Well, that was 9 hours of my life I will never get back. Pulled the Truetrac out today so I could separate the ring gear and try to get the snapped bolt out of the ring gear. Disassembly was the easy part, drilling out the broken off piece of a Grade 8 bolt, and then tapping a hardened ring gear not so much easy. I have to admit the whole process would have gone smoother if I had centered the hole I drilled into the Grade 8 bolt, and if I had spent a little more money on a better drill bit. The extractor set (easy out) that I bought at Home Depot laughed at me an the threads stripped before catching. Back together now with all 10 ring gear bolts and a 20 mile drive...all is well again.
