something broke

[te.ringer]

I went outside to put my 1973 duster away for the winter ,I thought it had a flat tire on the left front but tire was inflated and way up into fender so much that I cant turn the steering wheel drove the car last weekend to a car show to get some drive time no problem at all.Jacked it up and found nothing out of place except t bar adjusting screw not in right place so is it possible the socket in the lower control arm spun? or are there other places to look. I was lucky this happened in my drive way and sitting still . many thanks
