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.

Each r
oad spring and is located between the wishbone in
tegral spring seat and the body suspension turret.
Each shoc
k absorber unit is installed
co-axially within the road spring.
The lo
wer end of each shock absorber is secured to the
wishbone by a bolt which also functions as a pivot.
Adaptive damping is av
ailable as an option.
A
rear stabi
lizer bar is installed on
Supercharged and Sport Suspension models . Mounted at the rear of the wishbone
tie assembly, the stabilizer bar is connected to the wishbone by short links.
Op era
tion
As each road wheel r
i
ses, move
ment is transmitted through th e hub carrier assembly to the wishbone and axle shaft. The
corresponding rise of the wishbone compre sses the road spring and partially telescopes the shock absorber. During this
action, the spring absorbs result ing shocks and the shock absorber minimizes spring oscillation.
During cornering, vehicle weight is transferred to the outer road wheel with a resulting tendency for the inner wheel to lift.
On Supercharged and Sport Suspension vehicl es, a rear stabilizer bar assists in minimizing this tendency by transferring a
proportion of potential lift of the inner wheel to the outer wheel. This results in enhanced body stability with improved
cornering capabilities.

CAUTI
ON: Replacement of
nuts and bolts: Various thread-locking devices are used on nuts and bolts throughout the
vehicle. These devices restrict the number of times a nut or bolt can be used. See section 100-00 for information.
