In a full-floating axle, the axle bearing is placed on the outside of the axle housing. This places all the vehicle weight on the axle housing and none on the axle itself. This is important for the front axle which is generally a short shaft. In the semi-floating axle, the axle bearing is placed in the axle housing and the axle carries some of the load of the vehicle. The main advantage of the semi-floating is that it is simpler (i.e. cheaper). Courtesey of: http://www.m38a1.ca/axles.html Sourced by: Paul Henderson, Donegal, Ireland.
Dana full floating
in semifloating axle vehicle carriers all weight of axle where as in fully floating vehicle does not carry any weight on vehicle.
Front: Dana model 44 full-floating solid axle. Multi-leaf special springs. Standard axle ratio 2.73:1 Rear: AMC semi-floating solid axle. Multi-leaf special springs. Standard axle ratio 2.73:1

A semi-floater axle is one that all the vehicals weight and rotational torque are placed on the outside bearing and axle. A full-floater axle has a separate bearing assembly on the end of the axle housing to support the weight of the vehical and rotational torque is the only load on the axle shaft. A full floating axle is easy to spot because the bearings protrude through the center of the wheel.
the only difference to changing brakes with a full floating axle , is that you dont have to remove the axle the brake drum will come off the hub with out removing the axle. you may have to get underneath and back off the brakes to free it up enuff to move the drum

they are oil bath, they get oil from the differential
Depending on the market and the model, full floating rear axles started appearing about 1976 - in the 45 series and others. Most rear axles in North America were semi-floating until about 1992, when the 80 series all came with full floating axles and rear disc brakes. There are far too many market and axle possibilities to make a blanket statement about what may or may not have been equipped with full floating axles and when.
1. Lighter in weight 2. Economy of parts 3. Less expense to manufacture
depending uopn the year you can do this but be sure to match your gear ratio to the front differential or better yet replace as a set.
