No, this is not a floating drum assembly on this truck. To remove the drum you have to remove the axle shaft and bearing.
The axle can be removed without pulling the differential cover and pulling any clips from the carrier. In that sense the axle is a floating axle, however the drum is not. All mechanics call them different things, but typically floating means that nothing else has to be removed to remove the part. In other words, if the drum could be removed without pulling the axle then the drum would be "floating". On the other hand nothing additional has to be removed to pull the axle, so it is considered floating.
I have a basic diagram that explains how it's done. Being that this truck is a 1991 not much is published for it anymore.
