You can jack up the front end and rear end and see if tires are spinning when in 4wd.

if u in 4x4 u sure fell more power when u drive.

It sounds as if everything may be normal with your 4x4 system electrically - you might have a mechanical issue. Your best option is to have a shop put your truck on a lift and look. Give us a call if you would like a second opinion. Rick Steel Prestige Automotive 410-561-9696
