THERE ARE TWO DIFFERENT TYPES OF AXLES AVAILABLE ON GENERAL MOTORS TRUCKS.
Axle Shaft Components

On full floating axles the drum is part of the hub assembly and they must be removed as an assembly.
Rear Drum Assembly
Semi Floating Axle
On semi-floating axles the drum can be removed without removing the axle shaft.
