So I am going to swapping out my Dana 30 for a narrowed J10 Dana 44 that has 27 spline outter shafts, getting a pretty good deal on it so I am stoked. I know it is common for people to opt to use the 27 outter stub shafts, outter knuckles, spindles, hubs, rotors, ect ect to get the desired 5on 5.5 bolt pattern. So if this axle has the 27 spline outter stub shafts it is safe to assume that this J10 D44 has the Dana 30 stuff on it? Another Question, if I buy this axle I would like to go back to the larger Dana 44 outter shafts, so what parts would I need to dig for at a junk yard in order to use outter dana 44 parts, and have disk brakes and a 5x5.5 bolt pattern. I have read a lot of stuff about putting Dana 30 stuff of a Dana 44, BUT I am having trouble finding how to go back to using the Dana 44 outter parts. Thanks in advance folks. Also if you have any other insight as to why maybe keeping the Dana 30 stuff on is good, just let me know why.
