See how the spring in the right side of pic4 has rubbed into the shaft in pic 3. That should be smooth. That's the rattle you hear from the ZL's

At first I was like WTF but now I see it. Pic 3 shows the damage the best.
I have 8200 miles on mine and it's stock...

that is insane. I can't believe GM continues to allow this shotty design in such a high end car like the ZL1.
I want to replace my coupler so bad but I'm terrified of losing my warranty on my S/Cer.

riddle me this matt. the wear shown is 9k miles so does that wear lessen or subside as the car breaks in or will the wear proceed at the current rate through the mileage of the car thus wearing through in xxx miles?

it may look worse than it actually is. we have to remember g.m is standing behind this design for 100k miles. that would be roughly 1900 superchargers in '12 and 9k superchargers put on '13's so far. that would be serious cost to warranty all of them if they are all wearing at this rate. my thought is the initial wear happens quickly due to the break in but then subsides to a tolerable wear rate soon after. at that point some rattle and some don't.

I can say that I have seen 100+ LSA motors apart. Among those for example; a 140 mile ZR1 that was fine, 1500 mile CTS-V that was worse than this, and a 40k CTS-V that was fine... Out of all the ones that were taken apart, I'd say 80%+ of the ones that we take off (Its part of our package so we always change these) have impacted the shaft from the spring. In this case we also deburr all 6 pins because the breakdown of the isolator starts elongating some of the bolt holes and the pins get a bit scored. |

The only rattle is the loose nut behind the steering wheel... Thanks willhe for the clarification, I was trying to be too slick in just posting pictures and letting everyone take a look.. The other side of the shaft 180* out from that has very few marks on it, so I'd contribute that to run-out while the isolator/tensioner was breaking down. |
