Floating 8.75 axles

Can someone explain what you are all referring to? "To me" floating axles are such as found on 3/T and larger trucks (normally) and early WWII Jeeps. This is the kind where you can pull the axle out and the wheel/ drum/ hub will still be "functional" on the vehicle

Same concepi as large trucks. Instead of the wheel end of the axle being bolted it has splines on the end and corresponding splines in the I.D. of the hub. There is a cap on the end of the hub that captures the axle inside where it "floats" between the cap and pin in a sure grip type rear end with about an 1/8" clearance.
