Damn! Been over a year since i've done any sorta up to speed with this. Been drivin' it since aug/24, went on a week long backroads crawl/camp where ever tour then. That was also my test run. Had a weird ratchety sound coming from what i thought was a locking hub. Ok, reroute trip plans, took all the trails we'd planned on running out. No sounds with front axle out of the equation. Got home, tore locking hubs apart, no issuses there, clean up, regrease n reinstall. Good trip by the way.
Fast forward to this august past. Week long campin'/ wheelin' up at Ardbeg, that ratchety sound, yup, it's there. 4high, nothing, 4low, on with a vengance, 4low hubs unlocked, nothing.
Finally got a chance to dig into this a little deeper, i dropped the front driveshaft out, put the t-case into 4low n spun the front output by hand, same sound ,all be it much more subdued. To my uneducated mind, i should not be able to spin the output by hand if the t-case n trans are both in gear. Put t-case into 4high n had to use a bar to turn output n of course scoot the truck along. @orangefj45 , i trust you might be able shed some light on this for me, is this a linkage not functioning correct problem, i.e.not getting all the way into low. Possible gear issue? I'll be honest, i can't follow the flow of power when looking at exploded t-case in the fsm so that's got me puzzled.
Another bit of info that may or may not help, just for $h!ts n grins i drained off a bit of gear oil from said t-case looking for metal glitter, nothing showed n rare earth magnet picked up nada
