torque wrench, and then through the specified
Stage 2 and Stage 3 angles, using an angle
tightening gauge.
17 Reconnect the ABS wheel speed sensor
wiring connector.
18 Refit the rear brake disc as described in
Chapter 9.
Note: Always renew shock absorbers in pairs
to maintain good road handling.
Removal
1 Chock the front wheels then jack up the
rear of the car and securely support it on axle
stands (see Jacking and vehicle support).
Remove the rear roadwheels.
2 Using a trolley jack, slightly raise the trailing
arm on the relevant side.
3 Unscrew and remove the shock absorber
lower mounting bolt from the trailing arm (see
illustration).
4 Support the shock absorber, then unscrew
and remove the upper mounting bolt and
withdraw the shock absorber from the
underbody bracket (see illustration).
Inspection
5 The shock absorber can be tested by
clamping the lower mounting eye in a vice,
then fully extending and compressing the
shock absorber several times. Any evidence of
jerky movement or lack of resistance indicates
the need for renewal.
6 Examine the mounting rubbers in the shock
absorber for excessive wear.
7 If the shock absorber or its mounting
rubbers are worn excessively, renew the
complete shock absorber.
Refitting
8 Refitting is a reversal of removal, but tighten
the mounting bolts to the specified torque.
Note: Due to the design of the rear
suspension, it is important to note that only
one coil spring should be removed at a time.
Note that the rear springs should be renewed
in pairs.
Removal
1 Chock the front wheels then jack up the
rear of the car and securely support it on axle
stands (see Jacking and vehicle support).
Remove the rear roadwheels.
2 Using a trolley jack, slightly raise the trailing

4 Carefully lower the trailing arm as far as
possible without straining the brake flexible
hoses leading to the rear brakes.
5 Remove the coil spring and spring seats
from the underbody and trailing arm, and
withdraw from under the vehicle. Note that
the upper spring seat incorporates a damper
buffer (see illustrations).
Refitting
6 Refitting is a reversal of removal, but note
the following points.
a) Ensure that the spring locates correctly
on the upper and lower seats, as well as
on the trailing arm and underbody.
b) Tighten the shock absorber lower
mounting bolt to the specified torque.
c) If the springs are being renewed, repeat
the procedure on the remaining side of
the vehicle.
