Pros 2wd option is great. Definitely better than the original 249 I pulled out.
Cons D30 is not open diff, so I haven't noticed a vast improvement on gas mileage.
Recommended yes

Comments: The viscous coupler had gone out (no surprise at 166k miles) and the chain had stretched out, so I decided to just swap in a "new" 242 case out of an XJ. I swapped the input shafts and put new seals in it and it's been working well for me since. I think I need to install a t-case drop kit though, since i noticed my rear drive shaft sits a little shorter in the cone than before. This is causing a little bit of hopping on dry pavement in 4wd, but it's no big deal because I mostly just run in 2wd. I have to get new tires again now too, since the old t-case chewed up the front passenger tire really bad and now it's bald.
