wheel bearing?

Hey, i get this sound from the back of my car that sounds like a jet engine, or i have super swampers on, i think my wheel bearing is bad, does anyone know if it can be changed out with hand tools or how hard it is to do?

You need a slide hammer with a puller attachment. You have to pull the hub off to replace the bearing. The best thing to do is go to a large auto parts store and buy a complete slide hammer puller kit for around $ 60.00 . Everything you need should be in the kit. You can rent them from some auto parts stores if you don’t want to spend the cash to buy it.
