Hey guys I just finished my m3 rear end swap today. I flushed the diff with the bmw fluid required and put everything in to spec. I took it for a drive and when in gear at any speed when im off the gas i can hear a whine coming from the diff. Does anyone know what this could be or what I could do to fix it. I hear theres an additive for lsds when they get sketch. Should I try that? its weird to me that it happens only when off the gas tho in gear.
yeah i got that too, going to try that liqui moly MOS2 anti-friction
