I have a 2001 4Runner and during the cold days my truck would make a squealing noise only while accelerating. After riding for about 5-10 minutes it would go away. I have had all of the belts replaced, and it is still doing it. If the temperature is warm, it will not make the noise. I have had the truck lifted, so I am not sure if that has something to do with it. The dealership doesn't seem to know what is causing it. In addition, the noise seems to be coming from under the passenger seat. Does anyone have any advice?
Thanks
