wheelbearing坏了

2002 Silverado. Im not a mechanic but i can usually figure most things out on my own. I can do things like my brakes, rotors, regular maintenance, oil changes, spark plugs etc. Is a wheel bearing pretty easy, meaning like just remove a few screws and pop the new hub in. Or is it more complicated than that and I should just take it to a mechanic?
