Most of people troubleshot the components that caused the squeaky noise by spraying lubricant to bushing and joints and the noise disappeared when they hit the right one. I sprayed and sprayed the whole darn 11oz can on every single joints and bushing, the noise sounds more clear and crisp LOL, what's going on? I hate to have to change all suspension components. I'm glad I ordered the whole set.
Question: The ball joints cause the squeaky noise or the bushing on the other end of control arms? How can a bushing make squeaky noise since it's rubber? All my ball joints still have rubber boot intact and look full of grease.
Please give me some hints anything to try to figure out before my control arms set gets here next week.

Thanks.......

My squeaking noise was comming from the lower curved arm bushing on the frame

I replaced the right one already, at least the noise seemed to come from the right!!
