Apparently very common in the E90 3-series. I originally figured I'd just have them changed.

Darren checked it out to ensure it was still safe to drive. Instead of replacing them, he suggested a more cost effective approach would be to grease them well and see if the noise went away.

Needless to say, after he greased them, the first thing I did was hit a few speed bumps at various speeds to bounce the car and check if the noise persisted. Glad to say the noise is gone for now. If the noise comes back I'll have him change the sway bar bushings to Polyurethane versus the stock rubber BMW OEM ones that are there now.

Another satisfied repeat customer !
Update: So after Darren at Alphawerx (now DC Motorwerx ) greased up my swaybar bushings I drove through the winter and didn't hear any scrapping/grinding until it was really really cold out but I did occasionally hear it when I made a turn. Guess when it's really cold out the grease is not as effective. Anyways I took it in a few days after spring started for a Oil/filter and had him replace all four of the swaybar bushings and grease them up. Today I am happy to say NO GRINDING NOISE even when I go over speed bumps. Nor do I hear it when I make turns.
