I wanted to start building up a d30 while I still dd my XJ. Pirate4x4 has the occasional built d30 from a Wrangler.
Mounts and steering aside, are the d30 the same in YJ/TJ's? Width, high pinion, 290X, etc.?
 
YJ's are all high pinion, leaf sprung and have axle disconnects. TJs are all low pinion, but with bolt-in XJ mounts, non-disconnect.
 
Just late model XJ D30s... BTW, width is the same on all, pre-1996(?) axles, except for those with ABS, will all be smaller 260 joints, while newer will have the D44 version.
 
Not sure if you have junkyards in your area, but the ones here are filled with XJs with disco and non-disc d30s. Shouldn't be too hard to track one down. XJs aren't rare :)

How does one know if they have a disco or non disco d30

if you have the big stooopid disco assy on the axle the you have the disco one. if you have a smoothish tube you don't. idk about later ones but early xj's seemed to get the nondisco with the 242.
