I have 89,000 miles on it... I will have the tires rotated to see if the noise goes to a different spot...

So if I have to replace the bearing, all I have to do is take off the caliper and the rotor, loosen the small bolt on the clamp, and then take off the clamp nut... pull off the bearing, and put on the new bearing, tighten the clamp nut, and then tighten the small bolt?

Any special thing to look out for?

Oh, how hard is it to pull the old hub bearing out?
If I don't have a puller, can I put the wheel on and whiggle it off?

Thanks for you help
