Well as some of you may know from some of my previous posts, I have been getting this high pitch sound when driving around 30-35 mph when the wheather is really cold. Well as my luck has it, the first time I brought it there they kept it over night because it seems to happen only in the morning or after not driving it for a period of time so the next morning was warm so there was no sound. Well brought it there again 2 days ago and they hear the sound, told me my drive shaft needs to be replaced, under warrenty so no need to worry. Just wondering if anyone has experienced this problem, or have had there drive shaft replaced.
