I have a 2004 Mitsubishi endeavor AWD 3.8V6, drove home from 300 mile trip stopped to fill tank and heard chirping/squeaking noise (similar to belt or idler pulley) at idle in gear no noise in neutral and increases as speed is increased. Today i checked further and it is coming from rear rocker cover area.
I do not want to take it to a dealer without some info from real pros like you on this site, anyone had this issue??
Help!!!
