The drive axles are the rear axles which have or can have power directed to them. On 6x4 truck (common to North America, southern Africa, Australia, etc), power is distributed evenly between the two axles by the power divider... i.e., both axles are continually driving the truck. Some trucks are set up in a 6x2 configuration, where there is only one drive axle, and the other axle is a dead axle (often one that can be lifted). This configuration is much more common in Europe than in North America.
The axle on the driver side of the vehicle.
#1 axle is the steer axle, #2 axle is the front drive axle, #3 axle is the rear drive axle.

The power unit has a steer axle, and only one drive axle.
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.

From the center of steer axle to center of rear axle on trailer. If you want just the truck it's the center of steer axle to center of rear drive axle.
All axles have brakes on them.
This would be axle grease. It is usually a thick, semi-solid grease made from petroleum.
