How to Repair the Car Longitudinal Members

Model: (Various brands) Various
Part: Body

Video tutorial

The longitudinal members are steel profiles placed longitudinally on the vehicle, both at the front and rear of the monocoque body. These elements may have slight curves or angles to absorb energy as effectively as possible in the event of a collision.

If the vehicle suffers a significant accident with considerable deformations to the body, to repair the chassis, particularly the longitudinal members, it is necessary to use a measuring bench that allows comparison with the manufacturer's design specifications to restore the exact dimensions and alignment of the chassis as specified in the design.

To do this, the so-called "pull" is used to elongate and reshape the longitudinal members to return them to the design dimensions.
