Viscous Clutches/couplings are generally quite well sealed, heretically sealed since at time they operate with a great deal of internal pressure. Only a professional shop would be able to change out the fluid.
Post about 2002 VC's were so severely derated absent TC you had no real "locking". From what I can find out at Subaru your '05 has a standard open differential with a VC between the 2 "output" shafts. If there is a sustained difference in the speed of those 2 shafts, front/rear, then the VC fluid should stiffen dramatically thereby "locking" the 2 shafts together.
On a 4 wheel dyno the VC in my '00 F/awd RX300 would take about 15 seconds to re-apportion engine torque ~70/30 F/R. The '01 came with TC and VSC thereby making the VC useless and as such it was dropped entirely from the RX330 model.

"It's not even a debate," says Jim Vurpillat, global marketing director for General Motors Co.'s Cadillac brand. Luxury-car buyers expect all-wheel drive to be available on any serious luxury sedan, he says, which is why Cadillac is offering the technology on its new compact ATS and large XTS sedans, as well as its midsize CTS model.
What is debatable is whether all-wheel drive delivers enough safety and performance benefits for the $2,000 to $3,000 extra charge car makers typically add to the price tag, as well as the mileage penalty that the extra weight of all-wheel-drive hardware still exacts in most cars.
Consumer Reports compared the slick weather performance of a Toyota Corolla to a Land Rover and concluded that the CorollaŚwith its thin tires and light bodyŚstopped much more quickly in snow than the burly, all-wheel-drive, luxury SUV."

OK, but how well would an AWD Corolla perform compared to a FWD one? That's the real question.
Articles like that get headlines, though.
Plus AWD is to supposed to help you get through. If you had to get your wife-in-labor to the hospital to deliver your first born in the middle of a snow storm, would you take the Corolla or the Rover?
Answer: your Subaru. It's lighter and brakes better, but still offers AWD.

K, there's a project for you. Put the fuse in on your Forester and see if you get stuck this winter.

That just feels wrong. An idiot light pops up that says "FWD", as if FWD is a defect, so you know how Subaru feels about that.

"..how well would an AWD Corolla perform.."
Considering it would of necessaty be a F/awd in which the clear majority of the time it would be FWD only......

Yup, front axle would already be slipping by the time any power was sent aft.
