Wagon pulls to the side when load changes, ground waves and after steering impact

Hello Moose rider, my C70 II 2.4i, switch, 150,000 km pulls strongly to the side and steering wheel moves accordingly. This happens with load changes (then to the right) at ground waves and after steering impact (e.g. AFTER completed lane change, it then pulls further strongly to the right, so that I have to steer against against). With the thick summer tires the problem is even stronger than with winter tires. I then had brake discs and documents change VA and HA (was due anyway) and in addition both crossbars with bushings, track bar with head left (track bar right according to free workshop still OK) incl. axle measurement. Nevertheless, the problem is still present. Tires are evenly run off, air pressure also OK. , I wonder if the workshop should not have replaced the track bar right. To the right it pulls the most noticeable…Or other reasons are possible?…I mean, what about a missing screw of a bearing to have read about that was the cause in a similar case, find the thread but no longer do you have ideas?????
