Rear Axle: Notes
Rear Axle: The rear axle is designed with kinematics, aerodynamic features and also houses the differential. This suspension system incorporates anti-dive (when braking) and anti-squat (when accelerating) geometry which keeps the vehicle level.
Kinematics relates to the suspension system design type. The term implies flex, which in fact the system does. Under load (acceleration, turning, braking), the suspension changes its geometry to counteract changes induced by the increased loads. The suspension changes are pre-determined and built into the system.
Rear Axle Carrier: The rear axle carrier is a welded structure made of formed aluminum sections and cast aluminum joints. The differential is mounted in the rear axle carrier, with two mount points at the front and one at the rear.
This offers advantages regarding sound and vibration characteristics. The rear rubber mount features kidney-shaped recesses allowing for vibrations in horizontal or vertical direction.
Refer to the Repair Instructions for correct removal and installation.
Control Arms and Links: The control arms and links are aluminum and are geometrically adapted to the E65.
When the rear suspension is in the normal position, it is aligned parallel to the road and creates the desired air flow to the rear of the vehicle.
Stabilizer Bar: The stabilizer bar is designed as a tubular stabilizer bar, which minimizes body "roll" during cornering. It is connected by links between the rear axle carrier and the control arms. The connection at the control arm is an axial ball joint which is secured by a taper seat and Torx bolt. The active roll stabilizer bar (ARS) will be covered in Dynamic Drive.
