    I have a military rebuilt chev 8 lug Dana 44 w/ 4.56's sitting in a crate in my backyard. I want to swap the 6 lug stuff over since I want to keep my 12 bolt (4.56 gears sitting in the garage). Is there any benefit to keeping the 72-knuckles? It's stored for the winter, so I haven't looked to see if the passenger side is a flat-top knuckle. Does anyone know if it is/should be? Since axle in the crate has all new balljoints, bearings, etc. I was going to just do spindles out, but swapping the knuckles would be just about as easy. Ken Brown on Blazernet posted something about bigger spindles and bearings on post-72 Dana 44's. Does anyone have the year that they went bigger?

    Thanks in advance

    you can do the swap without removing the spindle. you can use everything from the backing plate out. there is a write up (tech section) on going from 6 to 8 lug you can just reverse the steps and it should work for you. you can also searthc the main board.

    Do I use 72 bearings, rotor, etc? or the later, larger ones? If it's a flat top knuckle I'll probably end up swapping it just in case I ever feel the need to do a crossover setup.

    The 72 uses the smaller u-joints but everything is the same...almost. The seal for the axleshaft is a bit different. When I bought new seals the kit (which comes with the spindle bearing, and some seals) had a conversion piece to make the older axleshaft work with the newer seal. AFAIK everything else is the same.

    If I read the 6 to 8 lug conversion article in the tech section correctly, I should be able to use the 3/4 ton spindles only if I use the 1/2 ton stuff from a later-model 44 - anyone know which year the bearings changed? I remember readins somewhere that you can swap the bigger spindles and bearings into the early Dana 44 without a hassle. I'll be using the 'new' axles as well since supposedly all the bearings, u-joints, ball joints, etc had been replaced. Guess I'll have to go visit the Blazer to look at the 72 passenger side knuckle, unless anyone knows if it's flat.
