One more thing. Noises are probably the most difficult thing for us to help you with. But, I've even gotten help with noises, by describing where they come from and if they are engine speed, wheel speed, etc.
Keep on trying to describe the problem and answering the questions. Sometimes just the act of putting it in words makes you think through the problem in a way different than before and makes you come up with your own solution.
Best of luck,
