Cracks in torque tube housing welds WT....
***UPDATE***
Talked to the guys at VA Speed, evidently the lines I'm seeing are from the welding process. It is caused by the impurities in the metal being drawn toward the center of the weld. They showed me the same marks on a new weld. Learn something new everyday.
Here are some pics of the torque tube housing from my 2004 A4. Looks to me like I have cracks on the center of the welds at each end of the tube…. Anyone seen anything like this before? The front has the cracks all the way around, the rear is only on the top half.
Looks like I’m in the market for a 2004 A4 housing, if you have one let me know. I don’t need a the driveshaft, I have a brand new ECS U-joint one setting here.

That is what I decided to try after thinking about it overnight. I'm going to check with VA Speed today and see what they can do.
I'm just glad I caught this when I did, could have caused some real damage.
Maybe I should give up my quest for the 8's....

You have found the reason first hand why we came up with our "Torque tamer" Mike. On a higher powered car like yours, the entire drive train lifts upon hard launches. Basically the entire drive train wants to spin in the opposite direction of the tires.
On a solid axle car you would have a tq arm that mounts to the body, the Corvette uses the tq tube and the weight of the drive train, which is normally sufficient, until your making big power. You would really be surprised how much the drive train flies around and flexes under the car upon load and high power.
Here's the thread where we have it listed, it's pretty inexpensive, and will keep this from happening again. btw, I would just weld it too.

I'm curious how many cars have these cracks, I have only seen one other thread showwing anything like this. On that one the whole housing ripped apart.
