I've never had so much trouble with wheel studs as I am having with my Forester! Removing the wheel, I break free the nut, but after a couple of turns, the nut freezes up and I end up breaking off the stud. This has happened to four studs on both rear wheels. Fortunately, I was at home at the time … scary to think of this happening on the road during a tire change. At first, I thought it was due to the tire shop when they put new tires on the car, but this freeze-up happened to a stud I had previously tightened by hand. Is there something unique to Subaru's tire studs that require special handling, or is this a quality, or engineering problem? Has anyone else had this problem?
