About This Part
Front wheel hub unit assembly for the BYD Sealion 06 EV, including the 2026 model year (2024-2026), OE 18518735-00 with reference UDEA-3103100S. This sealed hub bearing carries the road wheel on the front axle and integrates the flange and bearing in one serviceable unit. Fit it as a pair where possible when you hear a droning wheel bearing, feel play at the hub, or a wheel-speed fault appears. This is a safety-critical suspension part, so torque the hub and axle fasteners to the BYD specification.

Frequently Asked Questions: OE 18518735-00
What do I do if the number on my old part is different from this one?
If the number on your old hub does not read 18518735-00, treat that as a mismatch rather than a close match. This unit is fitted at the front, underneath the car, and a hub built for a different reference will not fit correctly even if it looks similar in your hand. Rather than guess from appearance alone, work through the fitment table on this page and check your vehicle details against it before you place the order, so the part that arrives is the one your car actually needs.
Should this be fitted by a professional?
Fitting a front wheel hub bearing unit involves suspension components underneath the car, so this is not a job to start without the right equipment and know-how. Before anything else, look at the number stamped on the hub you are removing so you know exactly what you are dealing with and can hand that information to whoever carries out the fitting. Getting that number confirmed first means less time under the car and less chance of the wrong part being ordered twice.
What is the front wheel hub unit made of?
It is made of metal, built as a hub bearing unit for the front of the BYD Sealion 06 EV. If you are trying to match it against a part with a different reference on the box, check it against UDEA-3103100S, which is how this same unit is also listed. Matching either number confirms you have the right part before you order, so keep the old unit or its paperwork to hand while you check.
Where on the car does this hub go?
Front and fitted underneath the car is what the listing itself tells you, since this sits within the wheel hubs, bearings and steering knuckles part of the suspension. That does not confirm which side of the car it is for, so before ordering check the side, the position and the fixings on your own car against the unit you are taking off. Match those details alongside the OE number 18518735-00, so the part in the box is going on at the right corner of the car.
