So I am 2 months or so into ownership of my beautiful 69 convertible. I have came a long way into working out all the small issues this car has. I had taken it to a highly recommended front end alignment guy. I was under it with him and watched his every move. I had initially came to the conclusion the front end had been rebuilt. He came up with same conclusion. Only needed the upper ball joints replaced and had it aligned.
Problem is I have a knocking noise on both sides of front end from time to time. Obviously hard to describe noises but I am gonna do my best. Sounds as if someone tapped the frame or fender with small hammer. And it does it periodically. And I never know which side its going to be or when. Now I am not a mechanic but have fairly good mechanical and trouble shooter skills. I feel as it maybe the springs are shifting or something. I am also wanting to say they may supposed to have some rubber bushing that go on the springs. I have nothing to compare it to.
I can jack it up and turn wheels all day and it never happens. Also it does seem to happen on entering drive way or going over a bump at slow speeds
