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 Tahoe/Suburban.
The full 2017 Chevrolet Tahoe OEM Partial Part Replacement Search page, and the 2017 Chevrolet Suburban 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.
Both the Tahoe and Suburban have a single procedure for sectioning the front lower rail. This procedure requires replacement of both the left and right frame rails, along with the crossmember between them. Chevrolet does not have a procedure for sectioning or partial part replacement for the rear rails, full part replacement is necessary.
There are multiple sectioning procedures for the outer uniside, including the outer A-pillar, B-pillar, and quarter panel. The sectioning joint for the outer uniside is a lap joint that uses a 25 mm overlap.
