Background - 2001 XJ auto with the NP 231. Just completed an SYE install and at the same time replaced the transfer case chain. Took my front DS and moved it to the rear so I could drive it, then went to the JY to get a new DS for the front. I do know that it will need new u-joints soon, but is fine for now. I average about 250 miles a month, and just locally - no interstate runs further than about 3 miles.
Took it out yesterday to put it in 4L and drove around in circles to make sure things were working as they should. Seemed ok, but when I went back into 2wd I got a clunk when I started to accelerate. Went back into the grass and drove a few more circles and it went back into 2wd fine that time.
Today in the garage, I fired it up, put transmission into N to shift into 4H and 4L in order to fix the dash lights. I had swapped bulbs so I shifted to see if they would illuminate. Anyway, while the transmission was in N, I shifted from 4L into N then into 4H on the t-case and going into 4H, there was some major grinding as I shifted into 4H. Noticed that if I went really slow I could make it grind continuously. When I "slammed" it from N to 4H it grinded just as if I had to make a gear that was still mesh into a gear that was rotating.
Never noticed that kind of gear mesh grinding before I did the SYE install. Any ideas?
