Refitting
15Refitting is a reversal of removal, bearing
in mind the following points.
16Where applicable, secure the larger front
guide plate bolt by bending up the lockwasher
tab(s).
17Before tightening the lower
arm-to-crossmember pivot bolts and nuts,
lower the vehicle so that its weight is resting
on the roadwheels, and bounce the vehicle to
settle the suspension. Ensure that the bolts
are orientated as noted during removal.
18On completion, bleed the brakes and
adjust the handbrake.
Models with rear disc brakes
Note: A suitable puller will be required to
remove the drive flange, and a new rear hub
nut must be used on reassembly.
Removal
19With the vehicle resting on its wheels,
loosen the rear hub nut. A suitable extension
bar will be required, as the nut is extremely
tight. Note that the left-hand nut has a
left-hand thread, ie it is undone in a clockwise
direction. Before loosening the nut, ensure
that the handbrake is applied, and chock the
relevant rear wheel.
20Loosen the rear roadwheel nuts on the
side concerned, chock the front wheels, jack
up the rear of the car and support on axle
stands placed under the side members.
21Remove the rear roadwheel.
22Remove the rear section of the exhaust
system - ie from the joint.
23Unscrew the brake pipe from the brake
hose at the bracket on the lower arm (see
illustration). Plug the ends of the pipe and
hose to prevent leakage and dirt ingress, then
detach the hose from the bracket by removing
the U-shaped retaining clip.
24Remove the handbrake cable from the
clip on the lower arm.
25Unbolt the brake caliper and tie it to one
side, taking care not to strain the brake hose.
26Mark the position of the brake disc in
relation to the hub, remove the retaining spire
washer(s), and remove the disc.
27Disconnect the driveshaft from the hub
assembly by unscrewing the six securing
bolts. Support the driveshaft to avoid strainingthe joints, or alternatively, unbolt it from the
final drive unit at the inboard end and remove
the driveshaft from the vehicle. At all times,
avoid bending the driveshaft joints to
excessive angles, and do not allow the shaft
to hang down from one end.
28Unscrew and remove the rear hub nut,
and using a puller pull off the drive flange.
29Unscrew the four bolts securing the hub
carrier and splash shield to the lower arm.
Remove the hub carrier and splash shield.
Note that the stub axle is retained in the hub
carrier.
30Disconnect the ABS sensor, and detach
the lead from the clip on the lower arm.
31Remove the propeller shaft.
32Proceed as shown in paragraphs 7 to 14
inclusive.
Refitting
33Refitting is a reversal of removal, bearing
in mind the following points.
34Where applicable, secure the larger front
guide plate bolt by bending up the lockwasher
tabs.
35When refitting the hub carrier to the lower
arm note that there are two types of bolts used
. The two types of bolt must not be mixed on a
vehicle, but can be changed in complete sets
for the alternative type. A complete set is eight
bolts, four each side. Note that the two types
of bolt have different torque wrench settings.
When renewing the wheel bearings a suitable
puller will be required to remove the drive
flange, and a new rear hub nut must be used
on reassembly.36When refitting the drive flange to the hub
assembly, use a new hub nut, and leave
tightening until the vehicle is resting on its
wheels. Apply the handbrake and chock the
relevant rear wheel when tightening the nut.
37When refitting the brake disc, align the
previously made marks on disc and hub.
38Before tightening the lower
arm-to-crossmember pivot bolts and nuts,
lower the vehicle so that its weight is resting
on the roadwheels, and bounce the vehicle to
settle the suspension. Ensure that the bolts
are orientated as noted during removal.
39On completion, bleed the brakes and
adjust the handbrake.
Saloon and Hatchback models
1With the weight of the vehicle resting on the
roadwheels, work under the vehicle to
unscrew and remove the shock absorber
lower mounting bolt and nut from the relevant
lower arm (see illustration). If desired, the
rear of the vehicle can be raised on ramps to
improve access.
2Working inside the rear of the vehicle,
remove the trim cover behind the side
cushion. The cover is secured by two
self-tapping screws (see illustrations).

the upper mounting bolt and nut. Withdraw
the shock absorber from under the vehicle.
4Refitting is a reversal of removal. Tighten
the mounting bolts securely.
Estate models
Note: On models fitted with heavy duty
Nivomat shock absorbers, follow the
procedure given in Section 13, as the shock
absorber and coil spring are an integrated unit.
5With the weight of the vehicle resting on the
roadwheels, work under the vehicle to unscrew
and remove the two shock absorber lower
mounting bolts from the relevant lower arm(see
illustration).If desired, the rear of the vehicle
can be raised on ramps to improve access.
6Working inside the rear of the vehicle, fold
down the rear seat backrest, fold back the
floor covering and remove the front section of
the luggage compartment floor, which is
secured with 12 self-tapping screws.
7With an assistant supporting the shock
absorber from below, unscrew and remove
the upper mounting nut and washer (see
illustration). Withdraw the shock absorber
from under the vehicle.

9With the weight of the vehicle resting on the
roadwheels, work under the vehicle to
unscrew and remove the shock absorber
lower mounting nut, washer, and rubber
insulator. If desired, the rear of the vehicle can
be raised on ramps to improve access.10Unscrew and remove the top mounting
bolt, nut and washer from the chassis
crossmember. Withdraw the shock absorber
upwards.
