Front & Rear Axle Gear oil

Hey all, i'm looking to change out my front and rear end gear oils. I've always used Amsoil in the rear of my 2wd expedition and Amsoil ATF in the trans of my talon. I just replaced the filters in my trans in the 250 and also refilled it will Mercon SP, however i want to change the fluid in my rear end now and i'm going to use Amsoil's gear oil, how much does it take and does it take 75w-90 in the front and 75w-140 in the rear end? also should i add any additive for the limited slip? i know i did in the expedition.

thanks,

6.9 pts for the rear and 6.3 pts for the front. I'm sure the Amsoil is good stuff. I would guess it already has the friction modifier in it. You should verify that. 75-140 should be good for front and rear. I use the same stuff in the front and rear diffs. Don' forget the transfer case. The appropriate synthetic Amsoil ATF along with the rear end fluid and you'll be running real smooth. It is amazing the difference good fluids make.

Oops. Forgot to say re-check your fluid levels after about 25 miles or so. Top off if necessary. Also run the front end with the hubs locked and the case in 2 hi or in 4 hi with the hubs unlocked once a month to keep everything free and lubed.

so i should run just amsoil ATF in the t-case? and how much? Also, do you know where the drain and fill holes are on it?

i totally forgot about the t-case, so thats good to know

also when i ran the amsoil oil in the rear of my expy i added the friction modifier stuff, and i cant remember what kind for the life of me.. but i would say that if i needed to add it for the expy i need to add it to the psd. does the front need it too? sory for all the questions, this is my first 4wd.

thanks a lot for the help!!

Amsoil Severe Gear did very well in a comparison with other gears oils, don't know where I saw it though. Yes, 75w-90 in the front and 75w-140 in the back. Don't add any friction modifier at first, add it 2oz at a time if you get chatter in corners.

Yeah, that's the study I saw. Ford spec is 75w-140. I think the 85w-140 oils are not always synthetic, but 75w-140 are.
