    So, based off what I've read it kinda sounds like pinion angle or maybe something driveshaft related....but i'm hearing this whine/almost beeping sound above 55mph. And it only seems to be speed dependent. It does it regardless of engine RPM, gear, load, and clutch engagment. I'm fairly familiar with rear gear whine after a swap...and it doesn't seem to resemble that at all. It comes and goes over time. I've noticed it below 55mph, but it's faint at best. Only audible with windows up. Literally just bought it today.

    Current config of things I think may be of importance:
    -Stock 2-piece driveshaft
    -bmr lca's
    -stock 3.31s
    -sound tube delete

    Just looking for some input or verification. I planned on switching to a 1-piece shaft at some point, so if now is a good time, then so be it.

    Negative or unnecessary comments are not welcomed.

    I had a similar problem and turned out to be the seal on rear end trying to seize on pinion flange.
