Wheel Alignment - Specifications & Adjustments: Adjustment: Caster

Generally caster is stated as nonadjustable, and that if not within specifications parts are to be replaced. However, in some instances when slight adjustment will alleviate the problem, adjustment of strut bar nut is permitted. If caster is altered, wheel base must stay within approximately 92.1" (Arrow and Colt; Exc. Colt Wagon) or approximately 99" (all others).
