It can also be used to describe the cause of damage to mechanical components such as motor mounts or front suspension as the result of a rear end collision. This type of damage has often been referred to as Kick Up or Kick Down.

An example of this type of damage is if the rear end of a car is out of dimensional tolerance as the result of a front end impact. It is caused by the inertia forces present during a collision. INDIRECT SECONDARY INERTIAL DAMAGE: The damage to the opposite end of a vehicle from which the primary damage occurred. This type of damage generally occurs to parts that are welded or joined to the parts receiving the primary impact of a collision. The damage is a result of the impact to another component that was directly hit in the collision. It has sometimes been referred to as a pre-pull or pull prior to replacement.ĭIRECT SECONDARY DAMAGE: A condition to a firewall, floor pan or other similar component in which the component is pushed back due to an impact to a frame rail or apron.

As a result the cross members are pushed out of a right angle with the side rail.ĭIMENSIONAL PULL FOR STRUCTURAL REPLACEMENT: The dimensional correction to a structural member prior to the replacement of that member. Also is used to describe the repairs to a spliced rail or component that hide the splice or seam to return the component to a factory type appearance.ĭIAGNOSE DAMAGE: The process of actually measuring the control points of a damaged vehicle and determining which ones are not dimensionally correct.ĭIAMOND: Frame misalignment resulting from a heavy impact on the corner of either side rail of the frame that is sufficient to push the side rail back. This condition has often been referred to as banana.ĬONTROLLED DIMENSIONING: The process of aligning a suspension mounting point, arm or other control point or bracket which may not be a part of the actual frame rail but is crucial to proper wheel or body alignment.ĬOSMETIC RESTORATION: The process of restoring the factory appearance to a repaired rail, apron, pillar, rocker panel or other structural component.

It is normally due to a hard impact to the side of the vehicle. An example of this type of damage is if a vehicle is high in the left front, low in the right rear and the rocker panels are not parallel to each other.īUCKLE: A condition to a frame rail, reinforcement or apron from which a visible compression from stress is evident.ĬENTERLINE BOW: A condition in which the center section is out of tolerance to the vehicle center line. A bend can normally be repaired without any permanent deformation to the metal.īODY TWIST: A condition to a unibody in which the datum plane of the vehicle is out of specifications from side to side and front to rear. The damage to a component has no sharp edges on the damage and forms a smooth transition from the undamaged area to the damaged area. ACCESS OPENING: The process of cutting an opening or hole in the back side of a panel or rail to gain access to a buckle or deformation in the metal for repair purposes.ĪNALYZE REPAIR PROCEDURES: The process of using the information from the measurements obtained as well as the information from a visual inspection to formulate a repair plan in which the structural integrity will be restored to the vehicle.īEND: Damage to a frame rail or structural component in which the component is out of correct dimensional specification but is not severely weakened.
