Just replaced my stub shaft right side 2011 Ram 4x4 it was a lil overwhelming to think of but quite simple to do, and I didnt remove the CV axle nut like the video showed, I didnt see any threads on this so I 5wfigured I'd start one,here's link to video which is quite informative. Parts from Rock Auto $115 shipped... I used 75w140 lube with additive to top off diff..video is for seal but the axle is right there and slides and/or pops out

 

didn't think the front diff needed limited slip additive

 

It doesn't. I think the only traction adding device offered in the front axles from the factory, is an electric locker in a couple models. (Power wagon.....)
