If a vehicle has a negative setback, which of the following is a likely outcome?

A negative setback occurs when the angles of the steering axis are such that the steering pivot is positioned behind the vertical centerline of the tire contact patch. This misalignment can lead to uneven steering responses and can cause the vehicle to pull in one direction. Specifically, if a vehicle has a negative setback, it most commonly leads to a pull to the left. This happens because the forces acting on the tire are not balanced, causing the vehicle to favor one side, resulting in this directional pull.

The behavior of the suspension and steering geometry is critical here, as negative setback tends to create an unbalanced condition where one side offers less directional stability. In this scenario, the steering response becomes compromised, leading the vehicle to veer toward the side with the negative setback effect, which would typically be the left side in most cases.

Understanding this dynamic is essential for diagnosing vehicle alignment issues and ensuring proper steering function and tire wear.
