Looking for input on where to start. '72 w/ original drivetrain, lockout hubs. Whent light off roading recently and had to put it in 4 for 1 situation. Unlocked the hubs, and now there's a "tik, tik, tik" sound coming from up front. It's definitely not engine, I shut it off and coasted and the ticking still was there and the speed of the sound is directly related to "coasting" speed. It does go away when I re-lock my hubs. Is there something hanging up in there? Would more serious damage happen if I keep driving it? Thanks up front for the help!
