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!
