i started having this sound some time ago, when it was cold out, after the first start of the day pulling out of the driveway (driving straight) it got this metallic sqealing sound, but im not sure where its at, because it used to happen so rarely. today i drove about 50 miles on the highway, and when i got off and started driving in the city it started making that sound when taking off, or slowing down somtimes. but doesnt have anything to do with the steering. or brakes. and does it only while cold or hot it seems. im totally lost here..thanks in advance
