Hello, I'm new to the forum and just came across this thread. I recently got a 2018 v6 1le it currently has 4k miles. I recently noticed the steering wheel was off center, so i took it to firestone for alignment. They aligned it and centered the wheel, but after a day or 2 the wheel was off center again. Could the bolts be a cause of this? Any advice or help would be greatly appreciated.

GunMetalGrey: You're confusing the single adjustment bolt, which is only used to align the car, with the two nuts and bolts that hold the strut to the knuckle.

I see, so the single adjustment bolt, which is only used to align the car, does not need to be discarded however if the two nuts and bolts that hold the strut to the knuckle were for some reason loosened and/or taken out (which I assume does not happen during alignment) GM calls for them to be discarded, correct?

Glad I found this thread. Checked with my dealer today and they were not aware of the single use bolts for the rear alignment (full track alignment booked for Friday). They will have them in stock in time.

It seems improbable that GM would use single use fasteners for alignment components, but I wouldn't put it past them. If the info about the TTY rear bolts is no longer current, it needs to be updated... |

So, I guess I can answer my own question... confirmed that both the rear camber and toe adjustment bolts are still TTY.
I went by the dealer today, and asked specifically about the rear camber bolts and toe adjustment bolts. The shop manager printed the service manual pages for my 2018 ZL1, and it clearly indicates that both of these bolts should be discarded and replaced with NEW bolts. It still amazes (and irritates) me that GM would use a single-use fastener for an alignment component. Especially on car they forsee having a high liklihood of track use. It's just stupid. Even more irritating is that the local dealer doesn't keep them in stock. |

Thanks for the update! The single use bolts really do seem like a fail! |

TTY? Not sure
Nick, in case you're still wondering, there are 2 bolts per rear side that are "supposed" to be replaced. One for camber, the other for toe adjustment. 4 bolts total.
I'm gonna throw in my 2 cents on this thread. At 4,000 miles currently, my suspension felt like it was a mess and the steering wheel was off center. I've always done my own alignments and get even tire wear and high mileage, so I figured let's get busy on the Camaro. So, I proceed to check the front. Toe-in was about +0.2*, but the camber was off at -1.0* and -1.1* driver and passenger side respectively. (Specs are -0.75*) The front knuckle bolts were SO TIGHT, I snapped my breaker bar where the socket attaches and my forearms crashed into the fender lip causing golf-ball sized dents. Luckily, I have a PDR glue kit and rods and know how to use them. I had to get my huge impact wrench out to finish the job. These bolts are supposedly reusable. Front alignment is now perfect and feels awesome. Moving to the rear, it's got toe-out of -0.2*. Worse is the camber at -1.6* and -1.4*. Specs are +0.2* toe-in and -1.0* camber. The passenger rear was visibly more negative than the driver's side and that really bugged me. Preparing for the worst based on my experience with the front knuckle bolts, I crawl under the car with my heaviest duty breaker bar and sockets. I also had my regular Craftsman 1/2" ratchet. I tried that first while noting that the factory blue paint marks haven't moved, so that's good to see. To my surprise, all camber and toe bolts broke loose easily. There couldn't have been more than 40-50 foot pounds of tension - maybe less. They just backed off with no issue. I'm reusing mine - and I tightened them slightly tighter but nowhere near 100+ ft lbs plus angle. If these were TTY head bolts (I build HP boat engines) I'd definitely be purchasing new ARP hardware. But, like many of you said, I can't imagine these bolts are one-use-only on an adjustable part. Why aren't the front? I just thought I'd post my experience based on what I read above where the dealer couldn't comment on whether they reused the bolts or not. B.S., they reused them. I suppose if I tracked a ZL1 I wouldn't take a chance, but this is a DD. Again, just my .02c
