Hey everyone, thought you might like to see how BIG the Tundra diff actually is, so I set one next to an FZJ80 locking 9.5" unit. Spline count for the Tundra is 35, I believe shaft dia. at the spline is 1.41. I have yet to take this one apart to inspect things like bearings. These diffs and the axle are made by the Hino plant in Memphis ,Tennessee. I'll post more info as I have time to get into it... if you have any questions or requests for pics, just ask.
