well, about two days ago, the Blazer started making some verrry strange noises. First came a quiet clicking sound, then came the loud clicking sound, then the pulsating squieling, and finally the long squiel. It only does it when my car is moving, not at a stop. Also when i drive in reverse there is a clanking sound like someting is dragging on the ground....but there isnt. What the hell is wrong with my car. I took it to have all the fluids changed, and that didnt help. It sounds like it could be coming from the rear end...but im not sure. Let me know if you have a remote idea of what this could possibly be. Big Jake Drive it like you stole it!
