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....
