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...

Correct (nominal) level is one-quarter inch below the hole, plus or minus one-quarter inch. That means a range from the bottom of the hole to a half inch below it.

Yeah, I saw that on youtube. One guy made a little L-shaped tool to put in the hole and measure the height. But I also read, "one-quarter inch below the hole, plus or minus one-quarter inch" to mean even with the hole is OK.
Yes, I guess I was just restating it in the way Dodge and AAM did. If you want perfection, go for the quarter inch low.
I installed the aluminum Mopar cover on mine. I had fallen for the more is better hype and installed a Mag Hi Tech cover and raised the fluid level to their recommended level and then later Gayle Banks came out with his series of videos last fall on rear end covers, and I pulled the cover off, installed the Mopar cover, and 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. There was no grease left in the bearings, it had all been washed out. A lot of folks will tell you there is supposed to be fluid in the hub, but that is not how it is designed. The owners manual even says to repack the bearings when the rotors are replaced. A rather odd recommendation vs a simple calendar or mileage recommendation.
I think the fluid is recommended to be changed rather frequently when used for towing or heavy hauling.
