Rear

Description
The independent rear suspension incorporates co-axial spring and shock absorber units, a subframe, wishbone tie, pendulum assembly, mounting bracket, differential strut, cast wishbones and hub carriers. The suspension assembly is positively located by the subframe, mounting bracket and differential strut.
Each wishbone pivots on a fulcrum bolt which locates in the wishbone tie and pendulum assembly.
The wishbone tie and pendulum assemblies are respectively installed at the front and rear of the final drive housing.
The differential strut is secured to the wishbone tie assembly.
Two tie rods are installed between the front of the subframe and the top of the final drive housing.
The outer extremity of each wishbone is secured to its respective hub carrier assembly by a fulcrum bolt.
Each fulcrum bolt head incorporates an eccentric 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 action achieves corresponding movement of the hub carrier, facilitating adjustment of road wheel toe-in.
Each road spring and is located between the wishbone integral spring seat and the body suspension turret,
Each shock absorber unit is installed co-axially within the road spring.
The lower end of each shock absorber is secured to the wishbone by a bolt which also functions as a pivot.
Adaptive damping is available as an option.
A rear stabilizer 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.

Operation
As each road wheel rises, movement is transmitted through the hub carrier assembly to the wishbone and axle shaft. The corresponding rise of the wishbone compresses the road spring and partially telescopes the shock absorber. During this action, the spring absorbs resulting 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 vehicles, 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.
