You guys rock!

Dean I never realized you worked on the diffs, but it does have a little side to side and up and down play, when I turn the yoke clockwise, and take the slack out of it. Im thinking at most 1/8" side to side, up and down, and maybe not even that much in and out.

When I turn the yoke counter clockwise and "tighten" the slack up, there is no play at all.
The rear axle drive pinion seal seems to be sloppy in the housing as well, but there is no signs of leaking at all.

Roland thank you so much for the diagram, very much appreciate it.
