When is frame straightening typically necessary?

Frame straightening is typically necessary after a substantial collision because such events can cause significant structural damage to a vehicle's frame. When a vehicle experiences a strong impact, the frame can become warped or misaligned, which affects the overall integrity and safety of the vehicle. This misalignment can lead to issues with handling, tire wear, and can compromise the effectiveness of safety features, making it vital to assess and, if necessary, straighten the frame.

In contrast, regular maintenance does not typically involve frame straightening since it focuses on routine checks and services to keep the vehicle operational. Following a minor dent, the damage is usually cosmetic and does not affect the frame's structural integrity, thus not requiring any straightening. When a vehicle is being painted, the frame's condition is generally not the focus area, as painting addresses the outer surface of the vehicle rather than the underlying structure. Therefore, the need for frame straightening is primarily linked to major impacts, making it crucial to ensure the vehicle's safety and performance after a substantial collision.
