One of the top technical inquires 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 Chevrolet Silverado.
The full 2017 Chevrolet Silverado 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 Silverado has a single procedure for partial replacement at factory seams for 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, a full part replacement is necessary.
There are multiple sectioning procedures for the outer uniside, including the outer A-pillar, B-pillar, and rocker panel. The sectioning joint for the outer uniside is a lap joint that uses a 25 mm overlap.
