Hello, I had lost the rear part of the cardan wave about 4 months ago. It had been noticeable with a light and later stronger plucking. Until this then simply fell off on the highway. Had then changed the whole cardan wave and the car ran again 1A. But now after 4 months it starts again the same way, when driving or driving in the first or second gear is now again this plucking… … you hear it less, but it feels more. As soon as you faster al This is 40 Km/h, it can’t be felt any more. Did one of you ever have a similar problem? Did I do something wrong during the assembly? If you look at the cardan shaft, you can’t see anything. Can it possibly be the hardy disc or that a screw is too loose or too tight? The car has a manual circuit. I’m afraid that the same thing will happen again.
