Legacy L 2.5i 2002 – front differential? whine

[myth]

Then go to the Subaru dealer and ask them to put it in writing. They should have no problem doing this for you. You will also have the benefit of this coming straight from the dealer, and not some random shop, so it shouldn't be possible to dispute it. In fact, anyone trying to dispute it in court should be thrown out on account of being a complete moron. Differentials fail in short order without lubrication, same as a motor would without oil.

 

Thanks for advise.

I asked it to both SoA and local dealer. I sent a e-mail asking how long it takes to damage diff.
