The Liberty is available with either a part-time Command-Trac or full-time Selec-Trac transfer case.

which system ? its and option new, and we can not guess that.

part time? or full time. 4wd.
driving on what road, pavement, ice, snow, offroad, gravel roads. what?

same question posted again. already answered.

bad tranny
check fuses
check tranny level using the operators guide instructions do not guess
do not over fill a tranny

This sounds like you have a bad tire

it can either a bad wheel bearing or there is no fluid in the fron diff.check the gear oil level in the front diff. and the other is jack it up and see if there is play in either front tires

did he try backing it up?....sometimes they stick in 4 wheel if on dry roads

if you are driving on hard surface ( sealed roads) in 4wd then don't as if damages the drive train
what is happening is that there is a torque wind up from the front and rear wheels running at different distances and the cluck you hear is when at some point that torque is released and allows the selection to disengage or engage
4wd is for use in slipper conditions unless you have an AWD which will become 4WD when required by you after selection of the control

dealer only ,newer model ,this vehicle uses encrypted software to make work that only the dealers can do

sound to like yu seized the engine, sorry
