Frequently Asked Questions: OE 17204621-00
How do I know this fits the left side and not the right?
This one is listed for the left rear only. The safest way to be sure is not to guess from memory but to look at the old part itself before you place an order, since it will show you straight away which side of the car it came from and how the driveshaft sits in relation to the wheel. Keep the old part to hand while you check the details on this page, so you can compare shape and fitting position rather than relying on what you think you remember.
Why does this only fit one model?
Only the BYD Sealion 05 EV is listed for this driveshaft, and there is no other version to choose from. To be sure it is right for your car, check the model and the model year exactly as they appear on your registration document, rather than the model name you use day to day. If what is printed there does not match this listing precisely, do not order on the assumption that it is close enough.
What if the number on my old part is different?
If the number stamped on your old driveshaft does not read 17204621-00, do not rely on the model name to decide. Go to the fitment table on this page and check it against what is listed there, since that table is the accurate way to confirm the right part for your car. Treat any mismatch in the number as reason enough to check again before you order, rather than trusting the model name on its own.
How is a driveshaft this size delivered to me?
It comes as one metal assembly, so it cannot be broken down into smaller boxes for delivery. The packaging details are shown on this page. Delivery takes 8 to 28 days from your order to your door. If the courier details or tracking reference on the box do not look right when it arrives, check it against the alternative reference UNEC-2201010B, which this part is also listed under, before you sign for it.
