I thought a ring gear was odd also, and that made me more out of my mind, thanks dealer :rolleyes: I think I lectured them enough in the beggining that they went straight to the diff. Apparently they are used to replacing Titan diffs regularly as well. I have a Titan also, and I have " Tundra" on my mind now.

Rinky, I dont think you can see the spider gears without pulling it out, and the stealer wont do that. They will only replace the entire rear end. But, should be able to learn from the vin if it has 2 whopping spider gears or not during this process sometime?
