I have this squeaking/chirping noise coming from somewhere on my 'Stang but I have no idea where. I tried the bolts that hold the metal piece on the back seat, I checked and lubed the eyelets where the parking brake cables run through, I lubed every possible part of the suspension, sway bars, end-links etc, and the bastard is still chirping. It will chirp when cruising on the highway. I can hear it when next to a guardrail. Does it over small bumps as well as large ones. I need help in eliminating this noise. BTW, Bullitt shock/spring package is on the way, well see if that fixes it.
