I did a bit of research and it seems like it would cost a lot of money to replace the drums with disk brakes. I went ahead and had a shop fix my bearing issue because I don't have time to deal with it anytime soon. They inspected it and ordered me a new bearing hub assembly like the Duralast/Wheel Bearing/Hub Assembly - Rear (DL512357) | 2005 Chevrolet Aveo 4 Cylinders 6 1.6L MFI DOHC | AutoZone.com from Napa along with two bearings, I believe and had them pressed on. They told me Napa would back it up if anything went wrong and that the shop would also warranty it in case it failed for any reasons. All in all it was $235 for parts and labor. I drove home and it was quiet as can be! I couldnt believe how loud it actually was before! Haha
