Today was a bad day... car is undrivable - Page 7

is it possible that GM knows about this issue and already did some changes?

in your first picture (with the parts on the ground) it shows that there is no washer between the bolt and the retainer.

I will show you some pictures of mine (ZL1 A10 built APR 2017) where you can see lock washer and bolt showing almost 1/2-1/3in the other side....

I didn't check the size of the bolt (if it's 57.5 instead of 50.0) and the torque (45 or 37+45°) to make sure if it's the new setting but it appears to be good (Blue paint, lock washer, showing bolt the other side..)

Interesting. They may have updated the parts on the 17s. I will def check underneath as soon as I can to see if the repair included the washers. They mentioned longer bolts but nothing about lock washers.

Pretty sure mine looks like this too (Nov '16 build date/'17 model year). But remember we have the eLSD, so it's possible they have different bolts? I have checked mine, and my bolts all look good, and the blue lines line up.

My Nov'16 built 1SS (model year 2017) has these washers, but bolts appear to be shorter than yours. All bolts have a blue marker line that indicates non have backed out at all.
