Hey my forum friends. To make a long story short, I have had a vibration in the rear of my base m7, 2016 Stingray. After several tire rebalance, including a road force balance, the Chevy dealer has determined the problem is most likely the torque tube. Dealer says they have had several that have need replacement. Have any of you had the same problem? What should I know going into this procedure?
Nope, M7 trans is in the rear too just like the auto. Torque tube connects engine to trans for each transmission type.
Interesting so it's really another name for a driveshaft but instead of transmitting power from the tranny to the differential it is transmitting power, i.e. torque, from the engine to the transmission. Is this correct?
How is power transmitted from the transmission to the differential?

C7's have a Transaxle ... From what I understand the torque tube is actually consider part of the structure of the car with a drive shaft located in the center. A typical drive shaft in a rear wheel drive vehicles adds no structural integrity to the vehicle.

Thanks for any help.
No problem, just ensuw
they follow the correct procedure, check Pg 4

You are correct sir!
As shown in the kindly shared photo, the transmission connects directly to the differential.

Not a C7 but a good pic ....
This is the perfect explanation, and the picture is worth 1000 words. It is more than just a conventional driveshaft.
There's some good pictures of a 2014 C7 rolling drive train here.

the torque tube and driveshaft are 2 different and separate parts.
the driveshaft is inside the torque tube and connects the flywheel and clutch for the manual or the flywheel direct in the automatic to the transmission. the torque tube covers the driveshaft and bolts onto the engine via the bell housing at the front and to the transmission case at the rear.
to simplify, the engine crank turns the driveshaft which transmits power to the transmission, differential and rear wheels; the torque tube is the housing between the engine and transmission that protects the driveshaft from damage and provides stability and prevents some of the anti twisting moment that naturally occurs when you apply power to the rear wheels.
So it is actually the drive shaft that may cause a vibration?
The torque tube itself does not rotate only the shaft inside it
Can a new shaft be installed in the torque tube or is it 1 complete unit

Correct, the housing is stationary and I believe that they simply swap the defective internal shaft with a new one retaining the existing housing.
I need to visit my dealer as my car is torn apart right now having the fuel tank replaced and the tranny TSBs performed. Would like to see this in person.
I think the component that connects the TT shaft to the engine and tranny has a rubber/metal mounted type component instead of the conventional universal type joints. I have seen pictures of these going bad after yrs of use or abuse. This is prob. what has happened and not the actual TT itself. Like others said the TT is just a shaft with the rubber/metal type connections on each end much like the universal joints. Could be wrong but this is my 2$ worth.

more likely not the driveshaft which only vibrates if out of balance, damaged or if a coupler is damaged.
they are both separate so can be installed independently of each other. i believe they are both carbon fiber, and the driveshaft also has metal and rubber parts.
search google for this and you'll find lots of info including several threads from this site;
"vibration caused by misaligned torque tube in c7 corvette"
also, this thread is for a c5 but gives lots of pictures of how the driveshaft fits inside the torque tube;
I had a 1953 Chevy pickup truck, that had a torque tube, but back then it was called an inclosed driveshaft.
On the C5,6 and 7 the torque tube helps keep engine, transmission, aligned. It bolts solid to bell housing and transmission. The driveshaft and torque tube are aluminum.
By the way the C7 doesn't have a transaxle. It has a transmission bolted directly to the differential. Porsche has a transaxle. Transaxle has transmission and differential in one case.
Thank you so much; this is awesome and exactly what I was looking for. (One could say I was lurking/ following the driveshaft & torque tube discussion) Good stuff!
