Check the hubs today and noticed the oil was milky thru the little sight eye on the cap, I’ve heard a lot on Lucas hub oil, what do you all think

Lucas hub oil is all I use in mine.

Change the seals, check the seal ring where rear seal rides for grooves, replace if so, and put in the lucas.

I'm replacing the rear seal and the o-ring that goes in the gutter hub area, and of corse removing the rear seal tore the rubber part so i can't read the part #

[j archer]

so I got the part # finally of the seal #ad25278e, crossed the part number to the parts store here and the depth of the original seal is .54 and this one is 1/4 so half the size will that be ok, but is the same id and od

If you haven't already done so, post this over in the Ranger Forum. In a nutshell, the oil can get milky with just one drop of water, which could be a result of condensation over time when backing warm hubs into cold lake water. Unless there was oil leaking out of the rear seal or the front seal, there is no need to replace either seal. I had those COOL Hubs fail twice on me, both times while on a trip. Changing seals is no fun in a gas station parking lot. If it were me, I'd replace the oil with grease and never look back. And, NO, I would not use any seal but the exact correct one. You can get seals from Ranger or almost any decent marina store.
