So I busted a stud off on my front wheel hub while rotating the tires, and since it's only a 4 lug hub, I thought I'd better replace it . In addition I have over 170k miles on the car, so I'm thinking I should go ahead and change the front wheel bearing as well. Did some research and can't tell if the knuckle needs to be removed also. Can some one shed some light on this for me ?

Thanks in advance
