Fellow Bimmernuts, I have read a lot about the dreaded shimmy at speed but please confirm if I have the same thrust arm problem. My shimmy (steering wheel shake) comes when I brake to slow down from speed. And the shake comes in at around 60 MPH down to 40 MPH as I am braking. I am going to replace the thrust arm in the very near future using BMA parts but if my problem is not related to the upper arm then I would like to know so I can get the other necessary replacement parts. I want to do the work all at one time, you know (I am getting old for this stuff, being a backyard mechanic for over 20 years). Thanks for all the help from the board and hello to all the San Diego threaders.
