32? spline is referring to the spline count where the axle engages the differential. Stock Broncos are 28 spline, F150s & 78/79 Broncos are 31 spline. Not sure about 32 spine, but more splines are better/stronger.
Full floating axles are used on F250s & F350s, they carry the weight of the truck on a different part of the axle, it is stronger/better. Maybe why its 32 spline, not 31 spine. But maybe the guy is mistaken too. Not many full floating 9" axles, but it would be a very strong axle, for sure.
The Detroit Locker in the rear axle is a very strong locker. I had one for about 15 years in a daily driver. They are somewhat unforgiving, but not undriveable. They will chirp the inside tire around a tight right hand turn, and can be exciting in the snow.
Its a strong trail rig, not a Costco Cruiser.
