Dry/Rusted Diff Splines
I just want to see if there’s anything else I should do when I’m working on it and I have the wheel off?

Don't get me wrong and I use Moly lithium grease for some applications, but for holding up against repeat type washings/water environments, marine grease is the ticket instead.

I got this because of it’s moly content, and waterproof.
Hence moly works grease for things like ball bearings since you have steel running against steel (dissimilar) surfaces at high rates, while spine against spine surfaces, your looking for more rust protection alone.
As for marine verses high temp grease, kind of the same thing, where is the question more water wash away protection, verses the grease staying in place as the temps get higher instead.
To bring this full circle, lets take Timken bearing in Harley wheels, since they get pulled/checked- cleaned/greases every time you change the tires on a Harley. For this application that you need the gease to hold up for the bearings/yet don't have a high void area at the bearings, the best grease your going to find is Red and Tacky, since it checks all the boxes for the bearings protected behind seals.
Lucas Red "N" Tacky Grease is a smooth, tacky, red lithium complex grease fortified with rust and oxidation inhibitors. It has good water resistance and washout properties. It has excellent mechanical stability and storage life. It is able to withstand heavy loads for extended periods of time. It can be used in many agricultural, automotive and industrial applications. Lucas Red "N" Tacky Grease is fortified with a high degree of extreme pressure additives that give it a TRUE Timken load much higher than other greases of this type. Its especially good for sliding surfaces and open gears.
So again, since we are just talking spine against spine surfaces, that its not going to be a high heat area, and we are just not wanting water to wash away the grease long term since water can get to the area, still will go with Marine grease being the best one for this application.

Thx for the all the info, I couldn’t find any of that brand grease in my area, I’m assuming this would work just as well?

The one near me, caries Red and Sticky name brand that I use for the Harley timken bearings, as well as their own name brand marine grease, Moly lithium ,high temp grease, and Anti-seize silicone greases, for a fraction on what other stores sell the greases for.
So on that note, can stock up to have different types of greases on hand on the cheap, for just about every application that you run across and need a grease for.
I bring this up since if you are using grease near brakes or any brake type rubber seal parts, you do not want to use a petroleum based grease since it will swell the rubber parts, and need to be using a silicone bases grease that will not swell the rubber seals up instead.
Note, on the diff seals (and Harley wheel seals), since the fluid in the diff is petroleum bases, the seals in the diff are fine with petroleum based greases.
