Dealer is replacing rear wheel bearings to see if the noise will go away, and if that works, because they said the noise was actually coming from the rear, and the front.
What would cause a wheel bearing to fail......under torqueing, OR over torquing the centerlocks, or would this have no bearing (Pun) on the matter ?
Definately sounds like the right rear wheel. Couldn't find anything wrong. Not at idle. Sometimes going in a straight line. Seems to go away sometimes when accelerating.
Comes and goes....sometimes sounds like clicking at wheel speed, sometimes faster than wheel speed when going slow...
Mine too, but only on hard slow right corners where the left front is completely loaded do I hear it on the left front. I hear nothing on fast corners and nothing just driving on the street.
+1 on Peter's comments. I've noticed it the last 4 track events. It did get louder along with more vibration as well. I decided to ignore it, since I didn't have any issues what so ever. I'll keep my ears open for it this coming weekend on our season opener at the track.
Bump on this. Had the same problem after having the car aligned. Traced it to the RF tire rubbing ever so slightly on the inner fender well under hard loading of that corner. There was very slight evidence of the rub there. Car has -2.5 FR camber and -2.0 RR. It's going back to be checked out on Monday.
For those who experience(d) this problem in front, check your inner fender wells at the 10 o'clock position.

NO FREAKING IDEA what causing this.....
Might want to try dabbing a little bit of grease on surface where wheel meets the hub.
I had the same problem, clicking at low speeds but more evident after running the car for a while, especially when turning left in a roundabout.
Got to the dealer, adjusted center locks. Noise was still there. Checked if something was rubbing on front suspension, disk brakes, or related to the axle lifting but found nothing, click was still there...
Dealer experienced before that what was appearing to be in the front was actually coming from the rear, asked to leave the car for the week as they wanted to try something...
Now ... to me the most unexpected fix...replaced both driveshafts and the noise dissapeared completely, second time they did the same fix in a 997.
Ok... I think I have a real root cause to this issue and why some people see solutions after changing rotors, axles, only to return. For me, this is very annoying and as someone said above, could be flagged by a tech worker... though I had a shop take a look and they were unable to find anything.
I had this problem on one wheel and then several wheels. I was a clicking/ticking apparent especially after hard driving and extra apparent if you turn hard. It almost happened like a bad wheel bearing but the sound was much different. I tried removing and replacing parts one by one. I tried changing parts one by one, even changing the center lock mechanism and doing things like removing the keeper temporarily. I checked torque on every nut and bolt. I finally came to the conclusion that in my case, the root cause was rubber bits from the track. The rubber was inside the rotor hat and had been through so many cycles of heating that it basically turned into charcoal. You can see in the pic below that I can actually draw on the concrete with this "charcoal". If it was very hot the "charcoal" and allowed to cool, it could slightly melt and stick in in the rotor vents and hat. If the car was still hot (maybe coming off the track) the "charcoal" would not stick and bounce around like gravel inside the rotor hat causing a clicking/ticking sound. When I removed the bit and danced them around the rotor manually they made a clicking like sound.
I went wheel by wheel and took off the rotors and cleaned them... and the noise was resolved on each wheel. I'm pretty convinced this rubber was here even when the shop looked at it but they didn't remove it because it was just a quick check they didn't believe that rubber could be causing this.
At least in my case, I think I can mark this one as solved.

I’m convinced this is the issue too. Went through your entire ordeal and even replaced a bunch of parts one by one.
