Diff fluid

So I'm getting ready to change my diff fluid 2005 wk limited 4.7 and was wondering if when using Mobil 1 75w-140 LS do I need to add limited slip additive and can I also use the same fluid front and rear. I have read many posts but can't seem to find a for sure answer. Thanks

I don't trust any fluid to negate the need for LSD additive, so I always use it. I always use the factory additive also, seems to work better to me and it doesn't really cost much.

The 75w-140 is good front and rear.

NOW - Do you have QDII or QTII? If 'Drive', you need the additive. If 'Trac', you don't.

Not sure? Count the rear diff bolts. 12=drive 10=trac

So you've got quadra-trac. Standard open differentials that don't need LSD additive.
