How does the rear suspension on a 1999 Oldsmobile aurora work?

The 1999 Oldsmobile Aurora uses an independent rear suspension of the multilink type. This is not a simple single-arm or leaf spring setup. Instead, it's a more sophisticated system designed for better handling and ride comfort.

A multilink suspension uses multiple control arms (typically four or more) to locate the wheel and control its movement. These arms work together to manage:

* Toe change: How much the wheels angle in or out during suspension travel.

* Camber change: The angle of the wheel relative to the vertical during suspension travel.

* Anti-squat and anti-dive: Minimizing body movement during acceleration and braking.

* Roll stiffness: Controlling body roll in corners.

The specific geometry and arrangement of these links in the Aurora's design are proprietary to GM, and detailed diagrams would be found in service manuals. However, the fundamental principle remains: multiple links working in concert to optimize the wheel's movement and the car's handling characteristics. This type of suspension is generally considered more advanced than simpler designs and provides a more refined driving experience.
