Section 83 (Rear Suspension): Spindle: Operation
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
The spindle moves up and down with the tire and wheel under jounce and rebound conditions. The lateral links control lateral movement of the spindle while the trailing arm controls fore-and-aft movement.
The spindle acts as a mount for the rear hub and bearing, tire and wheel, and rear brakes.
