At least recently! S-10 Blazer, exhaust system, between cat converter pipe and muffler pipe. They have flanges that bolt together. One of the bolts broke on it"s own - No brainer - replace the bolt. Turns out that"s not that easy. The bolt(s) (broke the second one getting it off.) are harder than heck. Turns out there aren"t even bolts, but studs, kind of like wheel studs. Heads are frozen in the flange. So pound "em out. No luck, even with air impact hammer. So drill "em out, very difficult. Did force a 1/8 inch drill - carbide, with exteme difficulty. About destroyed the drill, had to sharpen it a couple times to drill the half inch or so. Tomorrow, I"ve got to figure out how to enlarge the holes to at least 3/8 inch. And of course, the holes aren"t centered - drill walked something fierce. I don"t have a torch, that"d be too easy. Can"t remove muffler assembly without cutting it up, as it is a one piece unit over the axle. What"s worse I"m working under the car, sitting on the ground. Going to try to get a carbide burr to use on my die grinder. I ground part of the stubs off with a angle grinder, but was slow going. Any other suggestions? (I can"t imagine why those bolts are so hard.)

You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
