Caster

CASTER
Caster is the tilting of the front steering axis (at the top) either forward or backward from the vertical. A backward tilt is "Positive" (+) and a forward tilt is "Negative" (-). Caster influences directional control of the steering but does not affect tire wear. Caster is affected by vehicle height, therefore it is important to keep the body at its designated height. Overloading the vehicle or a weak, sagging rear spring will affect the caster. When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a less positive caster.

INSPECTION (CASTER)
1. Position the vehicle so that the front wheel is on the turning-radius gauge.





2. Remove the wheel cover.
3. Attach a standard caster gauge to the hub and measure the caster.
Caster:
3.30° ± 0.5° (No Passenger Load)
3.55° (2 Passenger Load)

ADJUSTMENT (CASTER)
1. Turn the front spindle clockwise until the number "1" mark is aligned with the vertical line on the spindle bracket.





2. Turn the rear spindle counter-clockwise until the number "1" mark is aligned with the vertical line on the spindle bracket.

Each numerical point indicated on the spindle increases the caster by 0.23 degrees when turned to the vertical line.
