Taking one of the nuts off, the stud broke.
I welded a nut to the end of the stud so I could get a socket on it, but she doesn't want to turn. Feels like it will break again. So I've been hitting the stud with PB Blaster. I could heat it with a torch. Hopefully it will come loose, but I may end up having to drill the thing out and tap the hole for a step stud. Grr, right before WCR (IMG:style_emoticons/default/headbang.gif) Any suggestions? |

Visuals, see pic below...
Left: The broken stud with the flatbar welded to it. Yeah, crude, but I got it out. Middle: The stripped stud that started this whole mess. Note the galled threads at the head end (bottom), full of aluminum from the head. I'll be drilling and tapping that hole for a larger step stud. Right: A new step stud. Only problem is, this is the longest one my local VW shop had, and it is shorter than I want. I'm hoping I can find a couple of longer step studs locally tomorrow so I can fix this thing on my lunch break and drive it to WCR. Attached image(s) |

I think the OD is about 10mm (maybe 12). You drill and tap the head. The difference is it is held in place by 4 small keys that are stamped between the od of the threaded insert and the tapped hole. This prevents removal. I did need to modify the tap used to allow the threaded hole to tapped deeper. A step stud was not necessary. These are available in stainless steel. |
