Not the hubs nor the Lockrite. I have taking the driveshaft off and tried to spin the flange on the t-case, and it wont move with ease. But if I pound one of the studs, and frees up. Well, it did once, have not tried it again. I aslo know sometimes when I put in park reverse and drive it sometimes free's up, but noticed when acclerating, with locks up. Here is another wierd thing, if the driveshaft spins, and i put my truck on a rock, push the gas, it not fully in 4wd. So it moves is spinning the shaft, but not with lots of force. As if there is some way the t-case is spinning it, but not with lots of force.
Also have taking off the twin stick and remounted, and have tried both Marlin and Front range sticks. The weird thing is, I believe when the driveshaft is spinning, and I pull up to a trail, its very hard to put into 4wd. But once its in, all the compents work fine. Hi/Lo, but once off the trail, unlock hubs, take it out of 4dw, no problem, t-case is free up front. Once I get down the road or stop, put in park and back to drive its locked up again.
