If I get a stubborn problem that keeps pointing to new parts, especially a dangerous problem like yours, I will take the time to completely do the job again. Remove the swing arm bushings and remove the steering bearings completely, again. Possibly revise your installation procedure too.
Sorry I don’t have a magic easy bullet for you, but you are describing a dangerous unrideable condition. It’s worth the effort. Good luck! Let us know what you find.
