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 2017 Lexus RX 450h.
The full 2017 Lexus RX 450h 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, Lexus has a paid subscription website with collision repair information.
The RX 450h has a single sectioning location on the front lower rail just before the firewall. There are multiple areas with partial part replacement at factory seams procedures. The front lower rail, front upper rail, and rear rail have multiple locations that can be replaced at factory seams. It is important to note that no sectioning is allowed on the upper and rear rail.
The OEM has many sectioning locations available for the outer uniside, uniside reinforcements, and the inner uniside. The sectioning joint for the outer uniside is an open butt joint.
