The tcase in neutral still internally has the front and rear outputs tied together, so if one axles tires turns, so will the other...I had mine towed once and it took me a minute to figure out why the front tires were spinning even though trans and tcase were in neutral. If you put it on a tow dolly, you need to either put the tcase in 2wd or have lockout hubs on the front axle...well...or pull the rear driveshaft if the front tires are on the dolly. Trans in neutral of course...
Any time you are towing one of these trucks, I HIGHLY recommend backing off the adjustment on every wheel that has contact with the ground and will be rotating. I flat towed mine and one of the brakes came on...not completely sure why but at least partly due to removing the brake drum screws...long story...dont know if a bump happened or something else but on these self energizing brakes with a single line master cylinder, when one brake shoe catches the drum and comes on, more come on...both fronts on mine did and got so hot the shoes were incinerated and the drums were glowing cherry red. Seals inside the axle were even ruined.
If you loosen the adjustment way way back, then you dont have to worry.
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
