1985 FORD GRANADA clock

5Extract the piston seal from the groove in
the bore, using a blunt instrument (see
illustration). Discard the seal and dust boot.
6Clean the piston and bore with methylated
spirit and inspect them for scuffs, scores or
other damage. If the piston is corroded it must
be renewed. Slight imperfections in the bore
can be polished out with wire wool.
7Place the clean component on a clean
surface ready for reassembly. Lubricate the
caliper hose with clean hydraulic fluid.
8Fit the new piston seal to the groove in the
bore, using fingers only to work it into position.
9Lubricate the piston with clean hydraulic
fluid and fit the dust boot over the piston,
making sure it is the right way up. Insert the
piston into the bore and press it home,
engaging the dust boot lip with the groove on
the caliper (see illustration).
10This completes the overhaul of the hydraulic
components. Items such as slide bolts and
bracket can also be renewed if necessary.
11Remove the bleed screw while the caliper
is on the bench and apply a little anti-seize
compound to its threads, to avoid trouble in
undoing it later.
1With the ignition off, pump the brake pedal
at least 20 times (or until it becomes hard) to
depressurise the system.
2Chock the front wheels and release the
handbrake. Slacken the rear wheel nuts, raiseand support the vehicle and remove the
relevant wheel.
3Disconnect the pad wear warning wires,
when fitted.
4Disconnect the flexible hose from the brake
pipe. Plug or cap the open unions to reduce
spillage and to keep dirt out. Unscrew the
flexible hose from the caliper and remove it.
5Remove the two slide bolts. Lift the caliper
off the pads and bracket, at the same time
unhooking the handbrake cable (see
illustrations). Alternatively, the two bracket-
to-hub bolts can be removed and the caliper
and bracket separated on the bench.
6Refit by reversing the removal operations,
but before refitting the wheel, bleed both rear
calipers as described in Section 2.
7When bleeding is complete, pump the brake
pedal several times to bring the pads up to the
disc, then check the operation of the
handbrake.
Note: Complete dismantling of the rear caliper
should not be attempted unless Ford spring
compressor (tool No 12-007) is available. or
unless the problems likely to arise in the absence
of the tool are understood. Renewal of the piston
seal and dust boot requires no special tools.
1Clean the caliper externally and mount it in a
soft-jawed vice.
2Rotate the piston anti-clockwise until it isprotruding from the bore by about 20 mm (0.8 in).
Free the dust boot from the groove in the
piston, then carry on unscrewing the piston
and remove it. Remove and discard the dust
boot.
3The piston and bore may now be cleaned
and examined, and the piston seal and dust
boot renewed, as described for the front
caliper (Section 10).
4The piston adjuster nut seal should also be
renewed. Remove the circlip from the piston,
then extract the thrustwashers, wave washer
and thrust bearing. Note the fitted sequence of
these components. Finally remove the nut
(see illustrations).
5Remove the seal from the nut, noting which
way round it is fitted. Clean the nut with
methylated spirit. Lubricate the new seal with
clean hydraulic fluid and fit it to the nut.

reference to horn switch plate retaining
screws. Note that the wheel is retained by a
bolt, not a nut as on earlier models. To gain
access to the bolt, prise out the horn button
and disconnect the wiring connectors.
1This operation is for correcting small errors
in steering wheel centralisation - up to 60°. For
larger errors, remove the steering wheel and
make a rough correction by repositioning the
wheel on refitting.
2Drive the vehicle in a straight line on a level
surface. Note the angle by which the steering
wheel deviates from the desired straight-
ahead position.
3Raise the front of the vehicle by driving it
onto ramps, or with a jack and axle stands
(see “Jacking”).
4Slacken both track rod end locknuts. Also
slacken the steering rack bellows outer clips.
5Make alignment marks between each track
rod end and its rod, so that the amount of
rotation applied can be accurately determined.
6Turn both track rodsin the same direction
to correct the steering wheel position. As a
rough guide, 19°of track rod rotation will
change the steering wheel position by 1°. To
correct error at the steering wheel, rotate both
track rods anti-clockwise (viewed from the
left-hand side of the vehicle), and the reverse
to correct as anti-clockwise errors. Both track
rods must be rotated by the same amount.
7Tighten the bellows clips and the track rod
end locknuts when adjustment is correct.
Lower the vehicle.
1Disconnect the battery negative lead.
2Position the steering in the straight-ahead
position.
3Remove the steering wheel. This is not
essential, but will improve access.
4Working under the bonnet, disconnect the
intermediate shaft universal joint from the
steering column shaft.5Remove the steering column shrouds and
disconnect the switch multi-plugs. Do not
forget the ignition/starter switch.
6Disconnect the bonnet release cable from the
operating lever on the underside of the column.
7Prise out the driver’s side air vent. Remove
the under-dash insulation and trim panel on
the driver’s side, unclipping the bulb failure
module, where applicable.
8Remove the three nuts which secure the
column height adjuster to the mounting bracket
(see illustration). Remove the column assembly
by drawing it into the vehicle. Do not drop it or
otherwise mistreat it if it is to be re-used.9When refitting, have an assistant guide the
column shaft into the intermediate shaft
universal joint. Secure the column with the
three nuts inside the vehicle and adjust it to
the minimum length position, then tighten the
coupling pinch-bolt.
10Complete refitting by reversing the
removal operations.
1Remove the steering column (see
illustration).
2Insert the key into the lock and turn it to
position 1. (If the lock has failed so that the key
will not enter, destructive methods will have to
be used.)

times, then use a proprietary balljoint
separator to break the taper (see illustration).
5Use a stout piece of wood to lever the lower
arm downwards and free the balljoint from the
stub axle carrier.
6Remove the ABS wheel sensor from its
hole.
7Remove the spring clip from one of the
wheel studs and pull the brake disc off the
hub.
8Remove the stub axle carrier pinch-bolt.
Spread the stub axle carrier by carefully
introducing a chisel or blunt instrument into its
slot. Draw the stub axle carrier off the
suspension strut and remove it.
9Refit by reversing the removal operations,
noting the following points:
a)Tighten all fastenings to the specified
torque
b)Use new split pins, when applicable
c)Renew the wheel sensor O-ring if
necessary; clean the sensor and its bore,
and smear them with wheel bearing
grease
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.

15Bleed the brake hydraulic system and
adjust the handbrake on completion.
Models from 1987
16From 1987, the tab washer which secures
the guide plate centre bolt on each side has
been deleted. A self-locking bolt and plain
washer are used instead.
17The new bolt and washer should be fitted
to earlier models if the old bolt has been
removed for any reason. The tab washer
should be discarded.
18The tightening torque for the new bolt
remains the same as that given for the original.
1Remove the wheel trim. Apply the
handbrake and chock the front wheels.
2Slacken the driveshaft stub axle. This nut is
very tight. The left-hand nut has aleft-hand
thread, therefore it is undone clockwise.
3Remove the brake disc.
4Remove the driveshaft stub axle.
5Remove the four bolts which secure the
hub. Pull the hub off the driveshaft stub,
leaving the disc splash shield loose.
6Refit by reversing the removal operations.

squarely with the help of a piece of pipe or
tube.
6Thoroughly grease the bearing races and
pack the lips of the oil seals with grease.
7Fit the races and the oil seals, lips inwards.
Seat the oil seals with a mallet and the pipe or
tube.
8Refit the rear hub.
1This procedure is only specified by the
manufacturers as applying to the rear wheels,
but there is no reason to believe that it will not
work on the front.
2Remove the rear wheel, brake caliper and
brake disc.
3Drive the wheel stud out of the hub flange. 4Insert the new stud from the inboard side of
the flange. Engage the splines by hand
pressure, then draw the stud into place with a
wheel nut and progressively thicker spacers
(see illustration).

the circuit between the relevant connector and
the battery is problem-free.
13Continue to check the remainder of the
circuit in the same fashion.
14When a point is reached at which no
voltage is present, the problem must lie
between that point and the previous test point
with voltage. Most problems can be traced to
a broken, corroded or loose connection.
Finding a short-circuit
15To check for a short-circuit, first disconnect
the load(s) from the circuit (loads are the
components which draw current from a circuit,
such as bulbs, motors, heating elements, etc).
16Remove the relevant fuse from the circuit,
and connect a circuit tester or voltmeter to the
fuse connections.
17Switch on the circuit, bearing in mind that
some circuits are live only when the ignition
switch is moved to a particular position.
18If voltage is present (indicated either by
the tester bulb lighting or a voltmeter reading),
this means that there is a short-circuit.
19If no voltage is present, but the fuse still
blows with the load(s) connected, this
indicates an internal fault in the load(s).
Finding an earth fault
20The battery negative terminal is connected
to “earth” - the metal of the engine/transmission
and the car body - and most systems are wired
so that they only receive a positive feed, the
current returning via the metal of the car body.
This means that the component mounting andthe body form part of that circuit. Loose or
corroded mountings can therefore cause a range
of electrical faults, ranging from total failure of a
circuit, to a puzzling partial fault. In particular,
lights may shine dimly (especially when another
circuit sharing the same earth is in operation),
motors (eg wiper motors or the radiator cooling
fan motor) may run slowly, and the operation of
one circuit may have an apparently-unrelated
effect on another. Note that on many vehicles,
earth straps are used between certain
components, such as the engine/transmission
and the body, usually where there is no metal-to-
metal contact between components, due to
flexible rubber mountings, etc.
21To check whether a component is properly
earthed, disconnect the battery, and connect
one lead of an ohmmeter to a known good
earth point. Connect the other lead to the wire
or earth connection being tested. The
resistance reading should be zero; if not,
check the connection as follows.
22If an earth connection is thought to be
faulty, dismantle the connection, and clean
back to bare metal both the bodyshell and the
wire terminal, or the component’s earth
connection mating surface. Be careful to
remove all traces of dirt and corrosion, then
use a knife to trim away any paint, so that a
clean metal-to-metal joint is made. On
reassembly, tighten the joint fasteners
securely; if a wire terminal is being refitted, use
serrated washers between the terminal and
the bodyshell, to ensure a clean and secure
connection. When the connection is remade,
prevent the onset of corrosion in the future byapplying a coat of petroleum jelly or silicone-
based grease, or by spraying on (at regular
intervals) a proprietary ignition sealer, or a
water-dispersant lubricant.
Headlight
1Open and prop the bonnet. Remove the
cover from the rear of the headlight unit by
twisting it anti-clockwise.
2Disconnect the wiring plug from the
headlight bulb. Release the spring clip by
squeezing its legs together and move it clear
of the bulb (see illustration).
3Remove the headlight bulb (see
illustration). Caution: If the lights have just
been in use, the bulb may be extremely hot.
4When handling the new bulb, use a tissue or
clean cloth to avoid touching the glass with
the fingers. If the glass is accidentally touched,
wipe it clean using methylated spirit. Moisture
and grease from the skin can cause
blackening and rapid failure of the new bulb.
5Fit the new bulb, making sure that the legs
and cut-outs in the bulb base and the reflector
match up. Secure with the spring clip.
6Reconnect the wiring plug. Check the
headlight for correct operation, then refit and
secure the rear cover.
Front parking light (sidelight)
7Gain access as for the headlight bulb, then
pull the parking light bulbholder from the
headlight reflector.
8Extract the wedge base bulb from the
holder (see illustration). Fit the new bulb, refit
the bulbholder and check for correct
operation.
Auxiliary driving light (when fitted)
9From above the auxiliary light unit, release
the cover spring clip and remove the cover
(see illustration).
10Release the spring clip from the bulb.
Withdraw the bulb and unplug its wiring
connector (see illustration). Caution: If the
lights have just been in use, the bulb may be
extremely hot.
11Do not touch the glass of the new bulb
with the fingers.
