My truck is stuck in 4WD. I have been noticing for the last 2 weeks a slight vibration when turning corners at slow speeds. My mileage has dropped as well. I attributed that to the Xziliraider I just installed. My mileage has gone from 14. 5-17 to 12-14 towing 4000 pounds. I have noticed it has gotten steadily worse(vibration), so today I gave it a little gas in the dirt, got out and the right front tire had spun. The vibration is worse when I turn to the right. Man, what kind of damage have I done. I have probably put over 1500 miles on it like this. It just never dawned on me that it was in 4WD. The light on the switch is indicating 2WD. I switched to 4 HI and back but no change. I called dealer and told them about it and he said I will be alright. Somehow I dont believe him. This cant be good for it. I already had an appointment for next Friday to replace power steering box, so they will look at it then. Probably an actuator stuck he said. In the meantime I have to work which means another 1000 miles or so until Thursday. What would you do?
