158 Front Suspension


Installed view of the front suspension. When using a floor jack locate the head of the jack on the crossmember.
(2) Remove the cap, split pin, castellated re-
tainer and with the aid of an assistant applying the
brakes, loosen and remove the hub nut.
(3) Remove the split pin and the castellated nut
retaining the tie rod end to the steering knuckle. (4) Disconnect the tie rod end from the steering
knuckle using a suitable puller. Alternatively place a
suitable dolly or hammer against one side of the
steering knuckle eye and strike the opposite side with
a hammer.
(5) Remove the brake caliper anchor plate bolts,
withdraw the caliper from the disc and support it with
a piece of wire inside the inner mudguard. Ensure that
the brake hose is not twisted.
(6) Withdraw the brake disc from the hub.
(7) Loosely install the hub nut and tap on the nut
with a soft faced hammer to separate the drive shaft
from the hub. (8) Place a mark on the suspension unit to
steering knuckle cam head bolt to ensure correct wheel
alignment on assembly. (9) Remove the steering knuckle to suspension
unit nuts and bolts. (10) Remove the split pin and the castellated nut
retaining the lower ball joint stud to the steering
knuckle. (11) Disconnect the ball joint stud from the steering knuckle using a suitable puller or alternatively
place a suitable dolly or hammer against one side of
the steering knuckle eye and strike the opposite side
with a hammer.

(12)
Withdraw the steering knuckle from the
vehicle taking care not to drop the drive shaft or
damage its boot. (13) Clean and check the steering knuckle for
wear, cracks and damage. (14) If necessary, dismantle the hub and check
the bearing assembly using the dismantling procedure
described later in this section. Installation is a reversal of the removal procedure
with attention to the following points:

(1) Install the steering knuckle and hub assembly
over the drive shaft and loosely install the ball joint
stud nut and the suspension unit to knuckle bolts and
nuts.
(2) Ensure that the suspension unit to steering
knuckle cam head bolt mark s are aligned and tighten
the retaining nuts to the specified torque.
NOTE: If the cam head bolt is not installed
in its original position, a wheel alignment
should be performed.

(3) Tighten the ball joint to steering knuckle stud
bolt to the specified torque.

the ball joint or bushes as described later in this
section.

Installation is a reversal of the removal procedure
with attention to the following points:

(1) When installing the control arm bush
bracket, ensure that the protrusion on the bracket is
towards the inside of the vehicle.
(2) Do not fully tighten the control arm bush
bolts and through bolt nut until the curb weight of the
vehicle is on the suspension.
NOTE: Curb weight is with the vehicle
unladen except for a full tank of fuel and
normal amounts of oil and water and with
the spare lyre, jack and hand tools in their
normal positions.

(3) Tighten the ball joint nut to the specified
torque and retain with a new split pin.

TO CHECK AND RENEW BALL JOINT
(1) Remove the control arm from the vehicle as
previously described.

(2) Install the ball joint nut and turn the ball
joint at least ten revolutions to ensure that the ball
joint is correctly seated. (3) Using a spring scale with the hook placed
over the split pin hole, check the ball joint swinging
torque. A new ball joint should measure 15.7-80.4 N
and a used ball joint should measure 7.8-80.4 N.
Renew the ball joint if necessary. (4) Using a small torque wrench or preload
gauge, measure the force requi red to rotate the ball
joint. A new ball joint should measure between
1.0-4.9 Nm and a used ball joint should measure
between 0.5-4.9 Nm. Renew the ball joint if neces-
sary.

(5) To renew the ball joint, remove the snap ring
from the stud end of the ball joint using snap ring
pliers. (6) Support the control arm in a press, ball joint
stud uppermost, with a suitable tube that is large
enough for the ball joint to pass through. (7) Press the ball joint out from the control arm.
(8) Press a new ball joint into the control arm
using a suitable tube that pushes on the outer circum-
ference of the joint only.
(9) Install the snap ring and install the
control
arm to the vehicle as previously described.

TO RENEW CONTROL ARM BUSHES
(1) Remove the control arm from the vehicle as
previously described. Mark the position of the rear
control arm bush. (2) To remove the rear control arm bush use a
bearing puller and a press. When installing the bush
use a suitable tube that pushes on the inner edge of the
bush only. NOTE: Ensure that the bush is installed
with the flat portion in its original location.

(3)
To remove the front control arm bush use a
suitable tube that pushes on the outer circumference
of the bush and a split tu be supporting the control
arm. (4) After the bush has been pressed out approx-
imately half way, cut the protruding part of the bush
using a hacksaw. Cutting the bush in this way will
allow removal.
(5) Support the control arm and push the new
bush in from the outside using a suitable tube that
pushes on the outer circumference only. (6) Install the control ar m to the vehicle as
previously described.
6. STABILISER BAR
TO REMOVE AND INSTAL
(1) Raise the front of the vehicle and support it
on chassis stands.

(2) Remove the bolts at the flexible joint retain-
ing the front engine pipe to the exhaust pipe located
below the stabilizer bar. (3) Remove the bolt from the exhaust pipe
mounting below the stabilizer bar. Disconnect the
exhaust pipe at the flexible joint and allow the front of
the pipe to hang down. (4) Remove the stabilizer bar bracket retaining
bolts and remove the stabilizer bar brackets from the
vehicle. (5) Remove the stabilizer bar lower link nuts
from each control arm. When removing the lower nuts
it may be necessary to hold the upper nuts with a
spanner.
(6) Maneuver the stabilizer bar from the
vehicle.
Installation is a reversal of the removal procedure
with attention to the following points:

(1) Ensure that the stabilizer bar mounting rub-
bers are in a serviceable condition and secure in the
mounting brackets.
