Bad transfer case
I've been having an issue with 4th gear, and sometimes third. In the higher gears I'll be driving in overdrive and it will start making a grinding sound, then downshift. It did it a few times, and today I finally figured it out. I put it in reverse today and nothing but grind. I put it in drive and it went into gear perfectly, hit reverse again and nothing but grinding, and it wouldn't move. A buddy I was talking to slid under the jeep and said he could see the yoke for the front driveline rattling around. I put it into 4lo, and reverse worked perfect.
I figure it's either a bad chain or a bad planetary. I'll be throwing my spare on tomorrow. This makes 2 bad transfer cases to go with the 2 zj's I've owned. Are the stock transfer cases in the first gen zj's that bad? Or am I just getting lucky? I plan on swaping in a 242 anyway, so this probably just means I will be ruining a junk tc for the input shaft instead of my spare.
I should probably add, It's a 94 gc, and I just put a used, but vetted tranny in it and I put a quart and a half in the tc 120 miles ago, when I reinstalled it. I dont know if it was low before because I didn't check, but I lost enough fluid between removing it and turning it around cleaning it to be sure I needed to top it off before driving with it.

If it's the NP249 that has full time, neutral and 4 low, they aren't that good of a transfer case. Swapping to an np242 is a good idea.

Mine did good then, it's almost to 200k. I should probably get off my lazy butt and go change it. Being layed off between jobsites sucks. You get lazy if you don't make yourself go do stuff.
