What is a likely cause of difficult steering and a fast steering wheel return?

The scenario of difficult steering combined with a fast steering wheel return is often associated with too much positive caster. Positive caster refers to the angle of the steering axis that tilts backward from the top to the bottom at the front of the vehicle. This design enhances the vehicle's straight-line stability and helps the steering return to center after a turn, which is why you may see a quick return of the steering wheel to its original position.

When the caster angle is excessively positive, the steering can feel heavy and require more effort to turn, especially at low speeds. This is due to increased steering geometry forces that resist motion, creating the sensation of difficult steering. Additionally, the significant self-centering effect of an overly positive caster can lead to a rapid return of the steering wheel after a turn.

In contrast, options involving negative camber and negative caster would not correctly explain this combination of symptoms. Too much negative camber can lead to uneven tire wear and a loss of cornering grip, but not specifically to difficult steering. Excessive negative caster would typically result in a loose or vague steering feel and would not promote a quick steering return. Thus, the characteristics of difficult steering and a fast steering wheel return align with the condition of having too much positive caster
