As far as I'm aware no brass in the rear end...Where is there any brass or other "yellow metal" in a Series Alpine rear axle assembly? Definitely in the transmission, but in the rear axle assembly?
I like the "leave a brass key in the oil" test.....Turns out, there is a lab test for that. ASTM D130 puts a polished copper strip in the test lube for three hours at 100C (or 50C for fuels). The rating for my favorite gear lube is "1b" which means the polished test strip has a slight tarnish.I put a shiny brass key in the GL5 oil. I left it in there for over a year, and it looked like the day I put it in. Don't miss the "Oil Expert." He's busy trolling MK on another forum. But I hate to "" him but he espoused that they put additives in the GL5 to not hurt yellow metal.
