Vibration Under Braking from >45 mph

[spngr311]

All,

I thought I'd share my experience with my wife's 2001 X5. Her X5 was experiencing vibration under braking from speeds greater than 45 mph. It wasn't consistent, but it happened often enough to be of concern. She was due for a brake job, so I changed the rotors and pads. She still had the vibration. I did some searching online and many posts pointed to the front suspension arms (specifically their bushings). Also, the Bentley manual mentions this as the culprit in the section related to the front suspension arms. I ordered the four arms, installed them last weekend, and the vibration under braking completely disappeared. The original arms showed cracks in the bushing on the front tension arms, and the ball joint boots were torn on the control arms. The car is now smooth and solid. Thought I'd put this out there in case people were having similar issues and just wanted a quick answer.
