Just a guess here Joe but I would suspect your green light is telling you the Four Wheel Drive is engaged. Check your owners manual for further confirmation.

Sound like the 4WD actuator needs replacement

These details will help.

Thanks.

Most likely U Joints in the front axles. These will only turn in 4 wheel drive.

you have a lever or switch that engages 2wheel normal driving 4 wheel high for wet slippery conditions ,then you have four wheel low for real muddy and deep snow conditions
normally change from 2 wheel to four wheel high on the move .important nearly all 4 wheel drive vehicles must be stopped to engage low otherwise do damage to transmission

The problem may be related to technical service bulletin TSB 03-001-07 which involves replacing the front axle actuator disconnect and a software update. You should be able to Google the TSB and look at the build date listed in the bulletin to determine if it applies to your vehicle.

The clicking sound could be a broken exhaust manifold bolt which causes a exhaust leak that makes a clicking sound. The 4X4 problem could be just a linkage adjustment.
