I went and looked at my repair manual and it doesn't show anything specific about the wear you have. But, it looks to me that the pinion is engaging the ring gear too far. I'd want an opinion from an expert though.
I have no idea, that's part of why I bumpped the thread in the Tech Section. There wasn't any apparent metal in the oil.

Yeah I know, it doesn't look familar to any pictures I've seen either. Not what I expected when I pulled the cover. Makes me wonder if I over heated it during break in, or set up too tight. I did have too much gear oil in it for the first 800 miles or so, then I drained the fluid and put the proper amount in (when I realized I had too much), but I just used the drain plug in the T/A cover.
I'd might redo the wear marker paint. Maybe back the pinion depth off. Not sure if you have a new crush sleeve to do it. Maybe just redo the marker paint to see if anything is changed.
Is there any ridging felt on the ring gear?
I'll Hooper's Rearends here. See if I can email those pics to them to see what they think. I'll call them tomorrow.
You weren't having any trouble with it, no noise, no junk in the fluid, no indication anything was wrong? Why do you think you should change anything?
How many miles?
Run a pattern with the paint and post that. Were the gears new or used, I don't remember.
The cover is back on, so no more pictures or trying to run the pattern.
I was playing with the contrast and tint of the images and it appears there is still a pattern there that matches the greased pattern from the set up (you can kind of see it at the top of the first picture). I had the camera set on macro and I'm thinking it just caught more detail than most are used to seeing. The gears were shiny so I took pictures, I first noticed the lines when I loaded the pictures up on the computer. I didn't actually touch it to check for a ridge, what is completely apparent in the picture wasn't too obvious under the car.
It has ~9,000 miles on it. Makes no noise, and as Dave mentions, nor has any other indicator that something may be wrong. So I'm thinking the teeth are polished, just the macro and flash brought out finer detail. I figure worse case I have too little backlash, but I didn't see any metal in the oil.
When we were running the Daytona Prototype I would get new R&P and they would give dimentions where to put each gear. They had fixtures they would run them in and after they were done they would take them out and polish them. I would put them together to their specs. I tried to run a pattern, but it always came out horrible. I would race them anyway and they would last until we lifed them out.
People try to make these out to be some kind of majic, but if you get them close they last forever. anyone with a little confidence and ability can build one.
And I hate used gears. They almost always make noise.....but they still work
To me it's all a confidence thing. The first one I ever did, I looked at it and thought why wouldn't I do this? It was a 9", so that is a lot easier, but the thought process is the same.
Have confidence, even if there's no reason that you should. One of my few rulesof life.

It's all about the small victories. I got the reverse lights working today. Finally got around to hooking up the reverse sensor on the transmission to the wires that were plugged into the column neutral safety switch. Works like a champ now. Also re-installed the glovebox, it's been out since the heater core job.
I put air in the Furys left front tire today...car has not ran or moved since Novemeber...
The only reason I don't work on it are excuses....
At least you're getting something done.

I just commented on your Thread, it is the Small Victories that keep me going. Trust me there are long long periods that I don't do jack to any of my cars. Your problem is your truck is too nice ;) I only own junk :P
