Hey Draenor,
Unfortunately, I got myself into a pickle on this one. I was looking for someone locally to rebuild mine but didn't find anyone. Knowing what I know now, $1100 would be reasonable to get it rebuilt.
I ended up locating a used one for $1050 shipped, so I went that route. The used one has all the options my current one has except the locking diff. I'll just have to live without that desirable feature......
If I had a little more time, I think I would have found someone within a few hours drive and had it rebuilt. I would have been more comfortable taking that route, but my lack of knowledge on local repair shops and the need to get my truck running ASAP forced me to go the used route.
The local dealer told me the ring gear and pinion was going to cost me $800. I know I could have found them cheaper, but didn't take the time to research that.
I think this is going to be one of those expensive lessons you learn in life. The next time I hear a roar coming from somewhere in the rear of the truck, I'll see if I can open the diff and take a look. I've always gone with the strategy of "If you can't find the problem, drive it until it breaks". That was the wrong decision this time.
