I did actually replace them shortly after posting. I have since gotten rid of the X5 for a newer one. As far as your vibration problem, I’d be curious as to how it’s running. Do you have a vacuum leak? The reason why I ask is that you indicated it’s while your foot is on the brake at a light that you experience the vibration. It maybe a stretch but maybe worth looking into. I’d also be curious as the the condition of the steering rack bushings.
