I’m on the highway today and when I change lane at 140 km/h, the car started to vibrate in the front. But it wasn’t easy to vibrate… it was like on a hump-piste or as if I was running over railway sleepers. Totally crazy! Then I went back to the right lane and thought about a damaged road surface. A few minutes later I tried it again and it happened again. The (concrete) motorway was obviously completely ok. Inside I noticed nothing. I also rarely drive 140 km/h. Are there forecasts? Muffler perhaps? I know that my track rod head is emptied out according to the workshop. Can that be the reason? I will have to have A.T.U. (forgive me) and a ride check done tomorrow. So that they don’t happen to be completely exploited, because I won’t be able to repair it… I’ll probably buy something there.
