rossbeam
A
fully stressed, pressed steel and tube fa
brication with integral lower wishbone tie bars, the crossbeam is secured to the
body on four resilient mountings.
The crossbeam incorporates mounting points for:
The u
pper and lower wish
bone fulcrum bolts.
The
stabilizer bar
The power steering rack. The engine h

ydramounts.
R

Upper
Wishbones
Each
upper wi
shbone assembly is a on
e-piece steel forging incorporating:
A pres
s-fit ball joint.
Press-fi

t bushes for location of the upper fulcrum bolt.
Lower Wishbones
Each l
o
wer wishbone comprising
forged steel front and rear arms bolted together, incorporates:
A p
ress-fit ball joint in the outer extremity of the rear arm.
Press-f

t bushes for location of the lower fulcrum bolts
Locati
on for the shock absor
b
er lower mounting plates.
Vertica l Links

The vertical
links are of forged steel
wi
th integral steering arms. Each is suppo rted between the upper and lower wishbones
by two ball joints and carries:
Front hub

Brake ca
liper and disc shield assembly

ABS se

Front Hub
s

Each f
o
rged steel front hub accommodates sealed for life cartridge
type wheel bearings, and carries:
The brake rotor assembl
y.
A

Su

Springs
The road spri

een the spring and the crossb eam and the spring pan.
Front Shock A
bsorbers
Th
e
shock absorbers are telescopic hydrau
lically operated units. Optional adaptive damping units incorporate a solenoid-
operated control valve at their upper extremity.
Each shoc
k absorber is installed between the lowe
r wishbone rear arm and a recess in the body.
The l
o
wer end of the shock absorber is se
cured to plates on the wishbone by a bolt that also serves as a pivot.
The u
pper en
d of each shock absorber is secured to the body location by a single nut.

A
front stabil
izer bar installed on all vehicles
is rated according to suspension specification.
Opera
tion
As each road wheel r
i
ses, move
ment is transmitted through the vertical link assembly to the lower wishbone. The resulting
rise of the wishbone compresses the road spring and partially telescopes the shock absorber. During this action, the spring
absorbs associated shocks and the shock absorber minimizes sprin
g os c
illation.

Du

ring cornering, vehicle weight
is transferred to the outer road wheel with a resulting tendency for the inner wheel to lift.
The stabilizer bar assists in minimizing this tendency by transf erring a proportion of potential lift of the inner wheel to the
outer wheel. This result s in enhanced body stability with improved corner ing capabilities.

Description
The i
ndependent rear suspension incorporates co-axial sp
ring and shock absorber units, a subframe, wishbone tie,
pendulum assembly, mounting brac ket, differential strut, cast wishbones and hub carriers. The suspension assembly is
positively located by the subframe, mounting bracket and differential strut.
Each wi
shbone pivots on a fulcru
m bolt which locates in the wishbone tie and pendulum assembly.
The wish
bone tie and pendulum assemblies are respectively in
stalled at the front and rear of the final drive housing.
The differential
strut is secured to the wishbone tie assembly.
Two ti

e rods are installed between the front of the
subframe and the top of the final drive housing.
The ou
ter extremity of each wishbone
is secured to its respective hub carrier assembly by a fulcrum bolt.
Each fulcrum bolt head incorporates an ec centric circular flange which locates in a groove in the front face of the wishbone
arm. Rotation of the fulcrum bolt results in horizontal movement of the bolt shank in an elongated hole in the rear of the
wishbone arm. This acti on achieves corresponding movement of the hub carrier, facilita ting adjustment of road wheel toe-
in.
