Hellos,
the SVXes use a viscous LSD, right?

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
