Just "re-discovered" this thread and have an update. The wobble in the front was caused by loose lug nuts (RF). I was so focused on finding another, more complicated solution, that I hadn't considered the most obvious and simplest fix. Fortunately, no harm was done while the nuts were loose, but this incident has made me more aware (again) of the importance of the driving experience. Proper maintenance, quick inspections (and corrections while still relatively inexpensive) of the simple things as well as the hi-tech, high-dollar stuff we worry about. In exchange, your BMW will reward you with a great deal of driving pleasure, instead of trip after trip to the garage. Then there is the withdrawal and inconvenience of it all. This is all part of my quality of life. M3 forever!!! Lug nuts! Who knew!
...feelin' kind of silly right about now...
