While changing tires, one of the five right front wheel studs broke off. Inspection reveals a faulty void (air bubble) in the center of the stud where it broke off. I have that piece. I bought a new replacement stud and wheel nut from bighorn Toyota in glenwood springs, CO. They will replace it for me in approximately two weeks unless I can find another auto shop that can replace it before then.
