Tight nuts

Having run a front-end and alignment shop for a number of years I have seen this all too many times. The aluminum alloy lug nuts interact with the steel studs that they are threaded on to. Not corrosion, but something similar to electrolysis. I don't care how large of an air impact a person use's those lug nuts will usually destroy the threads of the studs. So a torch might be necessary, but that is usually a last resort. The bottom line will be stud replacement, as well as new lug nuts, and a good coating of "Antiseize Compound" will prevent future problems. Yea, it'll cost ya now, but there isn't any other option. Sorry.
