Need help with t case problems and auto hubs

[halfswede1967]

Hi I recently purchased a 95 explorer xlt. It has a bw4405 transfer case. The 4wd isnt working on it. Tried tapping on the shift motor and got it to turn. Today when i was working on it I noticed when i took the motor off the shaft on the case was pointing to hi. The selector switch is set to 2wd. On the t case where the selector shaft is there is high , neutral, and low. Should the case be at the neutral setting when the selector is turned to 2wd? Also the shift motor only rotates when I switch it to 4L and back. I checked and the shift motor does shift the transfer case into 4L. I did the shift then shut the ignition off and took the motor off to check the position of the shaft. It was pointed to L. Did a check on the ice and still have no power to the front wheels. Back ones spin and the front wheels are not turning. Nothing happens when switching from 2H to 4H with the shift motor. Same thing happens on the ice when in 4H. Next thing is what to do to correct the problem. The other question i have is on the auto hubs. Out of curiousity i jacked up the front wheels one at a time and turned the tires. When I turned them the front shafts coming out of the hubs were turning as well. Is this normal?

Not too familiar with the '95+; they use a different system. Here's what I know:

You don't have hubs like the older ones. The front disconnect is a vacuum actuated thingy in the differential, so the axleshafts will always turn with the wheel.

I'm not sure on the t-case positions. It seems like someone said the shift motor does only shift from 4H to 4L, with the 2H 4auto 4H selection done electronically in the control trac algorithms of the GEM.

Thanks MrShorty.......appreciate the reply and that info should help get me going in the right direction to find the problem. This is my first 4wd vehicle so its all a learning experience for me.

Problem with the transfer case and hubs was due to a chewed off vacuum line. I was having problems with the air changer in the climate system not moving. Well i traced it out to a line under the hood. Looked like it had been chewed off. Repaired that and took care of the air changer and the 4wd system.
