Rear Wheel Hub Unit for BYD Dolphin, OE 12660703-00

This hub is fitted to a wide spread of BYD models, so the badge on the boot lid will not settle it on its own. Open the fitment table on this page and match your own model and build first. Then check OE 12660703-00 against whatever is readable on the hub you are taking off. If your car is not shown in the table, or the marking on the old unit does not agree with the number here, send your model details through the quote route and we will check the fitment before you order.

EL-3104100 is the alternative reference we offer against this hub unit, so a part carrying that marking and a part carrying OE 12660703-00 point at the same item. Either number can end up being the only one still readable on a used part. Clean the old hub, note down every number you can make out, and compare what you have with the two shown on this page. If a third reference turns up that matches neither, send it to us through the quote route and we will check it for you.

This hub unit is safety critical, so we would have it fitted by a garage rather than tackled on a driveway. It sits underneath the car at the rear, which means the vehicle has to be raised and supported properly before anyone can reach it, and that needs equipment most home tool kits do not run to. Book the car in before the part reaches you. That way the old unit can come off and be compared against this one while the ramp time is already paid for.

The delivery time is 8 to 25 days, from order to door. Order before you book the ramp, not after. If you are working to a fixed date, put that date into the quote route with OE 12660703-00 and we will tell you what the timing allows. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12660703-00.

The material for this part is metal, and the condition is new, so this is not a reconditioned unit with a previous life on somebody's car behind it. Keep OE 12660703-00 and EL-3104100 in mind when the box is opened, and compare the part in your hand with the old hub before anything goes near the ramp. If what arrives does not match the description here, come back to us before it is fitted.

The mounting position we offer for this part is underbody, at the rear of the car. Two things follow from that. The job is done with the vehicle raised and supported rather than from standing height, and the position line on the listing matters when you are comparing one page against another. Front and rear items are listed separately on this site, so check that the rear description here is the end of the car you are actually working on. The fitment table on this page will confirm it against your own model.

Only one version is priced on this page. This hub is made by BYD, and no aftermarket equivalent is offered for it, so what you are looking at is the Original/Genuine item and nothing else. That reflects what we can source for this part rather than any policy on our side. Where a second tier does exist we list it alongside the first on the same page. If you would rather be quoted on an alternative, ask through the quote route quoting OE 12660703-00 and we will tell you what is available.
