Wheel Alignment Angles: Caster
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Caster is the deviation from vertical of an imaginary line drawn through the pivot points (top of strut and lower ball joint), when viewed from the side. The caster specifications in this article will give the vehicle the best directional stability characteristics when loaded and driven. The caster setting is not related to tire wear.
| Item | Description |
|---|---|
| 1 | True vertical |
| 2 | Positive caster angle |
| 3 | Strut-to-ball joint centerline |
| 4 | Pivot centerline |
A backward tilt is positive (+) and a forward tilt is negative (-). Front caster adjustment is not a separate procedure on this vehicle. Front caster should fall within specification when the front camber is adjusted.
