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.
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.
in semifloating axle vehicle carriers all weight of axle where as in fully floating vehicle does not carry any weight on vehicle.

The axle shaft serves two combined function's, it supports the weight of the vehicle and delivers torque to move it.
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.
semi floating axles on E150. Full floating on E250 and E350
It is semi floating rear axel
According to Haynes the 1995 has a hypoid, semi-floating type and some have the optional locking limited-slip axle. The identification and manufacturers codes are stamped on the right rear axle tube on the front side.
A three-quarter floating axle is the same as semi-floating, with one difference. The outer bearing is moved to the outside of the outer end of the axle tube, supporting a hub assembly via the bearing's outer circumference edge. The splined or keyed shaft drives this hub, to which the wheel is attached. The shaft now supports minimal vehicle weight (so has much reduced radial load), but still locates the wheel axially, and transfers axial cornering loads (side thrust) to the axle inner bearing.
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.
