Frequently Asked Questions: OE 12778045-00
How can I check this hub unit is right for my car?
This hub unit fits a number of models rather than one, so the fitment table on this page is the part to read before you order. Check your model and its build year against the table, and note that the front axle is what this one is for. If your car does not appear, or you are looking at two entries and cannot tell which applies, send the vehicle details and the number from the old unit through the quote route and we will confirm it for you first.
My unit is marked SA2H-3103100. Is that the same as 12778045-00?
It is. Both references point at this same front wheel hub unit, so a different number on the part you have removed is not a sign of a problem. On a hub the number is usually stamped or etched into a machined face and can sit under a layer of road dirt, so clean it up before you decide it is unmarked. If either reference matches what you find, this is the right listing. If neither does, send a photograph of the marking and your vehicle details through the quote route.
Should this be fitted by a professional?
Our data flags this one as safety critical, which is our way of saying it belongs with the items we would want a qualified technician to fit rather than something tackled on a driveway. The work around a front hub unit involves fasteners and settings that have to be done properly, and it is not the place to improvise. If you are buying the part to hand over to a garage, that is exactly the right approach. Before you order, check the OE number on the unit currently on your car.
How long does this take to arrive?
Allow 8 to 25 days for delivery, counted from your order to your door. Both periods matter when you are booking the car in, because the garage will want the part in hand before the wheel comes off rather than halfway through the job. If you are working to a fixed date, raise it with us through the quote route before ordering and we will tell you what the position is for your delivery address.
What is this hub unit made of?
Metal is the material used for this part. Unwrap it and look over the machined faces before it goes anywhere near the garage, since those are the surfaces that matter. Compare it with the unit coming off your car, and if the two look meaningfully different, check the numbers on both against the references given here.
Where does this sit on the vehicle?
This unit sits on the underbody of the car at the front, so the vehicle has to be raised and the wheel taken off before anyone can reach it. Factor that into the job before you order, particularly if the work is going to a garage that charges by the hour. Confirm your model in the fitment table on this page first, and read the number off the old unit while it is accessible. If anything is unclear at that point, use the quote route.
Why is there no Aftermarket hub unit here?
Only the Original/Genuine hub unit from BYD is listed under this OE number. No Aftermarket version of 12778045-00 is available, so this page shows one option rather than two tiers side by side. On a part that is safety critical we would rather list nothing in the second tier than list something we cannot stand behind. If you want an alternative you have been offered checked against this reference, send it through the quote route and we will compare it.
