i bought a 98 used durango and have been hearing some strange noises. when i take slow turns i hear a rubbing sound coming form the rear. the noise was made when i had stock wheels on and my after market ones as well. also i might add it only makes the noises some days, not every day. any suggestions on what i can check. people have told me about power stearing fluid leaking, but im almost 100% my noise is from rear. can it be something in my rear suspesnison gone bad...any common problems you can think of that sound like this. please help me out guys. thanks
