hey, hey easy now, just trying to figure this out,
so your saying that even if the pavement is covered in ice and snow and no matter how easy you are on the throttle and you still spin the tires in 2wd, 4-hi isn't suitable? also I'm not taking turns tight at all actually very slowly and I still get massive amounts of understeer in 4 hi (yes I'm sure I've put the shifter back into 2wd)
The t-case and diff fluid is honestly the only fluid I haven't checked yet, as far as I know there really isn't any "checking" the t-case fluid ya gotta remove the plugs which can be a pita from what I understand, but if you guys think it's the fluid I'll get out my allen set out tmw, and take a look see and see what I find.
2H, 4H Full Time, and neutral are the only ones suitable for pavement.
Nah. Just get an XJ and drive it like you stole it. You know for sure the PO did stellar maintenance on it, don't you ? The diffs are full of fresh and clean fluid, the trans was just serviced, transfer case is full, engine oil is clean with a quality filter. Go for it!!!!

Both fluid and binding will cause shifting issues.

What kind of tires are you running? Same front and rear? The 4WD system with an NP231 *HAS* to have slip between the front and rear axles to release tension otherwise you end up with mucho binding. Understeer is normal with 4WD engaged because the transfer case turns the front and rear driveshafts at the same speed. When turning the front wheels actually travel further than the rear, but in 4WD you restrain them to moving as much as the rear. This causes understeer. If you're talking about icy/snowy patches on city streets then yes, you should shift back to 2WD as soon as you don't need it anymore. It's not a set-and-forget system like the NP242 with Full Time AWD

I'm using different tires on the front and the rear (yeah I know it's not good but tires are expensive) and Thanks for the incite, you did a amazing job of explaining the issue. I finally got off my lazy *** (it's cold as **** here right now) and changed the fluid, it looked good though when I took off the fill plug none came out so I think that maybe it was a bit low, nonetheless my testing have yet to yield any binding so I think I can call this case closed.
Check the fluid anyway.......
