What is everyone running and what is a good combination right now I have the d30 front a Chrysler 8.25 rear and a np231 t case Is there any week links or is it good enough for dd and weekend wheeling

You're set with a proven time and time again set up. Unless you're trying to do some extreme crawling/ wheeling you'll be ready for some DD and part time fun.

What size tires are you running? With my 235/75-15 tires, my D30 and D35 are holding up fine, and I wheel my Jeep hard. Once I bolt the 33's I have on it, I'll start worrying about the axles, mostly the D35 rear. I wouldn't worry much then if I had the 8.25 though.
The NP231 is by far the best transfer case Jeep put in the XJ, I wouldn't worry about it at all. I'd only swap transfer cases if I had the 242.

What or how do I fix so the t case stopes jumping out of 4L and it's all factory tire size and lift only mod is no sway bars and cut finders

I have a d35 in my rig its fixing to get swapped out for a 8.8 with 4.10 gears then the 33s go on! I have 30x9.50 right now with 3.55 gears.

Your good now but once you lift it higher or bigger tires you need upgrades then.

Does the xj come factory with 3.55 because I have the diff tags that say 3.73

kirknd4spd

They could have a few ratios. 3.07, 3.55, 3.73, 4.10, and 4.56. The most common ratios seem to be 3.07 (4.0 5 speed), 3.55 (4.0 auto), and 4.10 (2.5 5 speed).

On both front and rear? I would say you have the "semi rare" towing package

I have a 4.0 5 speed with d30 front and c8.25 rear the rear tag has been misplaced maybe a rock took it but its gone so I have no clue rear gear ratio

stang65

if its stock its 3:07

stang65

should be 3.07

If been looking at the jeep a little more I bout it thinking the t case drive chain was stretched and jumped links. Come to find out im running two different gear ratios my d30 front has 3.73 and my c8.25 has 3.07 why are they different and what is a good gear if I regear
