Hi,

I'm hearing some humming sound from my rear tires and it get's louder when I slightly turn my steering wheel to the right. O'm thinking it's my rear wheel bearing.

I'm about to replace my Rear (driver side) wheel bearing "DIY" and whenever I search online for this bearing they are just showing me two different items. Some sites shows two wheel bearings (inner and outter). It looks like a rounded thing with ball bearing in between but there are some online stores that is showing one bearing only (round one with no ball bearings in between just like a colored gel) so I'm really confused which one to get.

Would anyone know the right part number for this type of wheel bearing or website that will provide me the right item and can give me atleast some pictures to look at? My Audi is an 2000 A4 Quattro 2.8 V6 engine.

Would greatly appreciate any help
Thanks
