Back-To-Basics: Three-Dimensional Measurements And Welding With Loaded Suspension
I-CAR · June 18, 2019
Summary
This article highlights the critical impact of vehicle suspension loading and engine presence on three-dimensional measurements and panel fitment. It explains how vehicle flexibility can cause panel gaps to shift or weld-on panels to buckle if measurements and welding are performed under incorrect loading conditions.
What to do on the job
Consult the OEM body repair manual or measuring system specifications to determine whether the vehicle must be measured and welded with a loaded or unloaded suspension, and with or without the engine installed.
How to use it
Use this document to justify the necessary labor time and setup required to properly configure the vehicle's suspension loading and engine status prior to measuring or welding. It serves as an excellent defense against insurers who may question the time needed to simulate a loaded suspension or verify OEM-specific measuring conditions.
