I really appreciate all the inputs, thanks folks. I believe I have the DISC that can be turned. Bad pic I know, had to travel today and took a quick shot. The machine shop said $50.00 to turn, but from what you guys are saying is don't waste the time and money. The machinist did say he would have to mic it first. Quite honestly I am a little disappointed the DISC is giving me trouble, especially at 8K miles. Again, thanks for taking the time to share your advice.
