How to detect a faulty frame side rail?

In most cases, the frame side rail cannot be inspected without removing it from the vehicle. Therefore, unassisted assessment of the state of the component is usually limited to examining the geometry of the car body. Make sure that all doors close with the same force applied, and are at the same level relative to the car body. Then, using a measuring tape, measure the distance between the shock strut mounts, the wheel track width, the diagonals of the doorways, and compare the results with the data specified in the technical documentation to the vehicle. More detailed check will require special test benches; therefore, it is best to seek the assistance of a service station.
