Frequently Asked Questions: OE 18936865-00
What if the number on my old shaft does not match this one?
Check the model and the model year exactly as printed on your registration document before you order. This shaft carries OE number 18936865-00 for the BYD Seal 05 DM-i, and it also carries the reference HA5H-3404030. If the number on your old shaft matches neither, or your registration document shows a different model or model year, do not fit this part on the strength of a similar looking old shaft. Send a photograph of the old shaft and its label through the quote route and we will confirm it against the OE number before you order.
Can I fit this myself or do I need a garage to do it?
This part is fitted underbody, so check the photographs on this page for the exact shape and end fittings before deciding whether you have the tools and space to do the job yourself. It is listed as new and made of metal, matching OE number 18936865-00. If the photographs show connections or brackets you do not recognise from the old part, that is a sign to have it fitted by a garage. Compare the images closely against your removed part before ordering.
What is the intermediate shaft made of?
It is metal. That is the only material listed for this part, so there is no lighter or composite version to weigh up against it. Check the fitment table on this page against the OE number on your old shaft, 18936865-00, before you order, since steering column parts vary between trims and a close match is not always the right one. If the numbers agree, this is the part to fit.
Where does the intermediate shaft fit and how do I know it is the right one for my BYD Seal 05 DM-i?
It sits underbody, in the steering column, carrying movement down from the wheel. Before ordering, find the shaft you are removing and read its stamped number. This one carries OE 18936865-00, also shown as HA5H-3404030, so match that against your old part rather than guessing from the model name alone. It is made of metal, new, and comes from BYD as the genuine maker. The delivery time is 8 to 25 days, from order to door.
