They all use the US made 8.25, a CRD would eat a D30.
Yeah the WJ got 30s but it has full time 4x4 to make the driveline's life easier with the 2.7 CRD, the KJ only had selectable 4x4 and the CRD has too much torque for a small Dana, all the exports got 8.25 and a lot were LSD, if I boot mine it will spin the rears when I'm hurrying out of a junction, especially if it's towing.The D30 is in the front.
Jeep Dana 35 and 44 commonly use a pressed-on bearing and no c-clips. I know of other examples where 'foreign' models got alternative axles. Not sure about the Liberty.
I have a spare D44 rear from a WJ. Many of them used the 242 select-trac tcase like the KJ.Yeah the WJ got 30s but it has full time 4x4 to make the driveline's life easier with the 2.7 CRD, the KJ only had selectable 4x4 and the CRD has too much torque for a small Dana, all the exports got 8.25 and a lot were LSD, if I boot mine it will spin the rears when I'm hurrying out of a junction, especially if it's towing.
From what I've read the later 8.25 is similar strength to a D44.
