I am having trouble finding a Dana 44 front axle with 3.54 gears for my `79 Jeep J-20. Is a Dana 44 out of a J-10 about the same except for the lug patterns? Can I switch the hubs around if everything else is the same? J-10's seem to have the right gear ratio.
u can in a pinch use a 1/2T d44 from a j10 in ur j20. the difference is the thickness of the axle tubes and the of the rotors. unless u got a fulltime snow plow or fulltime cab over camper..it shood not be a prob. u might also try GM front 3/4T trucks. they are about the same width as ur j20. the only prob there is that the GMs are set up to have the spring mounted OVER the axle tube, while urs is mounted UNDER the axle tube.. chk out em attachmetn too
