Thanks for the replies... I will check that, OR have my mechanic check it. Is it dangerous to drive this way? I may have to drive the car for about 120 miles for a couple of days (in town driving on Sunday and Tuesday), unless I drive my Lexus, but I may have to lend that to my mother, as her car is in the shop being serviced.
BTW, that wheel is already discolored, so this has either been ongoing, or its happened before.

I do not think its been going on for long though, because this is the first time I have noticed it.
I cannot feel it dragging. It will roll on even the slightest grade on my driveway, because at first I was thinking sticking brakes, so I give it a quick check that way.
Thanks again.
