What's up fam, today with my Z, I discovered a whining noise that will probably drive me crazy. So far I can tell it's *most likely* something in the drivetrain. It does not occur while revving in neutral, so it's probably not any of the belts. When coasting it also doesn't appear, meaning it's linked to the drivetrain. When in gear and keeping on the gas, I can hear it. I didn't do any diagnostics further, but so far that's it. I don't think it's wheel bearing, as it's high pitched and not rough. I did install LSD not long ago, so it' might be related to it, but I don't know what....the bushings were lubed, all was done good and no problems identified yet. Today I'll do some more diagnostics and post an update....
