It sounds like a tire is rubbing against the fender well but that cannot possibly be the problem. A newly installed, JDM Y21 tranny w/ LSD is most likely the noise I'm hearing. Do the non-helical tranny's with factory LSD make a creaking noise at a low rpm turn because the LSD is trying to give power to both wheels instead of just the one that needs it?

Somebody help me out! I think the sound is normal coming from the LSD, but I'd like to make sure that's exactly what I'm hearing.

Thanks!
