1989 FORD SIERRA oil

5Refitting is a reversal of removal, with
reference to the note at the beginning of this
Section. Refit any shims in their original noted
positions, and tighten all bolts to the specified
torque.
Removal
1Loosen the rear roadwheel nuts, chock the
front wheels, jack up the rear of the vehicle
and support on axle stands placed under the
side members.
2Prise off the straps which connect the
anti-roll bar to the suspension lower arms
(see illustration).
3Unbolt the two securing brackets from the
underbody, and remove the anti-roll bar (see
illustration).
4The connecting straps can be prised from
the ends of the anti-roll bar, and the
underbody mounting brackets and rubbers,
which are of a split design, can be pulled off.
5When fitting new mounting components,
lubricate the rubber parts with soapy water to
ease assembly.
Refitting
6Refitting is a reversal of removal. Tighten
the anti-roll bar-to-underbody securing bolts
to the specified torque.
Note: All self-locking nuts and spring washers
must be renewed on reassembly.
Removal
1Chock the front wheels, jack up the rear of
the vehicle and support on axle stands placed
under the side members. Note that a loaded
vehicle must not be jacked under the
differential casing.2Support the rear axle with a jack, using an
interposed block of wood to spread the load.
3Remove the propeller shaft.
4Remove the securing circlip and the pivot
pin, and detach the handbrake equaliser from
the linkage on the underbody.
5Remove the handbrake cables from the
clips on the underbody, and from the brackets
on the crossmember. To remove the cables
from the crossmember, remove the U-shaped
retaining clips. Note that the cable adjuster is
secured to the right-hand crossmember
bracket. Ensure that the handbrake is
released before attempting to disconnect any
part of the mechanism.
6Unscrew the brake pipe from the brake
hose on the right-hand side of the chassis
crossmember. Plug the ends of the pipe and
hose to prevent leakage and dirt ingress, then
detach the hose from the crossmember by
removing the U-shaped retaining clip (see
illustration).
7Remove the spring clip and clevis pin and
disconnect the spring from the brake load
apportioning valve lever on the right-hand
side of the underbody (see illustration).
8Detach the exhaust system from the two
rear mountings.
9Unbolt the shock absorbers from the
chassis crossmember.
10Unbolt the leaf springs from the front
brackets on the underbody, (Section 19).
11Lower the rear axle.
12Loosen the spring shackle-to-underbody
bolts, then unbolt the leaf springs from the
spring shackles, and remove the rear
suspension and axle assembly from under thevehicle, guiding the handbrake cables over
the exhaust system.
Refitting
13Refitting is a reversal of removal, bearing
in mind the following points.
14Do not fully tighten the leaf spring
mounting bolts or the spring
shackle-to-underbody bolts until the weight of
the vehicle is resting on the roadwheels.
15Renew all self-locking nuts and spring
washers.
16On completion, check the brake load
apportioning valve adjustment and the
handbrake adjustment. Bleed the rear brake
circuit and check the axle oil level.
Note: All self-locking nuts and spring washers
must be renewed on reassembly.
Removal
1Chock the front wheels, jack up the rear of
the vehicle and support on axle stands placed
under the side members. Note that a loaded
vehicle must not be jacked under the
differential casing.
2Support the relevant side of the rear axle
with a jack, using an interposed block of
wood under the axle tube to spread the load.
3Unscrew the nuts, and remove the two
U-bolts on each side of the vehicle which
secure the axle to the leaf springs (see
illustration). Note that there is no need to

Refitting
3When refitting the fluid hoses, use new
O-rings, and take care not to overtighten the
unions. Note that with the unions fully
tightened it is still possible to rotate and move
the hoses.
4On completion of refitting, bleed the power
steering fluid circuit (Section 34).
Note: New power steering fluid hose O-rings
will be required when refitting.
All engines except 1.8 litre (R6A)
CVH and 2.0 litre DOHC
1Place a suitable container under the power
steering pump, unscrew the fluid hose unions,
and drain the fluid. Ensure that fluid is not
allowed to spill onto the alternator.
2Remove the drivebelts and unbolt the
power steering pump pulley if necessary to
ease removal.
3Unbolt the rear support bar from the pump
and the engine block (see illustration).
4Unbolt the pump from its mounting bracket,
and withdraw the pump from the engine.
5Refitting is a reversal of removal, noting the
following points.
6Tension the drivebelts correctly.
7When refitting the fluid hoses, use new
O-rings, and take care not to overtighten the
unions. 8On completion of refitting, bleed the power
steering fluid circuit.
1.8 litre (R6A) CVH engine
9The removal and refitting procedures are
basically the same as described below for the
2.0 litre DOHC engine, except that the pump
is mounted on a bracket above the alternator
on the front left-hand side of the engine.
2.0 litre DOHC engine
10The pump is mounted on a bracket on the
front right-hand side of the cylinder block.
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.
Removal
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.
1Remove the tie-rod end.
2Unscrew and remove the tie-rod end
locknut from the tie-rod.
3Remove the clips and slide the gaiter from
the tie-rod and steering gear.
4Slide the new gaiter over the tie-rod and
onto the steering gear. Where applicable,
make sure that the gaiter seats in the cut-outs
in the tie-rod and steering gear.
5Secure the gaiter with new clips.
6Refit the tie-rod end locknut to the tie-rod.
7Refit the tie-rod end.
Note: A balljoint separator tool will be
required for this operation.
Removal
1Loosen the relevant front roadwheel nuts,
apply the handbrake, jack up the front of the
vehicle and support on axle stands.
2Remove the roadwheel. On P100 models
mark the position of the roadwheel in relation
to one of the wheel studs before removal.
3Make alignment marks on the tie-rod and
tie-rod end, then loosen the locknut by a
quarter of a turn.
