This is a 2008 f250. I was looking @ my wheel yesterday and noticed this loose ring at the hub on my right front . The truck has been pulling a little to the right and this wheel gets noticably hot after driving.

I assume I have a bearing issue? This picture is taken looking forward into the right front wheel well

That's just a dust cover for the axle. Shouldn't hurt a thing. Mine have been loose for over 60k with no ill effects.
