Removing intermediate shaft on trail blazer
Having an issue removing the intermediate shaft in the oil pan. I can't find a bolt with the right threads to thread into the shaft with my slide hammer. I tried a 6mm bolt and I can get about 2 threads in. I tried 1/4 course and it goes in about 1 thread and tried 1/4 fine and it almost seems it'* too big and won't even start. My first thought was that the threads may be messed up on the shaft, but I have a junk yard diff and the diff I'm trying to remove, I think it'* pretty unlikely that both shafts would have bad threads, and they both check out at least visually. Is this a special manufacturing thread or something?? How can I get this shaft out to swap the diffs?
