How badly damaged is my drive shaft?
My torque arm broke at the rear and rubbed on my stock aluminum drive shaft for a few miles. You can clearly see and feel a groove. How thick is the stock drive shaft? No, I'm not talking about the 3" diameter...the thickness of the material.
I would love to get a new chromoly shaft, but how worried should I be with this one for the time being? I don't race or launch the car ever. It has 18" street tires on it with the stock 10 bolt rear. The car is a M6 with a LS7 clutch. I have a 402ci motor pushing about 540 RWHP.

These stock driveshafts are very thin, I wouldn't drive the car until you get another driveshaft. Bob

The stock torque arm is prone to bending. I had a Camaro come in one time as the customer had a vibration. The torque arm was bent so bad the rear was angled downward and the rear springs were close to coming out of the spring pockets. Bob

Stock driveshaft is roughly .060 thick. Yeah that's thin. You are likely able to get across town at moderate speeds in that condition but I would avoid high speed runs and hard acceleration. I've actually seen that exact failure before and the driveshaft lived quite a while. Not worth risking though.

Yea I read it was .065 after I posted. It's hard to see from pics just how thin that is though.
All I needed to do for the time being was get across town to pick up my daily driver. Nobody local had a stock torque arm I could get fast so I had to temporarily fix mine by beating and welding it into shape.
I ordered a PST 3" drive shaft and forged yoke from Midwest Chassis. I also got their full length adjustable torque arm with relocation crossmember. Was not wanting or expecting to pay for all this mess, but I guess you gotta pay to play.

Gotta pay to play is right, but buying quality parts and installing them correctly is like a investment. Your car will last that much longer.
