift the carrier off the stub axle, tapping it
with a mallet if necessary to free it. Remove
the bearing inner race from the carrier.
7Prise the oil seal out of the carrier and
recover the bearing outer race.8Drive the bearing tracks out of the stub axle
carrier using a blunt drift and a hammer. Be
careful not to mark the bearing seats.
9Clean all old grease and debris from the
stub axle carrier.
10New bearing components are matched in
production and must only be fitted as a set.
Only the manufacturer’s approved
components should be used in order to obtain
the required long service life and freedom from
adjustment.
11Drive the new bearing tracks into the
carrier, preferably using a suitable diameter
tube to seat them. Make sure the tracks are
fully seated.
12Work some clean grease into the bearing
races. Use high melting-point lithium-based
grease (to Ford spec. SAMIC-9111A or
equivalent). Make sure all the spaces between
the rollers are filled; do not pack grease into
the space between the inner and outer
bearings however.
13Fit the bearing outer race. Grease the lips
of a new oil seal and fit it to the stub axle
carrier, lips facing inwards. Seat the seal with
a pipe or large socket and a mallet.
14Offer the carrier to the stub axle, tapping it
home if necessary. Fit the bearing inner race
over the stub axle.
15Refit the ABS rotor, dished face
uppermost.
16Fit a new hub nut (left-hand thread on the
right-hand hub) and tighten it to the specified
torque.17Fit a new dust cap and seat it by tapping
round the rim (see illustration).
18Refit the stub axle carrier.
Models from August 1989
19Modified front wheel bearing assemblies
were fitted to all models after 1989. The
modified bearings are of similar design, but
are interference fit type bearings. This was to
reduce the amount of endfloat present at the
wheel hub and to improve bearing preload
tolerances. This was achieved by increasing
the diameter of the stub axle, thus causing the
axle to be an interference fit in the bearing.
Note that the modified bearings can be fitted
to earlier models which were originally
equipped with non-interference fit front wheel
bearings. Note: Due to the design of the
interference fit bearings, a suitable heavy duty
bearing puller and a hydraulic press and
several suitable mandrels will be required to
remove the originalbearing and install the new
one.
20Interference fit front wheel bearings can be
removed and refitted as described above,
noting the following points.
a)It will be necessary to press or draw the
stub axle out of the carrier using a
hydraulic press or a suitable bearing
puller.
b)Draw the outer bearing off the stub axle
using a suitable bearing puller.
c)Press new bearing tracks into the hub
carrier using a suitable tubular spacer
which bears only on the tracks outer edge.
d)Pack the new outer bearing with Ford
grease (SAM-1C9111-A) and press the
bearing into the carrier.
e)Press a new seal into position in the
carrier and pack all cavities with the
specified grease.
f)Position the hub carrier over the stub axle
and press the carrier onto the axle using a
suitable tubular spacer which bears only
on the bearing track outer edge.
g)Pack the new inner bearing with the
specified grease then press the bearing
onto the stub axle, using a suitable tubular
spacer, whilst rotating the hub carrier to
ensure that the bearing is correctly seated.
h)Whilst tightening the hub nut to the
specified torque, rotate the hub carrier to
ensure that the bearing preload is correct
and bearings are correctly seated. Once
the nut is tightened to the specified
torque, rotate the hub carrier 20 times to
settle the bearings in position then
recheck that the hub nut is tightened to
the specified torque. Pack the inner
bearing with the specified grease and fit a
new dust cap.

8The anti-roll bar bushes (compliance
bushes) can be removed by cutting off their
flanges with a chisel, then pressing or tapping
out the remains. Fit new bushes by tapping
them home with a tube or socket.
9The pivot bush can be pressed out using a
bench vice and a couple of large sockets or
suitable pieces of tube. The new pivot bush
should be lubricated with soap or glycerine
(notoil or grease) before being fitted in a
similar fashion. Do not keep the new bush
compressed in the tube for longer than
necessary, in case it becomes permanently
distorted.
10Commence refitting by offering the arm to
the anti-roll bar. Make sure that the shallow
dished washer and the plastic cover are fitted
on the inboard side of the bar (furthest from
the nut).

but do not finally tighten any fastenings until
the weight of the vehicle is back on the
wheels. Tighten in the following order:
a)Anti-roll bar clamps
b)Anti-roll bar-to lower arm nuts
c)Lower arm pivot nut and bolt
8Make sure that the anti-roll bar clamp
bushes are not twisted on completion.
Compliance bushes
1These are described in Section 18. It is not
strictly necessary to remove the lower arms to
renew these bushes, though obviously access
is not good with the arms installed.
Clamp bushes
2Although it is possible to remove and refit
the clamp bushes without removing the anti-
roll bar, since the bushes are split, this is not
recommended by the makers.
3Remove the anti-roll bar as described in the
previous Section.4Slide the clamp bushes off the anti-roll bar,
if necessary prising them open a little first.
5Lubricate the new bushes with glycerine or
soap and slide them into position with the split

8Examine all components for wear and
damage and renew as necessary. The shock
absorber must be renewed if it is leaking, or if
it shows uneven resistance when “worked”
with its lower end clamped in a vice. In theory
springs and shock absorbers should be
renewed in pairs in order to maintain balanced
handling characteristics.
9Commence reassembly by sliding the bump
stop onto the shock absorber piston rod. Refit
the gaiter.
10Make sure that the spring seats are clean,
then fit the compressed spring to the lower

6Refit by reversing the removal operations.
Tighten the shock absorber mountings to the
specified torque. On models with ride height
control, use new O-rings on the air line union.
The ride height control system is an optional
extra, designed to keep the rear suspension
height constant regardless of vehicle load.
This is obviously useful if heavy loads are often
carried, or if the vehicle is used for towing.
The main components of the system are a
height sensor, a compressor and two special
rear shock absorbers. The compressor
supplies air to the shock absorbers, so
“pumping up” the rear suspension, when so
commanded by the height sensor. Other
components include the connecting pipes,
electrical wiring and a compressor relay. The
relay is mounted behind the glovebox.
Variations in vehicle height are not
recognised by the system for approximately
20 seconds, in order to prevent responses to
temporary changes such as those induced by

The components of the alarm system are a
control module, tripping switches, activating
switches, an alarm horn and a signal buzzer.
The control module is located behind the
facia. It determines whether the alarm is set or
not, monitors the tripping switches and the
ignition circuit, and limits the duration of the
alarm to 30 seconds. This last item is a legal
requirement. The control module also
operates the signal buzzer to tell the driver
that the alarm is set, and controls the activator
delay.
The tripping switches on the doors and
tailgate are the same as those used for “open
door” warnings in the AWS. The bonnet switch
is peculiar to the alarm system.
The activating switches are fitted to the
front door lock barrels, where they are
activated by a lug on the end of the barrel.
They only make contact momentarily as the
lock is operated.
The alarm horn is mounted next to the
battery. Both the horn and its leads are
claimed to be inaccessible without opening
the bonnet. The signal buzzer is also mounted
under the bonnet.
No service, repair or component renewal
procedures have been published for the alarmsystem components on earlier models. Any
problems arising which cannot be dealt with
by component substitution should therefore
be referred to a Ford dealer.
