My 08 H3 Alpha makes a clicking sound, sounds like a nail in a tire. When I first start it, I hear it a little bit, but when I accelerate, the sound accelerates too. The best way to describe the sound is that it is 3 clicks, then a pause, and the rhythm gets faster as I accelerate. I can go months without hearing it, then I'll hear it for a few days. Could it be a solenoid somewhere ?

 

If you have Chrome Wheels check for flaking. Mine was peeling on the inside and contacting the Caliper.

 

I do have a lot of flaking from my chrome wheels, think you are exactly right. Never would have thought of that. Thanks for the idea.

 

I like Frosted Flakes........... They're GR-R-REAT!



Flaking wheels, not so much.

 

Check drive shafts. Maybe u joints or CV joint failing?
