Been discussed a lot in the past. Seems like the consensus from the experts is that there isn't much difference between these Moly fortified greases to matter for the average user. If someone's driving across the Arctic they might want to use a NLGI #0-00-000 grease (more liquid viscosity) or if they're driving in water constantly maybe a Marine grease would be better.
But for 99% of us, just about any grease that meets the minimum specs should be OK.
IMHO it seems like if Toyota engineers saw that their solid front axle designs (which are still being produced in the 70 series) needed a grease with different or more detailed specifications they would state that in the Factory Service Manual. Or, if they were seeing early unexpected failures I assume they would issue a TSB (Technical Service Bulletin), at least for current/recent production 70 series.
But we know from our collective experiences that the factory CV joints (Birfs), wheel bearings, spindle bushing/bearings, U-joints, and slip yolks last a very long time before they need to be replaced, assuming they were properly serviced and not run dry or run with contaminated grease.
The experts (I'm not one of them) seem to agree: use what grease you got or what you can get, keep it topped up (with a compatible grease base type), service components as recommeneded in the FSM, and pull everything apart to clean and repack if the grease in the knuckles, hubs, or bearings gets contaminated. FWIW.
