Everyone losing their mind here is comical. There's no repair process or inspection available.

Relax ladies and gentlemen. These cars will be fine.
If this is a crankwalk issue, you can read about it, online. Thrust bearing failures, are the absolute biggest pain in the ass, ever. If you followed DSMs, back in the 1990s, you would have known that dealers were replacing thrust bearings on their 4G63 motors, and they would last a few thousand miles, and walk, again.

There were entire race shops that would absolutely not build one of these motors, even if you were replacing the crank, rods, and pistons, with something they sold, because they still walked.

And whats crazy is, they didnt start having the problem until the motors were older, usually more than 40K miles, but once the first one walked, people were having the motors rebuilt, under warranty, 2-3 times, because they just kept crankwaking.

They were literally rebuilding motors that hadnt crank walked, strengthening the bottom end with forged components, and putting the motor back in the car, and it would crankwalk, even after the stock motor had never done it. I hope this isnt a thrust bearing issue we are going to be chasing for years to come. I know, calm down, we dont know what the deal is, Im just sharing a story.
