I just bought my van in October of 08. I had it 2 days and it was making a funny grinding noise when I would turn the wheel well that was the racket pinon. Now I have 3 new things going on I have a knocking noise coming from under the hood, Brakes are now making a grinding noise when I brake slowly, and when I go over a bump or speed bump I hear a clinking noise like something is lose and it just sounds lose what do you think it could be? Im taking the van in Saturday to the shop just wanna get an idea of what im in for thanks
