I like to use a brass hammer or drift. I prefer to lightly tap the end of the stud or the top of the hub, not the face of the hub...... but obviously some people may say this is the wrong method.
Why did Toyota use a full float?

No idea why, but just my guess. They already pretty much went all out on the NAS 80 Series, so why not add a FF rear a
exactly how I do it. 16oz brass hammer does the job.

That's what I've always done as well. Tap on the stud itself (brass hammer). Have always managed to get them loose that way (cones)
Perhaps because it's ultimately cheaper to stay semi float and just beef up the bearing size and axle shafts to compensate for not being full float.
In general, a FF axle as an option is an upgrade in reliability and carrying capacity. Two big factors in that with the 80 are how many passengers it's set up to legally carry and how much it's rated to tow. Countries have different regs on what suffices to satify local requirements. All that is factored in, along with perceived market position and the competition. For instance, in Australia the 80 was a pretty big tow vehicle, but here people buy pickups, Suburbans and Expeditions first for that. Makes it more likely that a FF would be standard Down Under, but not so much in the US.
IIRC didn't the changeover to the FF in the US market 80 series happen after the extra seats were added to become the 3rd row?

This was my line of thinking too: that the FF allowed them to market a higher tow rating (I.e. it’s not that they advertised the Truck having a FF, rather, they needed to raise capacity/towing at the time due to market competition.
My other theory is that when they switched to ABS, perhaps the FF with its disc brakes, was already available in the parts bin, thus allowing Toyota to quickly implement ABS. But this only holds up if the axle was already produced in the 70 series (haven’t looked up if they share an axle) or another truck.
No 91 and 92 models with semi float axles all came with 3rd row seats in the US. I think the semi float 80 series axle is just a wider version of the 60 series rear axle. I'm guessing when Toyota dropped the 3Fe they must have figured the semi-float didn't have the strength they wanted for the additional power of the 1fz.
