We tried to disconnect all of ours and put it on the ramp. It made it up another 5 inches (which is a lot), but the transfer case locked up. The issue is the transfer case has clutches in it since its AWD and I think it threw a sensor out of whack and was stuck. After we did it, it felt like the front brakes were stuck and would not come out of 4 lo. Luckily the dealer took care of it, but not sure if he would do it twice. I had to play stupid and swore it happened while I was driving on the road.

The H3 is NOT an AWD system with clutches, it is a full time four wheel drive system. In an AWD system there are clutches that control the slippage between the non main drive wheels and the main drive wheels. In this system, it is in a 40/60 full time four wheel drive operation. The torque to the front wheel is NOT determined by clutches or slippage.
A planetary differential provides the 40/60 torque split front/rear full time, when switched to a LOCK mode, a high/low planetary carrier assembly provides the high and low ranges.
In normal four wheel drive mode, that is unlocked, the input shaft (small shaft under callout 203) is directly connected to a mainshaft (209) by the high/low sleeve (205). The teeth on the sleeve are engaged with the input shaft high speed teeth. The collar is slipped splined to the mainshaft and delivers the power flow to the planetary differential (231) which splits the torque with 40 percent to the front/60 percent to the rear differential gears. (Short version)
There is no set of spin clutches in this transfer case.
Not sure what happened, but you did not have clutches go out of whack, and if the dealer told you so, he has not disassembled this t/case.
Disconnecting the front sway bar should not have set off the driveline angles, so I'm not exactly sure what happened. But please, don't insult the H3 by saying it is an AWD system, it is a full time four wheel drive system, and there is a BIG difference between the two types of systems.

T/case internals...no clutches....
