Frequently Asked Questions: OE 16550946-00
Will this subframe fit my BYD Sealion 05 EV if mine is a slightly different trim or year?
This subframe is made for one model, the BYD Sealion 05 EV, with nothing else shown for it. If your car is a similar model or a later version, do not assume it will fit. Look underneath your own car at which side this part sits, its exact position on the underbody, and how many fixing points hold it in place. A subframe with even one fixing out of place will not line up, whatever the family resemblance between the two cars.
The number on my old subframe does not match 16550946-00, what should I do?
The OE number for this subframe is 16550946-00, also listed as TA79-2810002AA. If the number stamped on your old subframe does not match either of these, do not order on the strength of the vehicle alone. Check the model and the model year exactly as printed on your registration document, and compare that against what is asked for on this page. If the two still do not agree, treat that as a mismatch rather than a near enough. Getting this right first avoids an order for a subframe that was never fitted to your car.
Can I fit this rear subframe myself or does it need a garage?
Yes. This is a structural part of the suspension that sits on the underbody. The car needs to be safely raised and held while the old subframe is removed and the new one is offered up and squared before anything is tightened. Before you order, have the old part in front of you so you can see how it connects to the rest of the car and judge whether you have the means to get it in and out safely.
How does a part this big and heavy get delivered?
The packaging details are shown on this page. Delivery time is confirmed with your quote. Check the photographs on this page to see the scale of what you are ordering before it arrives at your door. It is worth checking the fitment table on this page against your Sealion 05 EV before you order, so delivery is not wasted on the wrong part.
What is this rear subframe made from?
It is metal, finished in black, which is standard for a structural part carrying the weight and loads of the rear suspension underneath the car. Because it sits under the body and takes that kind of load, fitting the correct one matters more than with a trim piece. Before ordering, look at the old subframe you are removing and find its stamped number. Match that against the OE number on this page, 16550946-00, so you know the replacement lines up with what is actually coming off your car.
Where does the rear subframe sub-assembly fit on the Sealion 05 EV?
It sits underneath the car, bolted to the underbody at the rear, carrying the rear suspension components. Because it is a structural part, it needs to be the correct one for your exact car rather than a close match. Check the OE number on your old subframe against the fitment table on this page before ordering. The part is supplied in black metal as a new unit, so no reconditioning or repair of the old one is involved.
