    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!

    What does not feel right? Do you know the backlash?

    Going on the pictures, I'd check for cleanliness, lube them up good; and run them.

    I dont think it's terrible. There was obviously water in it for some time in its past life.

    If it doesn't scream when driving it leave it.

    However id pull the axles and then the carrier to inspect all the bearings for pitting.

    Damn you guys are fast! It's not causing me noise or issues. I pulled the axles to change the bearings (SET10 and 9211 seal) and decided to change the gear oil while the whole thing was apart. That is when I saw the pitting. The backlash is .012, which I think is out of spec but I need to check it again. I like the advice to pull the carrier to look at the bearings while I in here.

    If it doesn't make noise and it doesn't get hot, I would not worry

    No, .012" is good, real good for a used set. No noise, no chunks, no heat is all good.

    Thanks gents...never seen a thread where everyone agrees! Time to clean everything up and slap it back together.

    If that ring and pinion came thru my shop I would change it as I would not be able to stand behind a gear set that looked like that. Besides the rust it does have a funky pattern to it. Since you're not rebuilding, and were merely just servicing it, I'll agree with the others and just run it until it wears itself out.
