Really need some help, car pulling left and right

One of my tires started feathering really bad so I took it to have it checked out. The place I took it to aligns old cars as well as new but they are known preferably for old cars. I suggest that you find a old school alignment shop in your area. Anyways it turned out to be the lower control arm bushings was worn. He said it wouldn't hold alignment. So I rebuilt the entire front end. I don't know exactly what he did but he climbed underneath my car with a pry bar and pried something (lower control arm somehow)then came out and told me the news. After I got the front end apart and looked at the bushings he was correct. You might be onto something. Do you hear any squeaking noises when you are on the road? I know when the lower bushings go they squeak.... mine did.
