4x4 shift motor

when i switch the transfer case shift motor to high does the shift motor keep it lock in high, and say would a weak shift motor cause it to "pop" in and out of 4wd
just trying to figure how all this works
I'm still having a popping transfer case
I know about tire sizing, not driving on dry payment with 4wd,etc
thanks chad

The mechanical side of the T/C does not come to play in the 2H1 or the 4Hi switch position...

2Hi, drive power straight throu to rear shaft..
4Hi, drive power to rear shaft, with the addition of the front driven via an electromagnetic clutch..
4Lo, the T/C shift a mechanical gear to obtain low ratio in addition to condition in 4Hi.....

If you are experiencing a popping under load, investigate a slack chain.

Hope this helps.... Philip
