Frequently Asked Questions: OE 15831813-00
My old hub carries a different number. Does that rule this one out?
No. This assembly carries the OE number 15831813-00 and is also known as UKEA-3104100BS. Suppliers mark parts to their own scheme, so the reference you can read on the unit already fitted may be either of those. Wipe the face of the old hub and read what is stamped there, then compare it against both numbers shown on this page. Where the marking has corroded away or was never legible, use the fitment table on this page against your own model, and send us your vehicle details if you want that checked before ordering.
Can I change a rear hub assembly myself?
This item is safety critical and it sits in the wheel hub and bearing group, so we ask for it to be fitted by a qualified workshop with proper support and tooling. The workshop should follow the vehicle manufacturer data for the BYD Song Ultra EV. If you are ordering on behalf of a garage, pass them the OE number 15831813-00 so they can compare it with the unit coming off the car.
When will this hub assembly arrive?
Delivery takes 8 to 25 days from your order to your door. Tell us your deadline in the order notes if the car is booked into a garage, and we will flag anything that will not meet it. 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 15831813-00.
What is this hub assembly made of and what does that mean for me?
The material used for this hub assembly is metal and the unit is supplied New. Keep it in its packaging until the car is booked in, so that the machined faces are not knocked about in a boot or on a bench. When it is opened, check the OE number 15831813-00 on the label against the unit coming off the car before any work starts.
Whereabouts on the car does this fit?
The position for this assembly is the underbody, at the rear of the car. No left or right side applies to this part, so the item is not split into a nearside and offside version. Work on it from below with the car raised and the rear wheel off. Confirm that what you are replacing sits in that rear position rather than at the front before you order, since a front unit would carry its own OE number. The fitment table on this page lists the models this part fits.
Why is there only one version of this hub listed?
One tier is available for this part, the Original/Genuine unit from BYD. No Aftermarket version is priced for it, which is why the page shows a single option rather than a pair. That is a statement about what we currently have priced, and not a comment on the part itself. If you would like us to look for an aftermarket equivalent, send the OE number 15831813-00 and the details of your BYD Song Ultra EV through the quote route on this site, and we will tell you what can be sourced for it.
