change diff gear oil?

I am coming up on 100K and I was looking for input on changing the diff gear oil front and rear. The manual states it is a lifetime gear oil and only change if it has been submerged. I am the second owner and I have no idea if it has been serviced. The front fluid looks and smells good the rear is black and smells.

The truck is a 2011 F350 crew cab, SRW.

If yes what do you recommended??? Ford, Luca, Royal Purple, additive Y/N etc.

thanks

Great question on the limited slip or e locker. I have only had the truck for less than 3K and do not have the window sticker. I will have to look at the rear and see if their are any #s I can pull and cross reference to find out more info.

if your 4x4 selector pulls out and you get the lock light you have the e locker. simple no sticker needed.

Those are some great sites thank you very much.

Looks like 3.55 rear with electronic locking axle.

Looking at replacing with Lucas Synthetic 75W-140 Gear Oil or their Heavy Duty 85W-140 Gear Oil. Has anyone ran these in their 6.7s and did you add the Ford additive?

Not sure you need an additive with the electronic locking rear. The additives were used with the limited slip that used clutch plates and steels.

Per 2011 F350 Owner's Manual

http://www.fordservicecontent.com/Fo.../11f23og4e.pdf

Page 410

Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford Specification EST-M2C118–A for complete refill of limited slip Ford axles. Ford design rear axles contain a synthetic lubricant that does not require changing unless the axle has been submerged in water
