Hi all! I've been having an issue with my 2003 Jeep Liberty. For months my step-dad and I cannot figure out as to what is causing a rattling/clinging sound coming from the front driver side wheel/break area. It has always had a slight rattling noise for about 3 years now, but has gotten louder over the years. Last summer the entire breaking system was replaced. My step-dad replaced the caliper about a month ago and it's Still making an awful noise. Here's how it will start off: when I start my jeep and take off it's quiet but it does make a slight noise. The more my jeep runs and warms up- the louder the noise gets. The only thing we're coming up with is the rotor could have gotten warped which is why it's still making the noise. Any mechanics might know what else it could be?
