Ok this happened before until after i got an oil change, but i dont need on for another 1500 miles, but anyways when im in high mph's ill accelerate it to about 4-5 rpms and then ill let off and while the rpms fall back down i hear this grinding noise, and it sounds like its coming from front of the car.

sounds stupid...check your tie-rods. Because in my s-10 it did that for the longest time. So its just a suggestion.

grinding noise would be a bad bearing doubtful if bad suspension (it would have to be so bad it's about to come apart) the tie rods hook to the spindle(where teh tire bolts on)disconnect the belt and see if the sound is still there and hand spin each accessory I bet one of them makes a bad noise
