Like all my projects, this started as a drum brake pad check. Now I am wondering if I need a new ring and pinion. Check out these pics and let me know your thoughts. I have never broken into the diff before, so I don't know if this is normal or not. It just doesn't fell right. There is pitting on the ring and grooves on the edges of the worm gears. I plan to do a contact test, but I need to get some marking paint. Any help is appreciated!
