Ok so today i tore apart both rear drums and brakes and need to replace my rear wheel bearings. I Have a 2004 Aveo. I have called a couple parts store and Everyone is telling me it's a single bearing, but I'm looking at my bearings now and I don't understand how it can just be one. there is a tapered bearing that comes out of the brake drum and there is a seperate on that is pressed into the brake drum. My question is, is it just a single bearing that has broken, or is it 2 seperate bearings. please help.
