The caster angle on the left front wheel is set at 1 degree negative and the right front at 1 degree positive. What is the likely result?

When the caster angle on the left front wheel is negative and the right front wheel is positive, this difference creates an imbalance in the steering characteristics of the vehicle. Caster helps in maintaining directional stability and contributes to the self-centering of the steering system.

A negative caster angle on the left wheel means that the suspension geometry is tilted backward at the top, which can reduce stability and steering response on that side. Conversely, a positive caster angle on the right side indicates that the top of the right wheel is tilted forward, enhancing stability and steering control on that side.

The result of having the left front wheel with negative caster and the right front wheel with positive caster is that the left front wheel will provide less directional stability and may not track as effectively as the right front wheel. As a result, the vehicle is likely to pull to the left, since the left front wheel has a reduced tendency to steer itself back toward the centerline of the vehicle due to the unfavorable caster angle.

This scenario emphasizes the importance of proper alignment settings, as uneven caster can lead to handling issues and uneven tire wear.
