OK so these are not planetary but spider gears like in the diff. Could planetary be installed in place of this whole setup? Why not?

The axles are a bevel gear reduction on the wheel end, not portals. Regardless of bevel gear size the reduction will always be 2:1 unless they are eliminated.does the FMTV have portal axles? Can you change the gears in the hub? I can have gears made pretty cheap.
Hi, sorry that is not always true. The ratio is that of the drive gear and the fixed gear. So the axle drives a bevel gear and there is a fixed gear on the axle housing with spider gears fixed to the hub. If the 2 gears involved are both 24 tooth like I think, it will be 2:1 reduction and turn in the same direction. I have heard other ratios but since I have not seen and counted myself I reserve comment. Further research is needed if increasing the drive gear by 1 tooth and reducing the fixed gear by 1 would be enough or maybe 2 is needed. Many things can be done, nothing is impossible.The axles are a bevel gear reduction on the wheel end, not portals.

Agree. The 2:1 ratio is that of 'diameter' to 'radius' and is constant. The actual diameter does not matter, nor does number of teeth. The teeth simply couple the "spider" gears to the end plates, allow them to transfer torque, and could be any size.The axles are a bevel gear reduction on the wheel end, not portals.

I should have added IMHO preceding my comments. I have been wrong before.Agree. The 2:1 ratio is that of 'diameter' to 'radius' and is constant.
