My technical guide is an alldatadiy.com subscription. It describes 10-1/2" and 11" ring gear full floating axles. I have a 14-bolt, v-bottom LSD with 3.73 gears. Does that identify which rear axle I have? Most diagrams suggest 10-1/2" but it's not absolute.

alldatadiy says to remove the axle then remove the hub. It describes a nut that requires a special tool. Does the nut hold the hub to the axle housing or does it only set bearing preload?

If the nut doesn't attach to the axle housing, what keeps the floating axle, wheel and all attached to the housing?

Thanks,
Sixto
