Hi Gobrc1
Just found your questions.Doubt very much its a wheel bearing unless it has a lot of play and its making its own noise(usually and rumble).No the bearing is not hard to change I list it as a hub assembly which makes it pretty easy,but a little experiance would help.More then likely the rear of the car is still out of alignment esp if the cupping looks like its at a diagonal angle to the tread.I would get the alignment checked and/or adjusted at a shop that can give you a complete printout of the measurements.If it needs further work it may be a matter for the insurance company if they handled it to begin with.
Good luck,Cadoc
