When I was checking the ball joints today I noticed that the right front wheel makes a little bit of noise when turning it, it does not seem to be loose at all. I was wondering could it be the wheel bearing starting to go, even though it is still tight? And if it is should I go ahead and replace it or run it for a while until it gets a little loose? I know that when I replaced my left one it had a lot of slop in it. This is the original bearing and it does have 290,000 miles on it, so I can understand if it is getting tired.
