Hello. I drive a model-kept SLK 230K, EZ 8.2000, with 125000KM and have the following problem. On good level roads he has a precise straight out. But with wavy roadway or shock stimulation, even at low speed, the steering wheel runs almost shock-like times to the left or right. The Tüv recently had nothing to complain about at the HU. He says chassis, crossbars, wheel bearings, eim Bospurständen etc. everything io. The chassis also makes no noises like grinding, clacking Nothing. I had the track measured at Boschdienst. Was and is io. I also changed the steering damper. However, no change. I drive the summer like winter tyres at the front as well as at the back with original 16 inch rims, tyres 205/55/R16/91V. The problem occurs in the summer like winter tyres. The chassis is original. So no lowerings or anything else. That’s already my fifth SLK. All others had this problem, even with tyres Not. Perhaps one of you has good advice or advice. Thank you in advance.
