Dump hit with fully beaten wheels and starting ..

Hello community! I renewed my chassis together with my KFZti (Audi 80 B4 Avant 2.0) … 4 new bumpers (Bilstein), wheel bearings in front (FAG) , Achsmanschetten (Bilstein), Domlager (Bilstein) … after axle measurement so far as good … car is now like a board on the road … Only if I *full* hit to the left and drive to the right there is a dull blow … I would perhaps describe it in such a way that something out of great tension gets back into position … and we just don’t find it … I would say the blow comes rather from further down … not up from the cathedral / cathedral warehouse / pen plate … -> If I hit to the other side it is not! -> Koppelstand and track rod heads I controlled … tight! -> Cross handlers and carrying joint it can’t be either … notix has game (new). Does anyone know a tip? … experience that I could call you … thank you! Ben!
