Bringing this one back. I just noticed the rapid ticking/clicking noise on mine on the right front while ripping through the canyons. The car has ~2800 miles on it, and I have previously taken off the wheels and performed the service bulletin. I think I did it early on — maybe at 1000 miles — as I was hearing an occasional tick when cutting the wheel during parking lot maneuvers and such.
I’m going to do it again, and I guess I’ll see how it goes. Need to go grab my expensive Snap On torque wrench from work first. As a side note, BMW has a really similar issue with the M3, M4, M6, etc. they actually released a friction washer that is placed between the wheel and hub. I might grab a couple and try them on my Z. They share the same bolt pattern, so I’m thinking it’ll work. |

I don’t think the service bulletin is really a permanent fix, but it seems to take care of it for a while. I just took my wheel off and cleaned everything up. Also did a little of what BMW’s bulletin recommends and lightly sanded the wheel contact surface. Haven’t driven it yet to test.

Here's the procedure that BMW came up with if anyone is interested. Seems like a better permanent fix than what GM came up with. They seem to think some of the noise is from the area between the rotor and hub. Obviously, it could be different between the two platforms, but they are very similar in design and the noise that is made.

Aluminum wheel + Steel hub + water/heat = galvanic corrosion. Oxide forms on the aluminum over time, wedging the wheel and making it rock, causing the ticking noise.
The grease applied at LGR is not as good as as the BMW insulator. Both will help slow but not permanently stop the corrosion. |

It’s amazing what we can learn from each other. Dealership cleaned the hub up during my oil change. They didn’t know about the bulletin. Luckily you guys got it for me. Thanks everyone for the input.
If it happens again I’ll see about the BMW fix.

I had been thinking the BMW friction washer may not work due to differences in wheel bolt/stud diameters, but both cars use a 14mm size. So these should work. I’m going to get a set to try, as they’re quite cheap from what I remember. We’ve done this to a few M cars at the shop.

Just took car in this morning for same reason; Clicking sound from left front area, only when doing hard right turn at low speeds <10 mph. I referred them to the above service bulletin. Lets see what happens...

If I think I know what you're saying then it's the ABS/ Stability control kicking in. I noticed this while listening to another ZL1 and SS 1LEs while at a autocross event last month.
Try making the same turns with the all the nannies turned off. |

Mine was fixed under warranty and has never returned. Has something to do with the wheel to hub interface.
