What Causes Vehicle Steering Pull?

[LaCarlos]

Here are the specific reasons for vehicle steering pull: 1. Changes in wheel alignment data: Variations in wheel alignment parameters can cause steering pull, especially for vehicles frequently driven on rough roads where alignment settings are prone to change. Steering pull is mainly related to the front wheel camber angle. If the camber angles of the two front wheels are inconsistent, the vehicle will pull toward the side with the larger camber angle. 2. Abnormalities in the steering system: For example, bending or deformation of the steering knuckle arm or steering knuckle can generally cause the vehicle to pull to one side. The most severe case is when the tie rod end ball joints are severely worn and become loose, which can lead to steering failure, causing the vehicle to lose control completely. 3. Suspension system faults: If the front shock absorber springs are deformed or one side fails, it can result in uneven suspension height and unbalanced force distribution, leading to steering pull.
