I really didnt see any gains maybe a 1/2 mpg increase at most but then again I have 40s and 3.55 gears.

"The Ram Man" has a new conversion kit. Looks pretty simple, but wanted to see if any of you guys have experience with it.

It still uses a sealed bearing. For a bit more Dynatrac and others offer two tapered serviceable bearings and a much stronger 35 spline axle shaft.

Real world mileage? In all my years (starting in the early 70's) driving 4X4's of different kinds, I have never seen any difference in fuel mileage front end engaged or disengaged. Weather it be hubs or CAD, no difference. A long time ago I just started leaving my front axle engaged. It cut down on wear and tear on the CV joint, drive shaft, and the differential in general.

Yeah, I noticed he didn't mention the spline shaft, whether a 30 or 35, and I did not know it was a sealed bearing. He claims you can grease them through a grease fitting, so what gives?

I talk to a local guy regularly about our trucks, he has the dynatrac. Says maybe a mile or two..but his truck has almost 200K on it and various other goodies.

He noted steering feel as the best benefit, says it steers a lot easier without hubs locked in....
