Hello together, as maybe in the one or other post already read, I changed all the handlebars VA (original parts TRW/Lemförder), the coupling rods (Meyle) and the track rod head (Meyle) with my 3.0 TDI GP3. Axle is now also correctly measured and adjusted. Tires all around new. Nevertheless, I still have a vibration, which is sometimes weaker in intensity. Most noticeable at approx. 60-80 km/h, but also at 130 km/h cruise control. In addition, I feel a slight flap on the front axle with bumps on the road in urban traffic. The problems were already there before the exchange of the handlebars. Also with the summer rims and almost new tires. The summer bikes have 19″, the winter wheels 18″. Have tried different air pressures, sometimes at the lower limit, sometimes a little more. No difference. Vibrations are also there when I switch to neutral when I roll. Axialge steering on the steering gear have no play, wheel bearings at the front do not make any noises and also have no game. I can only think of the drive shafts now. But would it be new to me that a drive shaft clatters in unevenness on the road or only causes vibrations but does not make grinding/knocking noises. The cuffs are not ripped or greasy. One of you might still have another idea where the problem might lie? VG Ulti
