Page 432 of the owners manual says "Lubricate the front driveshaft grease fitting at each oil change listed in the appropriate maintenance schedule for your vehicle. Use Mopart type MS-6560 (lithium based grease), or equivalent." Of courge a lithium based grease will work fine, you shoudlbe able to by at Napa, Westbay, or whatever car parts places are in your area.
As for when per the maintenence schedule page 487 you are supposed to do this at 7,500, 15,000, 22,500, 30,000 miles and so on. As for the fitting you need to attach to the zerk it sould be a standard fitting (I just got my truck and have not climbed under to check) that you would have on a regular grease gun that uses a tube stye grease. When you look at the end of the gun there should be a hole big enough to go over the zerk and there are little clamps inside that hold on to it, then just pump in the grease. Normally for greasing a few pumps should work, unless this is the style that lets the grease run out of the joint, in which case grease it until you can see it at the joint, but Im not sure which one it is. A few pumps on the handle should suffice.
Oh ya when you put the grease gun on it the gun should almost click into place, if there is alot of grease comming from the fitting on the gun then it may not be on right, or the wrong one.

It's the same as the 2008 and you will need the needle type fitting to attach to your grease gun.

There is no fitting on 2006 2500 4x4 or 2007 2500 or 3500 4x4 . I mean the rear double joint on the front drive shaft. Its a tiny hole and you need a needle type grease fitting for your gun. If this joint goes bad from lack of lube, you'll have to buy the who drive shaft from dodge and its $520.00 and on National Back Order.

I had a drive shaft made in Houston for mine and it cost $385.00 , thats when we found where to grease it, just a tiny hole. ....It lubes a centering pin and there are needle bearings in it.

Jack one front wheel off the ground and you can turn the drive shaft till you find the grease spot. Good luck.

Can you use synthetic grease for the u-joint? For example, Mobil 1?

Synthetic , yes .... If I have it, I use that, its good stuff. Do the taste test, I do.
The best tasting wheel brg grease is the one to use.

I use wheel bearing grease and I got it at Napa, its a red color. You can get a tube of it most any place, but make sure that its for wheel bearings. Some grease says multi-purpose and if you read on the label, most say for wheel brgs too.

I guarantee you won't see any significant benefit from a $18 tube of Mobil1 synthetic grease vs your standard mltp grease. The hole has a small metal ball that seals the hole. You have to push the needle hard enough to depress the ball so the grease enters the joint. It is in fact a centering pin with about 12 needle bearings. If they dry out they will heat the pin and score it. Once that happens the bearings fall out and the CV joint no longer spins around a centered axis. That is when it comes apart in spectacular fashion. Also, IF it goes, any driveshaft shop should be able to cut the old CV off and weld a new one on and balance it. You really shouldn't have to buy an entire shaft from Dodge, that's just rediculous that they get away with those prices.
Just look inside the joint when you grease it and make sure you actually get grease pushing out around the pin. You will see a steel ball inside the CV about he size of a large marble with a metal pin inserted in one side of it, that is where the grease will come out. I just googled centering pin and here is a link to what it looks like. Figures its a jeep

As was stated earlier, you need a needle fitting. Here's what you're looking for:

Also, you're not greasing the ujoints, so don't expect to see grease coming out of the ujoint. The ujoints are non-greasable sorry to say. Replace with greasables if you ever change them out.

You're greasing the centering ball. Should only take 2-3 pumps. You may see grease come out in the centering ball (between the 2 ujoints).
