I think Andy is spot on...we had a horrendous squeal/rub from what we thought was the right rear...the mobile mechanic came out, jacked up the R rear and pulled the tires...nothing wrong...we drove to his shop, and he pulled ALL the tires off, and the left rear tag axle's spring(1 year old) had broken...he pulled it, and I have driven without tag-axle brakes since then...I asked him to cut the lines...the electric brakes have cost us a lot of time, $$$, and frustration...I think there might be a conversion for tag axles, but I haven't followed it...we cross mountain passes, but drive like the guy I used to be caught behind when I was a teenager in a hurry...road courtesy only exists going downhill...
Also, if it should be a bearing, PARK IT SOMEWHERE CLOSE TO HOME!!! We spent 10 days in Kingsman AZ waiting to get our hub replaced...the Freightliner dealership couldn't find one, so we went online and found 2 in Minnesota, apparently the only 2 left on line in the USA...bought 'em both, and carry the extra under one of Murphy's Laws addendums...
If yer going to have brake work or tire replacement, have them(ok, ok...INSTRUCT them...or DEMAND) that they pull off ALL the tires, and check the brakes and bearings...cheaper than roadside service, and you have documentation...mike
