When I got my car inspected( PA state inspection) in Jan 2005 the garage put the front wheel on to tight( a local firestone). Now this morning I wanted to have snow tires put on and the mechanic could not get on of the lug bolts out. He said that he was afraid to break it.

Question is if you do break the bolt what is involved in replacing the hub?
This car is a 95 e320 wagon.

Thanks
Alan
