Squeek/chirping sound from front end

I have a 97 Acura cl. There is a chirping/squeeking sound coming from the front end when passing over imperfections in the road. I am stumped as to what is causing the problem. The ball joints have no play. I have replaced my sway bar links. I replaced my front motor mount, all the others looked ok. My wheel bearings have no play. Shocks are also good. The bushings all appear fine. I am thoroughly stumped and could use some other peoples insight. Thanks in advance.

Could be anything made of rubber including control arm bushings. Time to spray some rubber lube on any suspected thing and try a test drive. Good luck; those front end squeaks can be hard to find.
