what weight gear oil for "wet" front hubs?

I use 80-90 oil after checking w/ Spartan. I use a turkey baster to pull out old oil and then add new. I top off when necessary. I've got 105K mi now and bearing seem OK.

75w90 is synthetic. 80w90 is not.

As per the maintenance instruction sheet from Spartan, 90 weight Gear Oil in mine. I use Lucas Brand.

OK I found some 80-90 gear oil rated for different purposes including heavy trucks. Nothing else on the shelf around here.

Topped up the drivers hub and will keep an eye on it.

Thanks again.

Thanks for the replies. It seems that the 75-90 is common.
I need to take it for it's spring test run this week before our first short camping trip of the year.

That's what I was told but I've never had to add any. I have it changed every oil change....but like the engine, never needed any additional.
