Hello, I’m so slow to despair. It’s about a supposed imbalance that comes from the rear axle of my GP1 V8. This is reflected in vibrations, which, for example, allow the passenger seat to tremble. The whole phenomenon occurs at speeds between 90-115Km/h, whereby apparently the driving time or external temperature also play a role. Thus, for example, nothing can be noticed when the thickness is still relatively cold. After a few kilometers, however, it is then true The speed range in which the vibrations occur is also shifting. I have already had the wheels balanced 2 times, changed from front to rear, had all 4 wheel bearings renewed and had new brake discs installed in the rear. Unfortunately, nothing brought about an improvement. I have now possibly the cardan shaft in suspicion, which caused these vibrations. Does anyone have to have similar experiences? LG supersterse
