four wheel drive

With some of the Jeep's transfercases while in 4Hi the front wheels will only get power if they are not moving at the same speed as the rears. This allows you to drive on the road in 4Hi without the drive train binding up. In 4Lo they should lock. Some of the older ones don't but by 99 they do. Which is why you generally don't want to drive on pavement in 4Lo. I'm guessing you have a NP247 transfer case. They are usually good for most use.
