One of the top technical inquiries received at Ask I-CAR is “Is there a sectioning or partial replacement procedure available?” To help answer this question, RTS has an OEM Partial Part Replacement Search that tells you if these procedures are available on a specific vehicle. Let’s take a closer look at the 2018 GMC Acadia.
The full 2018 GMC Acadia OEM Partial Part Replacement Search page is on the RTS website. This gives you a good understanding of general areas for sectioning or partial replacement. I-CAR does not have permission to show exact locations for sectioning or the procedure itself. However, GMC has paid subscription website with collision repair information.
There is a partial part replacement at factory seams on the front lower rail. There is also a procedure(s) available for partial part at factory seams for the front upper rail. The rear rail has a single location for both sectioning, and partial part replacement at factory seams.
Multiple sectioning locations are allowable on the outer uniside. Per the 2018 GMC Acadia Body Repair Manual: "Note: Squeeze Type Resistance Spot Welds equivalent to the factory spot welds are recommended. If access to use Squeeze Type Resistance Spot Welds is not possible, MIG/MAG 8 mm (5/16 in) plug welds may be used, to replace those specific welds."
There are OEM sectioning procedure(s) available in the body repair manual for the rear body panel. A single partial part replacement at factory seams and a sectioning location is available for the trunk floor. No sectioning is available for the uniside reinforcement and inner uniside.
