Mechanic performing truck and trailer alignment service from SOS Truck & Trailer Repair

Truck & Trailer Alignment

If you notice your vehicle drifting to the left or right when driving long distances, improper wheel alignment is often the culprit. This can occur if the suspensions, which connect your wheel hubs to the steering knuckle with ball joints, wear down. Out-of-alignment suspensions can cause the wheels to become incorrectly positioned with the rest of your truck. Ultimately, such a situation can damage the wheels, especially when you drive over rough terrain. Also, what if your truck or trailer pulls in a particular direction when accelerating, prompting you to steer to the opposite side? This is a sign that it’s due for a checkup.
