Half shaft treatment...

I was told by someone knowlegeable about these things to check the halfshaft splines when re-assembling the diff. Cose inspection shows slight ridges worn into them. Using some emery paper I smoothed these ridges down carfully, at both ends of the spline. The theory is that if you leave them on they create a potental fracture point, as the points of wear are slightly different when you put a shaft back in.

I don't want to seperate the diff again...
