I have a 2011 BMW 335i xdrive. I slightly hear a wobble sound, mostly pronounced when decelerating. Seems to be right side front maybe? wheel bearing? Balance or alignment? Differential? Any insights?

Toms response would sound about right to me. Usually if a wheel bearing is on its way out the door it will be more of a grating noise constantly. and normally only heard at a bit of a higher speed and only get louder the faster you go. As tom suggested check your tires for unusual ware and the cv joints and axels for looseness
