What must be checked when a vehicle sustains an impact to the wheel after a collision?

When a vehicle sustains an impact to the wheel after a collision, it is crucial to check both the wheel alignment and the condition of the axle. After a collision, the dynamics of the vehicle can change significantly, which may result in misalignment of the wheels. Proper wheel alignment is essential for vehicle stability, even tire wear, and accurate steering response.

In addition, the condition of the axle must also be assessed. The axle plays a vital role in connecting the wheels to the vehicle and enabling them to rotate. An impact can cause bends or damage to the axle, which may not be immediately visible. This can lead to unsafe driving conditions and further mechanical issues if not addressed.

Focusing solely on alignment or axle runout ignores critical aspects of the vehicle's safety and performance after a collision. While examining the brake system is also important after an impact, it is not directly related to the effects on the wheel and axle that are the primary concerns in this scenario. Thus, ensuring both the wheel alignment and the axle's condition are verified is essential for the overall safety and functionality of the vehicle.
