I first noticed it when i installed it on the car and ran it for the first time, it made alot of noise, so i just took it off, disassembled the CVD, and rolled the shaft portion on a slab of granite and as i suspected it was bent, about +/- 1-2mm off centerline in the middle of the shaft, it came that way in the V3 kit i recently purchased. I've ran it once in my RC8 and thats it.
