everytime i go over any sort of bump or even little descrpancies in the road my rear end squeeks. Sounds like someone havin sex on an old bed. heh.. I'm still under warranty so i brought it to the dealer to have them look at it. They said that the noise is coming from the aftermarket trailing arms. I'm new to the mustang platform. What are trailing arms and does anyone know where in the rear i can find them. Ford told me to have them lubed up and the noise will go away.. but they wouldn't touch it because it's not factory. Sheisty bastards.. lol
