Frequently Asked Questions: OE 18468531-00
Why does this only fit one model, and what if my BYD is a close match but not exact?
This subframe is listed for one specific fitment, with OE number 18468531-00, also shown as UNEA-2810120A. If your Sealion 05 EV is not an exact match, find the number stamped on the subframe you are taking off the car and compare it against these two references before ordering. That stamped number is the surest way to confirm you are buying the right one, since the listing here covers only this single fitment. Do not guess from the model name alone, work from the number on the old part.
The number on my old subframe does not match 18468531-00, what now?
Do not fit it on the strength of the description alone. Open the photographs on this page and compare the casting against your old subframe before ordering, checking the mounting points and the overall shape. If anything looks different from what you have removed, hold off and check again rather than guessing. This is listed under the OE number 18468531-00, also shown as UNEA-2810120A, so check both against any marking you can find on the old part.
Can I fit this front subframe myself or should someone else do it?
Use the quote route on this page and have a professional price the fitting alongside the part. This is a full subframe assembly for the BYD Sealion 05 EV, fitted underneath the car at the front, and getting a price for both together means you know the full job cost before anything is ordered. Check the OE number on your old subframe against the one listed here first, then get the fitting quoted at the same time.
How does a part this size get delivered to me?
The packaging details are shown on this page. Delivery time is confirmed with your quote. Check the fitment table on this page before ordering, so the part that arrives is confirmed for your Sealion 05. The shipping cost is confirmed with your quote. Before you order, check the number on your old part against OE 18468531-00.
Is this subframe metal or some kind of composite?
It is metal, finished in black, and supplied new rather than reconditioned. Because it forms the main structural mounting point under the front of the car, check it against the side, the position and the fixings on your own vehicle before ordering, since a subframe fitted to the wrong side or the wrong mounting points will not line up. The OE number is 18468531-00, also listed as UNEA-2810120A. Confirm both against the number on your old part first.
Where does this subframe fit on the car?
This is the front subframe, the main structural assembly under the front of the car that carries the suspension and mounts to the body. Before you order, have the old part off the car and check the OE number 18468531-00 against it, or the alternative reference UNEA-2810120A. It is fitted underbody and made of metal, so it is not a small job to swap. Confirming the number against your old subframe first means the one that arrives is the one your car actually needs.
