7Working in the engine compartment,
unscrew the strut upper mounting nut, at the
same time supporting the strut from below.
Use a 6 mm Allen key inserted in the end of
the strut piston rod to prevent the rod from
turning as the upper mounting nut is
unscrewed (see illustration). On some
models, the upper mounting nut may be fitted
with a plastic cover. Note the upper mounting
cup under the nut.
8Withdraw the strut from under the wing of
the vehicle.
Overhaul
9To dismantle the strut, proceed as follows.
10Using spring compressors, compress the
coil spring. Do not attempt to compress the
spring without using purpose-made spring
compressors, as the spring is under
considerable tension, and personal injury may
occur if it is suddenly released (see
illustration).
11Hold the piston rod as described in
paragraph 7, unscrew the nut from the pistonrod and remove the lower cup, bearing, spring
seat, gaiter, coil spring and bump stop (see
illustration).
12Working in the engine compartment,
remove the upper cup and nylon spacer, and
if required prise out the rubber insulator.
13Clean all the components and examine
them for wear and damage. Check the action
of the shock absorber by mounting it vertically
in a vice and operating the piston rod several
times through its full stroke. If any uneven
resistance is evident, the shock absorber
must be renewed. Renew any worn or
damaged components as applicable.
Refitting
14Reassembly and refitting is a reversal of
dismantling and removal, bearing in mind the
following points.
15When reassembling, ensure that the gaiter
is fitted over the bump stop, and that the ends
of the coil spring are correctly located on the
spring seats. Also ensure that the bearing is
correctly located on the upper spring seat.
16Fit the nylon spacer over the piston rod
before fitting the strut to the top mounting.
17Tighten all fixings to the specified torque.
18On P100 models align the previously
made marks on the roadwheel and wheel
stud.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 (see
“Jacking and Vehicle Support”).
2Remove the roadwheel. On P100 models
mark the position of the roadwheel in relation
to one of the wheel studs before removal.
3Remove the front brake caliper but do not
disconnect the hydraulic hose. Support the
caliper on an axle stand, or suspend it with wire
from the coil spring to avoid straining the hose.
4Mark the position of the brake disc in
relation to the drive flange, and on Saloon,
Hatchback and Estate models, remove the
retaining screw or spire washer(s), as
applicable, and remove the disc. On P100
models, unscrew the five retaining nuts and
remove the wheel adapter plate and disc.
5Where applicable, unbolt the ABS wheel
sensor from the hub carrier and unplug the
wiring connector. Place the sensor to one side.
6Remove the split pin and unscrew the
castellated nut securing the tie-rod end to the
hub carrier. Using a balljoint separator tool,
disconnect the tie-rod end from the hub carrier.
7Repeat the procedure given in the previous
paragraph for the lower arm-to-hub carrier
balljoint.
8Unscrew and remove the pinch-bolt which
secures the hub carrier to the strut (see
illustration). Using a suitable lever, such as a
cold chisel, lever the hub carrier clamp legs
and wedge them apart. Withdraw the hub
carrier from the strut.
Refitting
9Refitting is a reversal of removal, but use
new split pins on the castellated nuts, and
align the previously made marks on the brake
disc and hub. Tighten all fixings to the
specified torque.
10On P100 models align the previously
made marks on the roadwheel and wheel
stud.
