Is a bent axle on 2000 Silverado 1500 2WD unusual?

Yes, bent axles are not common on 2000 Silverado 1500 2WD trucks. Axles are typically very strong components and are not easily damaged. However, bending or damage can occur if the vehicle is subjected to excessive force, such as hitting a curb or pothole at a high speed, driving over rough terrain, or overloading the vehicle beyond its rated capacity. If you suspect your axle may be bent, it is important to have it inspected by a qualified mechanic as driving with a bent axle can be dangerous and can lead to further damage to the vehicle.
