need help. ring and pinion separated in pumpkin.

hey guys ,
i have a 98 tj sport running 4 inch suspension lift, 2 inch body . 35x12.5 goodyear duratracs. driving home from work i thought i snapped a shaft . real bad thunk noise everytime the tire made a revolution. drove home in 4wd . just had it towed to my work where i opened the pumpkin (dana 35 rear), it was completely drained of fluid , prior to opening it. and the ring and pinion weren't touching. so i guess the good news is my shafts are fine, but i dont know what could have caused this or ho to fix it. thinking maybe the trans shifted forward. is that even a thing . thanks guys

A Dana 35 isn't strong enough for 35" tires, not even close. And based on that level of damage with even the gear lube having all drained out, my guess is the axle is toast. I'd have a 4x4 shop take a look at it, I doubt the transmission or transfer case had a thing to do with the problem.

And a big welcome to JF, too bad your first post has to be about a serious axle problem.

If properly maintained, 145K is just broken in on the 4.0L eingine!! I have a 98 Sport (not much left of stock sport left) and I have 153k and it's fine. Just maintain it, regular oil changes, and that 4.0 will last for 250k+. I've seen it in TJ, YJ, and XJ...

You search around, you can get an 8.8 and if you have a buddy that welds, you can mock it up and get it done cheap (relatively speaking). Just determine what you want to do, what the ultimate end-goal is, and work towards it. That's what 99% of us Jeep owners do and it's just the means to an end.
