So which 75W-90 oil is hiding for rear diff under Porsche part number 00004330037 - Mobil Mobilube PTX 75W-90 or Mobil Mobilube 1 SHC 75W-90 or Mobil Delvac 75W-90 or Mobil 1 Syn Gear Lube LS 75W-90 ?

if I'm not wrong rear diff oil has to meet API GL-5 requirements ?

Starford - before the fix, aside from the whine - were there any other symptoms while driving such as hesitance to engage, slipping, etc.?

Glad you got it back and even more happy that it was all covered. That is always a huge relief.
