studs look ok Zippy, but the threads on the nuts are, well, none existent. Lucky the studs are made from much stronger metal than the bolts, so most likely this has been caused by an unfriendly impact wrench. I have been able to fit and tighten some spare nuts in place, so HOPEFULLY these spare nuts havent made things worse!
I wont PM Adz as he has left the club I believe, and I will check the scrappies when I can. Are the wheel nuts generic? Can I get some from anywhere?
