Axle fluid recommendations

[WarNose]

Thanks to this sight I just learned that I have the Sterling rear end with 4.10 gears and limited slip in the rear and a Dana 60 in the front.

What weight of gear oil should I put in? I know that I'll need to put an additive for the limited slip. Since the rear is limited slip is it safe to assume that the front is also? Will I be using the same weight for both the front and the rear? Right now I don't tow anything. I may get a small camping trailer next year but nothing heavy. Occasionally I'll do a dump run. Thanks.

The front most likely will not have a LS unit in it. If it does...SWEET!!!! I run 75w-140 synthetic and forget about it for years!!! And AC delco LS additive. I don't have a 10.25 at the moment but I have had a few and that's the oil I run in all my axles

This.
For oils I use Valvoline for motor oil to gear oil.
Synthetic is the what I run.

With the Limited Slip in the rear make sure you use an oil that is made for diffs with a LS, if you are a fan boy of one type of oil brand vs another you can always add stuff into the oil for the limited slip

75w-140 is what Ford recommends now, I run Lucas 75w-140 because it was on sale when I went to buy oil.

For the front dana 60 it looks like you need 75w-90, that's according to internet searches I just looked up, but I doubt you will have a limited slip in the front, not unless some previous owner put one in, you can always jack it up and spin the tires to confirm if your not sure

For whatever reason I can't find the sticky on this. Knuckle head I guess.

I read somewhere that synthetic could cause leaks on the seals. Anyone ever have that problem?

I like that finned cover!

Can someone please post a link to the sticky on this. I must be a complete IDIot because I can't find it at all. Thanks.

I actually couldn't find it either.
Best option is amsoil, you don't need a additive with amsoil.
