Thanks, I'll do the detailed searching again.
Actually I've been studying the rear differential oil change topic quite a heavily and my car is manufactured on 07/2011 so it's basicly the first manufacturing month where the BMW Hypoid G1 is required for the differential oil. It seems to be/ require 75W-85 GL4 version instead of earlier GL5 grade, more common type of 75W-85 differential oil. I cannot get a big picture why they have limited the oil so after 07/2011 but it must be some quality, etc. finding since the earlier differential gears. Or otherwise the mechanics has changed on that month from some reason.
I couldn't find the exact 1:1 aftermarket oil to replace the BMW Hypoid G1 oil from markets. Tips for this one would be useful.
What is your experience, does the oil change typically remove the noise issues or is only way to fix the issue to change the bearings, etc. inside the differential drive?
