Yep, as some of you mentioned, when in 4WD low, the vehicle moves in a much different fashion. Because I didn't like that, I decided to remove the front driveshaft since I rarely used 4WD anyway. Anyhow, I later changed my mind and reinstalled the front drive shaft, deciding to live with it when maneuvering at a campsite. That RAM was a good truck, quite a hauler. The one thing I didn't like was the diesel particulate filter system. Anyhow, she did run very well even though there were times I needed to allow the truck to burn off the particulates in the DPF at times. I found I could do that by driving around town for a short while in a lower gear to keep the RPM's up.
