Frequently Asked Questions: OE 15678430-00
Is this the right hand arm, and how do I be certain?
It is the right hand front lower arm. Decide the side while sat in the car facing forward, not stood at the front of it. Then check the reference on the arm coming off against the OE number 15678430-00 given here. If you want the left hand side as well, or instead, work from the fitment table on this page.
My car is a similar BYD but not the one named. Will it still fit?
Treat that as unknown until it is checked. This reference is catalogued against a single model, the Sealion 05, and the fitment shown here has not been extended past it. Nothing on this page supports fitting it to another car, and appearance is not evidence, since handed suspension parts from different models can look alike in a photograph. Rather than order and hope, send a photograph of the old part and its label with the OE number 15678430-00 through the quote route on this page. We will tell you whether this arm is listed for your car.
There is a different reference on the part I removed. Does it match this?
It may. The right hand arm carries the reference TA79-2904020AA as well as the OE number 15678430-00. Read every character before you decide, because the left and right arms are held under separate references. If the number on your part matches either of the two shown on this page, you are looking at the right listing. If it matches neither, or the casting is too far gone to read, send what you have through the quote route on this page and we will do the identification for you.
Does this need a professional to fit it?
This part is flagged safety critical, so the honest answer is that it belongs with a workshop. That flag is there because of where the part sits on the car and what depends on it, and it is not a judgement about your ability. We do not publish a fitting method or any figures on this page, and a general procedure found elsewhere is not a substitute for the one written for your model. Order the arm here and let the garage work to that.
How does the delivery timing work on this one?
Two cases. Allow 8 to 28 days for delivery, counted from your order to your door. Suspension work usually needs a booked slot and a ramp, so settle which case applies before you take the booking rather than afterwards. The quote route on this page is the quickest way to get the current position on this OE number confirmed. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What material is this and how does it arrive?
It is metal, black, and supplied in new condition rather than reconditioned. Inspect the mounting faces and the bushing points when you unpack it, before the car goes on the ramp, because that is easier than finding a problem with the old arm already off. Check the fitment table on this page before ordering.
Why can I not pick a cheaper version of this arm?
There is not one to pick. This reference exists in the Original/Genuine tier only, made by BYD, and no Aftermarket arm has been catalogued against it, so the page shows a single option. Given the part is flagged safety critical, an unverified substitute is not something we will put on the page to fill the gap. If you want the search widened, send the OE number 15678430-00 or the reference TA79-2904020AA through the quote route on this page and we will come back to you.
