mark, i wheeled a d44 front with 40s for 5 years, i broke several times every weekend until i started running the following setup

warn premium hubs with upgraded bolts, and cryoed internals
alloy USA axle shafts with 297x u joints tack welded on, use bushing internals rather then roller bearing u joints
i had an ARB with 5.38s

this held up well with triple cases, 200 horse motor, and 39.5 boggers

arb also makes a locker for the 44 that makes it possible to run stock dana 60 axle shafts in the 44. i sold the rig before doing this


i know that chevy and ford 44s have interchangable knuckles.
i know that you have the skills to get GM "big hub" 44 8 lug knuckles on there. they have dana 60 size wheel bearings and larger brakes

this was the rig in question
