Well like I said it shouldn't have play at first, you should only hear a noise. The longer you drive on that bearing that is bad it will become lose. I did have a few that had noise for a week or two and were lose but I've also had a couple that werent lose right away. Just took some time driving on it. Note these weren't my cars but customers that didn't have the funds to replace the bearings. Once I hear a bearing noise I replace them as soon as possible. I have found that a bolt-in hub and bearing assy will become lose a lot faster than a press in type.
