Heres he problem. I keep hearing a spquealing sound from the power stearing, a/c and the alternaor 'system'. i took it apart to check the timing belt(took all the belts off and everything likethat. well ever sese its been dointaht squealig around 1,500 to 2K and then it stops, i thought it was the power stearing belt so i replaced that. well one day ishut my door a little hard and i heard the squealing so i started kicking my tire and it makes that sound so, its nothing to do about the car running. it seems like when the car vibrates a little it makes that sound. also when i was driving i put my car into neutral(goin about 20 mph) and shutmycar off(5 speed i have) and when it was going about 15 and below it started making that sound also. does anyone have any ideas?
