The front suspension is of independent
MacPherson strut type incorporating coil
springs and integral telescopic shock
absorbers. The lower end of each strut is
attached to a hub carrier, which carries the
wheel hub and bearings, and the brake
assembly. The lower end of each hub carrier
is attached to a suspension lower arm by a
sealed balljoint. The inboard ends of the lower
arms are attached to the front suspension
crossmember and the lower arms thus
provide lateral location for the strut
assemblies. The upper end of each strut is
bolted to a suspension turret on the vehicle
body. An anti-roll bar is mounted to the rear of
the lower arms, and resists the roll tendency
of the front suspension.
On Saloon, Hatchback and Estate models,
the rear suspension is also of independent
type, incorporating semi-trailing arms, coil
springs and telescopic shock absorbers. The
semi-trailing arms are attached to the
suspension crossmember at their forward
ends, and to the hub carriers at the rear. Thecoil springs are located between the
semi-trailing arms and the vehicle underbody.
On Saloon and Hatchback models, the shock
absorbers are mounted behind the coil
springs, but on Estate models they are
concentric with the coil springs. On some
Estate models the shock absorbers are of the
self-levelling type. The suspension
crossmember is attached to the vehicle
underbody, and to the final drive unit. Certain
models are fitted with an anti-roll bar which is
mounted to the rear of the final drive unit, and
is attached to the semi-trailing arms by
connecting links.
The rear suspension on P100 models
consists of a beam axle located and
supported by a leaf spring on each side, and
utilizing telescopic shock absorbers to control
vertical movement. The hub and brake
assemblies are attached directly to each side
of the axle. The axle is bolted to the leaf
springs using U-bolts and counterplates, and
the shock absorbers are attached to the
counterplates at their lower ends and the
vehicle underbody at their upper ends.
The steering gear is of the conventional
rack and pinion type located ahead of the
front wheels. Movement of the steering wheelis transmitted to the steering gear by means
of a shaft containing a universal joint. The
front hub carriers are connected to the
steering gear by tie-rods, each having an inner
and outer balljoint. Power-assisted steering is
available on some models, assistance being
provided hydraulically by an engine-driven
pump.
Removal
1Remove the steering gear.
2Support the engine with a jack and
interposed block of wood under the sump.
3Unscrew and remove the engine mounting
nuts from the top of the mountings in the
engine bay (see illustration).
4Raise the engine slightly with the jack, and
ensure that it is safely supported, and just
clear of the engine mounting rubbers.
5Unscrew and remove the nuts, washers and
pivot bolts securing the lower arms to the
crossmember, and pull the arms from the
crossmember. Note that the pivot bolt heads
face to the rear of the vehicle.

6Align the washers, sliders and locking
plates, ensuring that the handle locking plate
is fitted so that the cut-out and Ford logo are
positioned as shown (see illustration).
7Coat the through-bolt threads with a
suitable thread-locking compound, then refit
the through-bolt and the adjuster handle,
ensuring that all components are engaged.
8Position the handle in the locked position,
and secure the through-bolt with a new
locknut and washer.
Removal
1Apply the handbrake, jack up the front of
the vehicle and support on axle stands.
2Working in the engine compartment,
unscrew the bolt securing the intermediate
shaft to the inner column, swivel the clamp
plate to one side, and disconnect the
intermediate shaft.
3Unscrew and remove the clamp bolt
securing the flexible coupling to the steering
gear (see illustration).
4Mark the coupling in relation to the pinion,
then pull off the intermediate shaft and
remove it from the vehicle. The pinion has a
master spline, but making alignment marks
will aid refitting (see illustration).
Refitting
5Refitting is a reversal of removal, but align
the marks on the coupling and pinion, and
tighten all bolts to the specified torque.
Note: A balljoint separator tool will be
required for this operation.
Removal
1Set the front wheels in the straight-ahead
position. Ensure that the steering lock is
engaged and remove the ignition key.
2Apply the handbrake. Loosen the front
roadwheel nuts, jack up the front of the
vehicle and support on axle stands.
3Remove the roadwheels. On P100 models,
mark the position of the roadwheels in relation
to the wheel studs.
4Unscrew and remove the clamp bolts
securing the intermediate shaft flexible
coupling to the steering gear.
5If the original steering gear is to be refitted,
mark the coupling in relation to the pinion. The
pinion has a master spline, but making
alignment marks will aid refitting.
6Slacken the tie-rod end locknuts (see
illustration).
7Remove the split pins and unscrew the
castellated nuts from the tie-rod end-to-hub
carrier balljoints.
8Using a balljoint separator tool, disconnect
the tie-rod ends from the hub carriers.9Unscrew the two steering gear-to-front
suspension crossmember securing bolts, and
withdraw the steering gear from under the
vehicle.
10If required, remove the tie-rod ends.
Refitting
11Refitting is a reversal of removal, bearing
in mind the following points.
12If new steering gear is being fitted, the
central pinion position can be ascertained by
halving the number of turns required to move
the rack from lock to lock.
13Where applicable, align the marks made
on the coupling and pinion.
14When tightening the steering gear-to-front
suspension crossmember bolts, the following
procedure should be used. Tighten the bolts
to the specified “clamping” torque, then
loosen the bolts fully. Re-tighten to the
specified “snug” torque and then further
tighten the bolts through the specified angle.
15Tighten all fixings to the specified torque,
and use new split pins on the balljoint
castellated nuts.
16On P100 models, align the previously
made marks on the roadwheels and wheel
studs.
17On completion, check the front wheel
alignment.
Note: New power steering fluid hose O-rings
will be required when refitting.
Removal
1The procedure is as described for manual
steering gear with the following differences
(see illustration).
2Before removing the steering gear from the
suspension crossmember, place a suitable
container beneath the steering gear. Unscrew
the single bolt securing the power steering
fluid hoses to the pinion housing. Unscrew the
hose unions and drain the power steering
fluid. Plug the ends of the hoses and the
steering gear apertures, or cover them with
masking tape to prevent dirt ingress.

11Place a suitable container under the
pump, unscrew the fluid pipe unions, and
drain the fluid.
12Remove the drivebelt which also drives
the coolant pump and alternator.
13Prevent the pulley from rotating using a
strap wrench (which can be improvised using
an old drivebelt and a large socket and
wrench), and unscrew the three pulley
securing bolts. Withdraw the pulley.
14Unscrew the three pump securing bolts
from the front of the pump bracket, and the
single bolt from the rear of the bracket, and
withdraw the pump (see illustrations).
15Refitting is a reversal of removal, bearing
in mind the following points.
16Reconnect the fluid unions using new O-
rings.
17On completion, bleed the power steering
fluid circuit.
Note: New fluid hose O-rings will be required
when refitting.

1Clean around the hose unions on the
steering gear. Place a suitable container
beneath the steering gear, then remove the
single bolt securing the hoses to the pinion
housing, unscrew the hose unions and drain
the power steering fluid.
2Clean around the hose unions on the pump.
Place a suitable container beneath the pump,
unscrew the hose unions, and drain any
remaining fluid. Ensure that no fluid is allowed
to spill onto the alternator.3If the hoses are to be left disconnected for a
long period of time, plug the ends of the
hoses and the apertures in the steering gear
and pump, or cover them with masking tape
to prevent dirt ingress.
Refitting
4Refit in reverse order using new O-rings.
5On completion top-up the fluid and bleed
the system.
1Unscrew the filler cap from the power
steering pump reservoir and top-up the fluid
level to the maximum mark using the specified
fluid.
2Disconnect the low tension negative lead
from the ignition coil and crank the engine
several times for two second periods while
slowly turning the steering wheel from
lock-to-lock. Top-up the fluid level if
necessary and continue cranking the engine
until the fluid is free of air bubbles.
3Reconnect the coil lead and start the
engine. Check the system for leaks.
4Switch off the engine and refit the filler cap.
5Drive the vehicle for a few miles to warm up
the fluid and expel any remaining air, then
stop the engine and make a final fluid level
check.
