corporate 10 bolt front differential

[bluejean]

I have a 1984 chevy 4x4 k20 diesel with a corporate 10 bolt front differential that i'm trying to rebuild. I just wanted to replace the bearings. It's funny how they don't have any shims. The carrier has thick washer on both sides. The pinion has a oil slinger or you can say shim behind the larger bearing. As I try to assemble the pinion back into the case and trying to tighten it, I don't feel the crush collar pre load. What I have is some play. I going to re seat the race. Has this ever happened to anyone? http://67-72chevytrucks.com/vboard/a...1&d=1344738013
