I have been on here snooping trying to find culprets for my front vibration problem. Went on a 450miler last sat and The vibration was the perfect pitch to make my hands go numb. I kept hearing a high pitch wine coming from the fron so I assumed the bearings had gone. Changed them and they did need to be changed. Still a vibration. So I bit the bullet and ripped the radiotor off and was checking out my motor mount. I found the mount was being held by the two bolts that also hold the radiator in place. All the other bolts were tight. My long winded question is, is that normal or did the third bolt that goes in between these two break off or was never put in? I'm so hoping that this missing third bolt up front is the culprit in my vibration issue. and before anyone starts in on me no I dont have THE BOOK. I havent had my 2006 R very long. Thanks guys and girls for your imput and suggestions on the bolt and or my vibration issue.
