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 Chevrolet Impala.
The full 2017 Chevrolet Impala 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 Impala has no sectioning procedures for the front lower, upper, or rear rail. There is partial replacement at factory seams for the three rails. The front lower rail and upper rail, both have more than one location. Chevrolet allows sectioning in a single location for the trunk floor. The new trunk floor overlaps the remaining trunk floor, and is attached using two rows of plug welds.
The outer uniside has sectioning procedures for the outer A-pillar, B-pillar, quarter panel, and rocker panels. The sectioning joints call for a one inch overlap. There are sectioning locations for the inner uniside. Partial replacement at factory seams procedures are also available for the uniside reinforcements.
