I'm trying to get an understanding of front axles. So is a D44 the same from 1/2 ton to 3/4 ton except for 6 lug & 8 lug.(this ones kinda been answered). If they are the same: If a 6 lug & 8 lug both have 4.10's & the 8 lug has messed up gears, which is easier to do: swap the gears or swap the 8 lug axles into the 1/2 ton housing? Here's what I have. I have a perfectly good 1/2 ton 44 & a busted ring & pinion on my 3/4 ton 44 & drum brakes on my 70 1/2 ton. I want to use the good 1/2 ton 44 for the gears in my 3/4 ton & use the disc brakes to convert my 70 over. SO do I use the one axle as a donor or swap the 8 lug axles into it & use the 3/4 ton discs for the conversion?
