Viscous LSD?
 

Hellos,

the SVXes use a viscous LSD, right? http://www.cars101.com/subaru_svx.html

Reading a bit about that, Wikipedia claims the viscous diff center has basically failed by 60.000 miles and must be replaced.

If it is indeed VLSD, what are your experiences with this? Did you ever change your diff center, did you notice any difference etc

Cheers

At 197,000 miles, mine still works.

Wikipedia isn't exactly the place I'd source for car information, plus that's probably in a general case.

I think it depends a lot on how much abuse it gets. If the rear tires are different diameters, then it would fail more quickly, etc. I wonder if there's a way to test it to see how well it's working.

So just inspect and change the fluids as according to schedule and bob's your uncle?

Yes, and use the Subaru LSD gear oil.

These guys sell it: http://www.rs25.com/forums/f14/t1188...l-bottles.html

Email them and tell them you want just the LSD oil, they seem like good people to deal with.

I thought the center diff on the automatics was a clutch type?

We're talking about the rear diff.

Thanks a lot, folks.
