Torque Tube issues
I'm considering buying a used C7. Doing research on C7 maintenance issues I see a lot of talk about torque tube bearing failures and the causes. My question is do most C7's end up with T/T bearing failures. Is it a when it will happen or an if it will happen type of issue. Thanks in advance for any suggestions. SB

No most don't have issues. It's a small percentage that have issues. If you sell 100,000 C7s and 1% have an issue it's going to seem like a really big deal when 1000 people are posting about it.

I do not think it is a real common issue with the C7, but as with any part on a car, there can be failures - and the point at which things fail can vary widely. If the car checks out by a good Corvette Tech, go for it.

I'll add my 2 cents. I purchased a '19 GS late last year, and now with a little over 20K on the clock it's developed the rattle I've heard so much about. It doesn't do it consistently yet, but it's definitely there. I'm having it checked out this coming Monday. And as the previous poster mentioned, It's the reason I bought an extended warranty.

I've had a C3, C4 and a C6 and I have never heard of this problem before I had a C7.

My 17 Z06 M7 had the bearing fail at 16k miles. This took out the torque tube and the clutch. Total cost of the repair was 7k….on a car I had only driven 3k miles since purchased. I am the second owner.
the research I have done would indicate it’s far more common than the general population of owners would like to believe.
I would suggest if you pull the trigger keep some cash on the ready just in case. I was going to put a 2650 on mine and I’m glad I didn’t or I wouldn’t have had the reserves to repair the car right away.
unfortunately I have only driven the car once since the repairs as I blew out my knee and had surgery. Hopefully it holds together this time, car and knee lol.
Best of luck with your purchase, I hope you find a good one. I really like mine, other than this incident my only other complaint would be the expensive consumables when tracking the car.

I wonder out of the 1000 failures, how many of the cars were abused. I definitely drive mine different now compared to how I drove it when I first got it.

My car did see track time but no abuse, at least not while I had it. I have driven a multitude of cars far harder for 3 times the miles without issue. I think it’s just a roll of the dice.

I believe the TT's were introduced on the C5's when they moved the transmission to the rear. The C7's were the first to have AFM, which might be a contributing factor.
