2016 CTD 2500 REAR DIFFERENTIAL QUESTION
I was looking at the window sticker from my 2016 CTD and I noticed it said I had the optional "Anti-Spin Differential Rear Axle". Ratio is 3.42. Does that mean I need to run the friction modifier in...

I installed the aluminum Mopar cover on mine. ....pulled the axles and hubs and drained the fluid trapped in the hubs, cleaned and repacked the bearings in synthetic moly grease and put it all back together.
Never heard of packing outer axle bearings with grease. When servicing hubs I have either dipped the bearings in oil or lighted coated with grease during install, but that was just to be sure there was lube on them until the gear oil got out there. When running normal there should always be gear oil running over the outer bearings.
I had issues where my hub seals were leaking. I finally found a source for unitized oil seals and installed those and haven't had a problem since.
I do some heavy hauling on occassion and wanted better cooling for the axle. I found a good deal on an AAM aluminum finned diff cover and installed that when I put in the unitized seals. I haven't used a temp gun so I can't give a before and after comparison, but I feel a lot better with the extra cooling abilities.
