Left Front Steering Knuckle for BYD Yuan UP, OE 15542853-00

The left side, at the front. This one is the left front steering knuckle, and the right-hand version is sold under its own OE number. On a UK road car the left is the nearside, the kerb side as you drive. The quickest check is to look at the corner you are replacing while facing forward from the driver's seat. A left part will not serve on the right, so be certain of the corner before ordering. The fitment table on this page shows which vehicles the left one fits.

Because it is offered in both tiers. The Original/Genuine version is the BYD item for OE 15542853-00. The Aftermarket version is an equivalent made by another supplier and carries its own price on this page. Both are new stock and both sit against the same fitment for the left front corner. Pick on budget and on how strongly you want the BYD branding, then select the tier before checkout. If a workshop has specified one line or the other, follow that rather than defaulting to the cheaper option.

Yes. Markings sit on the casting and can be hard to read once the corner has been on the road a while, so wipe the area down and check under a light. If the number you find matches neither reference, do not guess. Send the reading through the quote route and we will match it against the fitment data. Keep the old left front steering knuckle (service kit) until the new one is fitted, in case the two need comparing.

This part is safety critical, so the honest answer is that it belongs with a qualified technician. It mounts underbody at the front, so the car must be raised and supported before the corner comes apart, and the corner then has to be reassembled correctly. We do not have a fitting procedure or torque figures for it, and we will not invent any, so your garage should use the vehicle manufacturer's information. If you are buying the part to reduce the workshop bill, book the labour before you order so the dates line up.

The delivery time is 8 to 14 days, from order to door. Use the quote route if you need a firmer date first. 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 15542853-00. If anything about the timing matters for a booked repair, ask through the quote route on this page.

It is metal, in black, and it is new. Keep it in the box until the fitting day so the surfaces stay clean and dry. If the finish is marked when you unpack it, tell us before the part goes near the car. Check the OE number on the old knuckle against the fitment table on this page before you start the job.
