Caster Adjustment

WARNING: This page does not describe the selected car, but rather 29 other vehicles, including the 1988 Pontiac 6000, 1988 Oldsmobile Cutlass Cruiser, 1988 Oldsmobile Cutlass Ciera, 1988 Chevrolet Celebrity, and 1988 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
  1. Caster is the tilting of front steering axis either forward or backward from vertical, as viewed from the side of vehicle. See Fig 1 .
  2. When axis is tilted backward from vertical, caster is positive. This creates a trailing action on front wheels. When axis is tilted forward, caster is negative, causing a leading action on front wheels.
