The main thing about Diff or transmission oils is using the correct one in GL cat terms AND changing it twice as often as the Volvo Gods say.
Volvo dealership or Liqui Moly oil finder listed only as regards the transmission system.
The yellow metals story relates to some old manual gearboxes that need a GL3 OR GL 3 plus (Good for 3 and 4 groups) oils. It's a very long term issue and most of the flack was directed at Castrol Synthrax for listing GL 5 oils in their oil finder.
Marine grade bronze (It's a yellow metal like brass) was used in the good old days for a few bushes and even low speed shell bearings. It's real tough, does not corrode like brass or fatigue crack like stainless, BUT there are some oil additives that it reacts with. It will not react with Liqui Moly gearbox oil additives (They do a stop leak and one anti wear Moly additive).
