I have installed BMR lowering springs, UCA (poly bushings), and mount on my 2010. I've adjusted my pinion to as close to -2 as I think I can get. I'm hearing a faint "whirling" or light rubbing noise coming from my rear end. The faster I go the louder it gets. It's not loud enough to be annoying but I just want to make sure nothing is wrong. I can really hear it when I remove the back seat and take her for a spin. Have any of you experienced this after a UCA and mount install? Other than this faint noise, everything else seems to be good to go. Thanks!
