im agreeing with phil47 and gixxerboy63 about the noise youre hearing from the front end . im experiencing the same noise right now and iknow exactly where its coming from.From the worn out bushings . Just to cover all the bases i am going to replace the lower, upper, control arms bushings ,ball joints,sway bar links,using powerflex bushings to restore the quality ride i use to have when it was new..FYI you can purchase the control arms and all the other stuff @ bimmerworld .They can press the polyurethane bushings into the control arms for $10. ea.
