Which system would likely cause a vehicle to pull to one side if misaligned?

A vehicle pulling to one side is most commonly linked to issues within the wheel alignment system. When the wheels are not aligned properly, it can lead to uneven tire wear and affect handling. The alignment involves adjusting the angles of the wheels so that they are perpendicular to the ground and parallel to each other. If these angles are off, it can cause the vehicle to drift or pull in one direction when driving straight.

Misalignment might occur for various reasons, such as hitting a pothole or curbing the wheel, which can disturb the careful angling of the suspension components. Proper wheel alignment is crucial for ensuring even tire wear and safe handling characteristics. Therefore, when a vehicle pulls to one side, checking the alignment is a logical first step in diagnosing the problem.

While other systems like the brake, suspension, and steering could also impact handling and directionality, they primarily do not cause the same direct effect on pulling unless there are more severe issues at play, such as a stuck caliper or severe wear in suspension components. In contrast, the alignment itself is the most straightforward and common cause related to this particular symptom of pulling.
