I recently bought a 64.5 260 Power steering car that had been sitting nearly 30 years. I replaced everything in front end. Including control arms.There is a lot of squeaking in the front on bumps. The alignment shims have fallen out several times. At first I thought the nuts were backing off, then shims fall out. The last time, they popped out with so much force, it sounded like hitting plate steel with a hammer. It is only on passengers side any ideas?
