Frequently Asked Questions: OE 12660709-00
Will this front wheel bearing fit my car?
Match your car in the fitment table on this page before you order anything. This bearing fits a broad range of BYD models, and the model name on its own will not settle the question, because build and variant change what was fitted. Work from OE 12660709-00 first, and check it against the marking on the bearing or hub you are removing. Where the old part carries nothing readable, send a photograph of the old part and its label through the quote route and we will check it for you.
The reference on my old bearing is EL-3103110. Does that match this listing?
It does. EL-3103110 is the alternative reference for this bearing, and it sits beside OE 12660709-00 for the same part. A used bearing will often show only one of the two once the grease is wiped away, and the alternative reference is frequently the easier of the pair to read. Write down whatever you can make out on the old part and compare it against both numbers given here. If neither one agrees with what you are holding, ask us through the quote route rather than ordering on the strength of the model name.
Is this something I can fit at home?
We would not suggest it. This bearing is safety critical and it sits underneath the car at the front, so the vehicle must be raised and held properly before the work can even start. That rules out most home setups. Have a garage do it, and ask them to check OE 12660709-00 against the old part while the car is still in the air. Delivery takes 8 to 25 days from your order to your door.
When would this bearing reach me?
The delivery time is 8 to 25 days, from order to door. If a date is fixed for you, tell us in the quote route and we will confirm what fits. 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 12660709-00. If anything about the timing matters for a booked repair, ask through the quote route on this page.
What is the bearing made from, and does that matter to me?
Metal is the material for this part, and the condition is new. For a buyer that mostly settles what turns up in the box: a new metal component, not a cleaned up used one. Leave the part sealed until the car is on the ramp, and open it in front of whoever is fitting it.
Whereabouts on the car is this bearing fitted?
It is an underbody part at the front of the car, which is what the position lines on this listing record. Nothing about it is reachable with the wheels on the ground. That has a bearing on how you buy it as well as how it goes on, because front and rear items are held under separate listings here and the two are ordered by different numbers. Read the position line together with the fitment table on this page, and be sure the end of the car described here is the end you are working on.
Is there an aftermarket option for this bearing?
Not on this page. BYD is the manufacturer for this bearing and there is no aftermarket equivalent for it, so the Original/Genuine version is the only one we can price here. Where both tiers exist for a part they appear side by side on the same page, and you choose between them at the point of ordering. Since that choice is not available here, the decision is simply whether this item is the right reference for your car. Use the quote route with OE 12660709-00 if you want alternatives looked at.
