I have been reading the "tearing into the rear end" thread with great interest. I am thinking about opening up my rear axle again this winter to see how my rebuild is fairing. But first, is there a spec for axle freeplay if one wheel is rotated while the other is held stationary? That is to say, if one rear wheel is lifted off the ground, how much back and forth rotation should there be when you twist it, as measured in degrees of rotation or actual travel at the tire tread? Also, if everything is new and the pinion is properly located, what would affect this freeplay? A shim behind the ring gear?
Trust me, I am not looking for a major project here, and if my rear is in spec I will leave it alone. It runs quietly and the Rux shifts well.

William - surely there is something else on a T to worry about, isn't there? I am apparently not as curious a person as you
Simply put...A lot.
Turning with one wheel up, you have the tolerance of each component that moves showing up there.
E.g. Backlash, spider gear and Ruckstell components.
Even modern axles have a lot of play like this.
