Looking to replace my bent 30, found a bare housing, what else am I gonna need to get this thing under my jeep and rolling? I know axle shafts and gears? What els am I missing> will the brakes on my 30 be a direct swap?
What kind of D44 housing is it? If it's from a JK you can swap over the outers intact (knuckles & brakes, etc.). You'll need a differential, axle shafts inner & outer and a ring & pinion. Get some Poly or Dynatrac ball joints, too.
They use the same 32sp outer shafts, so you can re-use everything from the outer shafts outward. You will need new joints to connect the outers to the new 30sp inners, r&p, locker, seals, etc. If you don't want to buy the $1400 factory e-locker, look at a 35sp arb or 35sp ected, along with 35sp shafts.
You could go big with the 35 spline ARB air locker and RCV shafts.
You will need gears R&P, bearings, shims, seals, gear oil... And while you're building it go ahead and truss it and support the inner C's too.
