Rear wheel is wobbling!

I noticed today the rear outside brake caliper is rubbing the rotor so I removed the rear drivers wheel to check it out and noticed the entire wheel hub is moving (wobbling) around! There are no loose nuts or bolts either. Not sure if the bearings, CV joints or what is shot. Never serviced anything on the rear suspension and w/ 193k miles I am sure something is plain wore out. It wobbles so bad that it looks like the entire rear wheel and hub could fly off! I studied how the half shafts and the rear hub interconnect and I just cannot figure out what this could be. Any suggestions would be appreciated!

Wheel bearing! Not a hard job. You just need to pull of the rear knuckle and get a new bearing pressed in. Should be like $40 for the bearing and $20-30 to get it pressed in.

I have seen those halfshaft nuts back off and cause a loose wheel. We used to see these from time to time back when I started working at the shop many years ago. I suppose tightening it back down pushes the bearing back together. If you can move the hub itself around and the knuckle is not moving while you do it, it is probably the wheel bearings.

Ok, guess I may tackle this fix before the rear wheel falls off completely while driving. Any tips of suggestions on replacing the rear wheel bearing? Anyone know what size tools are needed for this job? Will an alignment be needed one repair is complete?

Thanks for any input!

If the nuts are loose, chances are the bearing is toast - the nuts are not supposed to be re-useable either. They need to be torqued to 250 Ft lbs .. and you will need a 36mm socket. As for the hub bearing, you will need a 12 or 20 ton press or take it to a shop with one .. just make sure the bearing is supported properly ( like with an old bearing ) when you press it in. And inspect the Hub itself for any damage, often when I find a bad bearing, the hub gets chewed up as well - especially if it has been driven on while loose.
