Diagnosing Grind Noise in 4L

Hi Jeepforum. I have a 1995 Jeep YJ SOA, 33's, 5spd with 8.8 rear, NP231 w/ SYE.
Recently when I have been doing light rock crawling I have been experiencing intermittent "Grinding" or "Scraping" metal noise whenever I hit a steep incline. The noise has only ever occurred when I am in 4Low and going up a steep incline, never downhill. The noise sounds like grinding gears almost. The jeep seems to remain in 4L just fine when the noise occurs. The noise seems to come from the drivetrain area. Visual inspection revealed nothing and all fluids are ok.
I am curious if anyone else has experienced this before? I am concerned that it could maybe the transfer case chain or something else damaged internally. I have even read that poor adjustment of transfer case linkage may cause similar symptoms. Also note that Jeep drives fine on highway and at all times asides from steep incline. Any knowledge you guys may have would be much appreciated. Cheers -Nic
