Hey everyone, been lurking on here for a long time but have finally made the first step of my end goal. About a month ago I bought a 1988 FJ62 from a member on here, Orion, and I couldn't be happier with it. I've done a few cosmetic things to it but nothing major as of yet but I am looking to address a mechanical issue. I was informed when I bought it about the issue and was fine with it but would like to try and pinpoint it and fix the problem. It seems that there is excessive noise from the transfer case. It isn't grinding but is more of a whirring/droning noise. I can feel the noise through the T-Case shifter and from reading other threads I have found other people have had the same issues. It seems to get louder the faster I am going and still remains when I let off the gas to slow down unless I just barely depress the gas pedal. 4wd engages fine and doesn't seem to make any unusual noise from the little bit I have had it engaged. I was hoping to possibly get some help or a list of things I could check or cross off the list to come to a solution on how to fix the problem. Picture for attention. Thanks
