So guys I can’t really get along with my problem. I’ve been looking like wild here, but I didn’t find anything really suitable. To the problem: If I start/accelerate with a speed between about 1500- 2500upr, then comes from somewhere behind a knocking, rumbling, polter, bollern, .. It’s not quite easy to describe. Sounds kind of rhythmic, getting faster with the speed. If I stay below 1500upr at the speed, the noise does not occur. It also doesn’t come, w It doesn’t always happen, but it’s about 90%. It gets/is stronger when I accelerate in a curve (re/li doesn’t matter). It’s definitely more dependent on the speed than on the speed, or from about 80-90km/h there’s nothing more to hear. I have the feeling that it gets worse when it’s loaded. I actually shut out the tyres. They’re very new (winter Michelin, about 10tkm), and it happens at very low speeds. I don’t believe dampers either. I don’t believe wheel bearings, because they would certainly report even more at higher speed. I checked the exhaust and found nothing suspicious. Had once raised it up, and a wheel off. Was not to be seen, or the difi. siffs quite easily. I then waved at the cardan shaft. It can be moved at the camp already very rough back and forth (approx. 1-3cm). I thought already to have found the enemy, until I read here that the camp, or the rubber That’s why I had to be soft (how soft???). I couldn’t control the hardy disks. In August I had the gear oil checked (only control, nothing changed). The difi has not yet been tested. The DTI has no brake belts in gears, so it can’t be. My guess: I still type on the bearing of the shaft, and possibly one/the hardy disks. I’m grateful for useful hints to seize the culprit! patrick
