Default Anti-Spin Differential in rear only - friction modifier question + Helpfull info for everyone

Im changing the oil in my differentials and just need some info confirmed. This is what I've been able to come up with... I hope this info can clear up questions for anyone looking to take on this project and confirm my findings at the same time.

Rear diff - I have the dodge "anti-spin differential", which is an LSD. I plan on using Amsoil 75-w140 with Amsoil friction modifier. The Differential capacity is 2.45 Qts. The friction modifier is 4 oz. So Ill do 4 oz. less of the gear oil to make room for the friction modifier so Im putting a total of 2.45 qts. of fluid into the diff.

Front - Is a locked differential and only used when the truck is shifted into 4WD so no friction modifier is needed. It requires 2.38 Qts. of 75 w90.

Transfer Case - I am also changing the oil in the transfer case. It requires 1.7 Qts. of ATF.

I Chose Amsoil products after a lot of research. RP, Redline, and Mobile 1 are also great products you cant go wrong with. Im partial to Amsoil though. I already changed the trans fluid out to Amsoil so I figure Ill do the rest of the truck.

If anyone sees anything they want to add or change please do... This is the best info I have.

Not sure that you will need the friction modifier with the Amsoil since it has some built in already.
As for the diffs I think you may find that they hold a little less than the manual says. You will probably have some coming out the fill hole before you reach what the manual lists.

If you overill the front and it's an AAM 9.25 then some may seep past the axle and or piñon seal. Mine did and after some research I found it best to keep the fluid level about 5/8" below the filler hole. Also transfer case is ATF+4 as I recall.

I saw on Amsoils website they offer a separate friction modifier to add. Ill have to ask the guy I buy it from what he thinks. I probably will add it just to be on the safe side. Good info on the fill though. I figure ill get to this within a week or two so Ill update how everything went.

i suggest that when you do the rear diff, you put some of the oil in, like 1 qt then you put the requires amount of friction additive an then you continu with the oil until it reache the correct level

that way it wont be your additive thats going to spill out if you put to much

Thanks, thats a great idea. Amsoil sells a 4oz. container of friction modifier that treats 2 - 4 quarts so Ill just add one of those. I hadnt thought about which order I would add everything yet. Thanks for the tip!
