I just pulled the cover off my Dana and found some pitting out on the edge of the teeth. I'm thinking I was lucky as they were about to start breaking off, but thought it was interesting how they were starting to fail. Looks like there may have been too much stress put on the outside edge.
Any ideas?

Another question, has anyone used one of these Ultimate covers and do you have to machine the caps for the supports in the covers to work?
