Sunny - +1 to Kurt. The side-to-side movement (just to be clear, I mean fore and aft relative to the frame, or up and down) you see is normal. There is no support of the axle itself at the outboard end of the axle housing, it sort of flops around out there. Not like a modern car that has a bearing carrier at the outboard end. Once you get the bearing in the hub and the hub on the shaft that should go away. If it doesn't - look for wear on the axle housing, or wear within the hub. The Red Book gives wear tolerances for both, and the suppliers have sleeves to install if either are out of spec.
