before 60 miles per hr ..is so quiet works great but after 60 starts doing a buzzing noise...one time i did accelerate at 75 miles per hr and then i put it in neutral just to see if it was the engine but the noise is still there even if i dont push the pedal .the engine develops great its only the noise ..does someone know something about it this noise is stuning.

 

I would say a bad universal, a bad cv joint or a bad wheel bearing

 

Don't rule out a loose trim piece. But for sure inspect all driveline components (bearings, universals, cv joints/boots, etc). Also, you may want to get the entire vehicle up on jack stands, transmission in neutral, and spin each tire to see if anything feels loose and/or doesn't spin smooth...
