UNITIZED STRUCTURAL BODY REPAIR | 2025/2026
UPDATE | QUESTIONS AND ANSWERS | WITH
COMPLETE SOLUTION!!
Unibody Answer - Lightweight stamped sheet metal components that are
welded to each other to create a single unit.
Space Frame Answer - Body panels can be made from plastic are steel. Steel
may be Mild, Intermediate, or HSS. Panels may hide damage to frame or
structure.
Crush Zones Answer - Structural components such as rails are designed to
collapse and bend at specific points.
Collision Energy Management Answer - Goal is passenger protection. Front
and rear structures act as crush-able energy absorbers.
Direct Damage Answer - POI. Easily located and diagnosed.
Indirect Damage Answer - transmission of collision energy beyond the area of
immediate impact. Examples; Split seam sealers, pulled spot welds, misaligned
panels, buckles in steel, cracked glass, and cracked or chipped paint.
Passive Restraint Systems Answer - Must have service manual. No two are
alike.
, Datum Answer - Imaginary plane or line beneath the vehicle. Measures height.
Centerline Answer - Vertical plane that passes from the front of the vehicle to
the rear. Measures Width. May have stamped marks on vehicle body structure.
Is confirmed by referencing at last 3 width measurements in the undamaged
portion of the vehicle.
Zero Planes Answer - Vertical plane that passes from side to side. Confirmed by
measuring 3 length measurements from the undamaged portion of the vehicle.
Symmetry Answer - Equal on each side of the vehicle.
Asymmetrical Answer - Unequal on each side of the vehicle. (spare tire well)
Reference Points Answer - Bolts or nuts, Holes, Mechanical attachment points,
Edges of panels, Door strikers, Corner of openings. Common tolerance is
=/.3mm (1/8) or all the way to 1mm (1.32).
Loaded Measurements Answer - Drivetrain In
Unloaded Measurements Answer - Drivetrain out
Point to Point Measurements Answer - shortest distance between 2 reference
points. AKA "as the crow flies". Uses tram or steel tape measure.
Datum Measurements Answer - Taken at Datum plane, height differences
between reference points. Laser measuring system
