Inspect pintle hooks and draw bars, if applicable.
Pintle hooks and draws bars deal with excessive stress and should always be closely examined for structural damage. Make sure that all bolts and connecting hardware has no damage. Pintle hooks should have a chain connected with a locking pin. Visually inspect the frame where the pintle hook connects. Any damage should result in the vehicle being deadlined (red tagged).
