I'm trying to figure out lubes for a round of 100k maintenance on my 2011 Durango. Its a Hemi, tow package, 2 speed transfer case and ESC equipped.

The owners manual calls for special lube for the TC: MOPAR NV 247/245 lube. I guess I'll go ahead and get that from the dealer unless there is a good replacement.

For the differentials 3 lubes are listed in the OM: 1) front/rear synthetic 75W140 with friction modifier 2) rear with electronic LSD synthetic 75W90 3) rear without electronic LSD synthetic 75W85

My question is which is it for the differentials? I believe traction control on these uses electronics and brakes/throttle (no clutches) so I don't understand the friction modifier recommendation. I plan to run it for a while and do tow with it from time to time so I want to get it right.

Help appreciated.
