1995 Audi 80 Cabriolet Steering wheel position / Steering gearbox

Good day municipality, after poltern on the front axle I changed (again) completely on both sides: – cross handlebars with carrying joints – coupling rod – track rod and head – dome bearing (41 mm height) Afterwards an axle measurement was carried out. Now I have the problem that the front car “slips” in slight curves and I get an adrenaline boost, really unpleasant. I then went to the master at the axle measurement again to test if something was done wrong Everything is fixed, everything is fine. His opinion was that the steering gear was defective. Sounds understandable to me, but I ask for your opinions. The position of the steering wheel at the straight run is also very strange. Sometimes it is about 20° to the left, sometimes 20° to the right, sometimes right (see pictures). Has someone perhaps experienced this and/or has an idea? Nice weekend and greetings Stefan
