I have an '06 envoy with 53k miles. When i drive i hear squeeking and rattling comming form under the car and can't tell if its from the suspension or something else loose. It seems to happen when im going around 35-40 and when im turning, also it happens whether I'm braking or not braking. I have 22's on it but they arent rubbing anything or touching anywhere. I dont think its the brakes because i hear rattling as well as squeeking.
