The old hubs we used ATF…not sure how they work now.

I don't believe there is a need for hub fluid on this machine (12 sportsman 850). That stopped in the late 90's or early 00's. That's when the hubs used to individually lock for 4wd in the magnum series atv and possibly the first sportsman atvs. Now that's all controlled in the front diff... all the OP needs is tranny/rear end oil and front diff oil. Much like our generals...

The only thing that is the same in the drivetrain of the Sportsman 550XP/850XP is the front differential layout.
The crankshaft is front/rear aligned and the transmission and differential are independent units with a driveshaft for the rear differential which uses 80/90 gear oil (preferred) or the older Polaris fluid.

Right. But I'm saying is all he needs is front diff, rear diff and trans oil... he doesnt need "hub fluid"..

that's all I was getting at. I'm well aware of how the engine/trans layout is different...

I read a post, or article, on the Amsoil Blue Bag lube and how much success other have had with it.
So going to give it a shot.
Now to figure out who my local dealer is...

Thank you all. I ended up using the fully synthetic Castrol TransMax ATF for import vehicles - same i use in my tacoma trans back in the states. I ordered some DirectDrive fluid via amazon delivered to my home in the states and head back later this week. Put the quad in the container for storage until I return. I’ll probably grab everything i can think of in next two weeks until i head back down here. Thanks to all for input. This place has some amazing topography.

Angle Drive fluid "hub fluid" is what Polaris specifies for the rear differential in his Sportsman 850XP so yes he does need hub fluid if he is going by Polaris specs.. or the SAE gear oil alternative.
DD fluid, Demand Drive Fluid is for the front Hilliard unit differential. This is not "hub fluid".
AGL is for the transmission.
There seems to be some confusion in some of the posts with the different lubricants.

What I was getting at with my 2 previous comments for the OP's clarity was he didn't need "hub fluid" for his hubs. They plain and simply don't need anything, they're just a bearing/hub...

he needed whatever fluid needed for front diff, rear diff and transmission, whatever that may be....

Amsoil has developed fluid that directly replaces the Polaris Demand Drive and AGL fluids -and- Amsoil dealers are everywhere -and- Amsoil was the first in Synthetics, they know what they are doing and can be trusted 100%. Go to their website and easily look up the fluids for your model, buy from a local dealer or they will ship direct to you. Easy, peace of mind...

I need to find a place that has Amsoil near me but so far not had any luck. The closest “large” town is Liberia CR and it is still roughly three hours away. The price of seclusion i suppose. did recently replace both rear axles and all my suspension pivots that had crystalized and broken apart. Muled all that in from the states but what a huge difference the new parts made. Suspension is tight and new axlesdont chatter like the old ones did.

I came across this while searching for alternatives and thought it might be important to consider some folks (like me) are in desperate need of alternatives not for the typical thought of cost but we reside in regions you simply cannot obtain Polaris fluids. The closest place I may be able to find Polaris fluids is over a six hours by car and hard to justify a crazy treacherous run to San Jose for some oil/fluid.

AMSOIL High-performance alternative to POLARIS Demand Drive Fluid and Polaris AGL Synthetic Gearcase Lubricant and Transmission Fluid

New Synthetic ATV/UTV Powertrain Fluid Combines Protection & Convenience
AMSOIL Synthetic ATV/UTV Powertrain Fluid (AUPT) directly replaces POLARIS Demand Drive Fluid and POLARIS AGL Synthetic Gearcase Lubricant and Transmission Fluid.
Synthetic ATV/UTV Powertrain Fluid is primarily recommended by AMSOIL for transmission/differentials and front drives in Polaris* ATVs and UTVs, offering the perfect combination of protection and convenience.
Protects in tough conditions It’s common to burden UTVs and ATVs with accessories designed to increase power or productivity, especially for UTV owners. Enthusiasts often add roof and door panels, a winch, a plow, skid plates and other accessories. Plus, how often do you haul a load of gravel or pull a trailer or other implement? This all adds weight, and a good rule of thumb is extra weight equals extra heat. Heat, in turn, causes lubricants to break down sooner, which places your engine and differentials at risk of wear.
Synthetic ATV/UTV Powertrain Fluid’s durable synthetic base oils naturally resist viscosity loss due to mechanical shear. It forms a strong lubricating film to keep metal components separated despite extreme pressure and heat from handling tough terrain or riding aggressively. It delivers confidence that your machine is protected in the toughest conditions, even if you have modified your ATV or UTV with accessories and tools that increase heat.
Replaces two OEM fluids
Owners of Polaris RANGER*, RZR*, GENERAL* and Sportsman* ATVs and UTVs have to buy two different original equipment manufacturer (OEM) lubricants to service powertrain components on their machines: Polaris Demand Drive Fluid* and Polaris AGL Synthetic Gearcase Lubricant and Transmission Fluid.* Buying two fluids is a hassle.
We designed AMSOIL Synthetic ATV/UTV Powertrain Fluid to solve this problem. Extensive testing in our mechanical lab allowed us to engineer a versatile formulation that provides excellent wear protection for transmission/differentials and front drives, replacing both OEM fluids. It eliminates the need to buy and store multiple products for maximum convenience. In addition, it offers Polaris owners a high-performance alternative to the OEM lubricants. Synthetic ATV/UTV Powertrain Fluid is Warranty Securer”‘ and will not void your ATV or UTV warranty. Available only in Easy-Packs Synthetic ATV/UTV Powertrain Fluid is available in easy-packs only. The award-winning easy-pack reduces mess and hassle, making tricky lubricant installations easier. It also eliminates the need to buy a lubricant pump, offering added value.

Does it come in quart bottles or just the bag?

Just this quart bag

Just sayin' the Hilliard diff only holds a bit over 8 oz of Demand Drive fluid. So a quart will get you almost three changes.
That's probably less expensive than any alternative.
