One of the top technical inquiries received at Ask I-CAR, “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 2017 Buick Enclave.
The full 2017 Buick Enclave 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.
The Enclave has options for partial part replacement at factory seams for the front lower and front upper rails.
The rear rail has a sectioning and partial part replacement at factory seam procedure. The sectioning joint is a butt joint with backing. Plug welds are made on both sides of the sectioning joint and then the butt joint is stitch welded.
The outer uniside has multiple sectioning locations. Procedures include outer A-pillar, outer B-pillar, and outer quarter panel. The rear body panel has a full part replacement procedure.
