My LF lower ball joint has been squeaking everytime I hit a bump as of a few months ago. I just noticed it's not squeaking anymore. About a month ago, I took a hypodermic needle and drew in 1/2 oz of Free All, a very good penetrating oil, and injected it into the ball joint boot. It still squeaked, even after a few days and I thought I wasted my time and forgot about it until tonight when I realized it no longer squeaks. I guess the medicine just needs some time to take effect?
