14 bolt 9.5" with play

[chevak20]

My Suburban has 400,000 miles on it and the wheel bearings have play. On one side though, I also can slide the wheel in and out 1-2 mm. I have not had time to take it apart yet, but where the bearing sits, is it usual for the shaft to be worn down? Or is it a c-clip problem?

This axle also is in need of a new pinion axle bearing. (Have purchased that already) Been thinking about swapping to a full float 14 bolt. This would be cheaper then a new semi float shaft and bearings where I live. But if so, which one? G30 from a van, would be wider to match the front wheels maybe? Or crew cab axle? I know I have to if so weld new spring attachment points. Or should I go for 4x4 pick up which bolt right on.
