I've noticed that when I go over bumpy roads at low speeds (nothing extreme, just normal everyday driving on regular roads), I hear squeeks and chirps. Hard to tell if it's coming from the front/back. Could be happening at higher speeds, but because of the outside noise at higher speeds, can't tell. I've done the hood stop adjustment/greasing with no success. I read in a thread about applying wd-40 on the front/rear sway bar bushings to see if it's those. Will that damage anything, or am I better off trying to squeeze some non-lithium grease or something else in there. I figured I'd try to lube them first just to see if that is causing the squeeks/chirps before I tried replacing them. Any other suggestions?
