Which part of the vehicle typically requires frame alignment after an accident?

After an accident, the part of the vehicle that typically requires frame alignment is the unibody or frame structure. This component serves as the backbone of the vehicle, providing structural integrity and support for all other major parts, including the engine, suspension, and body panels.

When a collision occurs, the frame can become bent or misaligned due to the impact force. This misalignment can lead to issues such as uneven tire wear, compromised handling, and difficulty closing doors and hoods. Proper frame alignment is crucial to restore the vehicle's structural integrity and ensure safe operation.

Addressing only the body panels or suspension system without aligning the frame would not fully resolve underlying structural issues stemming from the accident. Therefore, correct frame alignment is essential for the overall performance and safety of the vehicle post-repair.
