Diff fluid and transfer case fluid 2008 E350 D60 NP271

[boywonder]

I've been thinking about changing some fluids in my 2008 E350 with stock limited slip FF rear, D60 front axle and NP271 transfer case.


The rear is stock limited slip FF, the front is open D60.


I'm assuming any ATF in the transfer case and likely any diff fluid in the front D60 but I understand there are some specific requirements for the stock rear limited slip.


Recommendations?

Spicer Manual

This is a link to the Dana/Spicer Lubrication manual that I found recently. It is probably far more info than you were looking for, but it is pretty comprehensive!

Hopefully what you are looking for is in there somewhere.

On my rear differential with factory LSD, I used Mobil1 synthetic gear lubricant (not sure the grade) but didn't add the friction modifier. I had it, but wanted to try first without. So far so good (10k Miles) doing mud, snow and other shenanigans you are not supposed to do with a van.
For what I understand, if the LSD do not grind, let it be.
For the transfer you need specific transfer case lubricant.
