Your car was designed to hold onto the wheels under the most punishing conditions, but it needs all of its wheel studs to do this right. Kind of like trying to throw a football wearing mittens — you can do it but it’s not happening the way it should.If you inspect your own studs and bolts you can avoid a costly repair. If you’re unlucky and find a damaged wheel stud, you can replace it yourself without too much pain.
