A "full-floating axle" is used for heavy-duty load conditions. The axle is not attached to the wheel hub. In fact, it is possible to remove the axle while the wheel is still attached to the differential axle tubes. The axle housing carries the entire load of the vehicle, leaving the fully floating axle to only deal with the engine torque. By separating the two functions, the rear axle can effectively carry more load and transfer more torque than a semi-floating axle. A full-floating axle is commonly used in heavy-duty 3/4-ton and 1-ton trucks, providing a more even weight distribution over the axle than a semifloating design.
