I've got a noise coming from driver side front. It doesn't match the rotation of the tire. Since there aren't any lockouts on this truck and its constantly engaged, will the drive shaft to the from end turn at a much slower rate then the wheel?

 

It was the driverside bearing. Let loose two days ago. It had five bearings left in it by the time I got home. Made it much easier to get the hub out...lol.
