Spindle to strut housing bolts- anyone know the size?
 

Here I am months later, still trying to chase the noises and clunks in the front suspension. So far:
Stabilizer bar bushings
Control arm bushings
Sway bar links
Ball joints
CV boots
Steering rack

Still have a metallic clicking noise at idle speeds going around turns. And a horrible clunk with a jerk of the steering wheel to the right whenever I hit the brakes hard at highway speeds. None of the above parts has made any difference. Not much left but the u-joints in the steering shaft, and the upper spring perch bearings.

In the meantime, I still have a pull to the right all the time. New front tires, cross rotating front and rear tires made no difference. Alignment showed that the best I can get out of the left front is -1.5 degrees camber, and the right front is -0.6. That would definitely cause a pull to the right.

Want to try the H&R Triple C concentric camber bolts, but they don't list them per car, just in shank diameter and overall length. They replace the upper hub-to-strut bolt and have a concentric "C" on them to allow camber changes by turning the bolt. Too cold and snowy outside to crawl under the X5 to pull one out and measure. Any chance someone might know the bolt size?

Thanks, never thought to check Realoem for a bolt size.
