The front end, right side i think, is making a humming noise, like when you go over a metal grate bridge, or the sound of an airplane propeler. it's not in harmony with the trans as I can turn off the car and still here the noise while rolling. it gets loude as you speed up, and winds down as you slow down. Also, if i put the ca in nuetral and brake, the front end bucks just before coming to a complete stop .... it doesn't do that if I leave the car in gear.

I hate to say it, but it sounds like something in the differential - transmission. The part about the noise and coasting fits a differential bearing noise. Making turns could put extra load on the bearings and gears in the transmission.
is it like a growling noise, or a metallic "metal on metal" noise, is it clicking? when do you hear it? Common for wheel bearings to go out on those in my experience. usually you can narrow it to a wheel bearing if when you sway the car, you hear a growling noise towards the heavy end of the car, meaning if you turn to the left, causing the car to naturally sway right, the right hand tire front or rear starts making noise, thats usually a wheel bearing. If its a clicking noise while cornering and especially when corning with acceleration, thats usually a CV axle. if its a metal on metal noise, that can be a brake pad worn to low, or even just a simple backing plate to the brake rotor touching and rubbing the rotor.
I agree with duane_wong on this one ( not like he was looking for my approval :) ), it sounds like a problem with the IWE ( Integrated Wheel End ) on that side. Quick test, when you are in 4H ( or 4L ) does the noise still happen ? I would say cracked vacuum line to the IWE, or a problem with the vacuum diaphragm in the IWE. You can test by having the motor running in park, and in 2H, and check the vacuum line at the IWE for vacuum. Make sure you test to the vacuum line, not the vent line ( ends in the engine compartment, not hooked to anything )
Most likely it is the RH front wheel bearings. CV Joints don't usually make any noise until you turn a rather sharp corner. I would advise you to replace the bearings and seals in both front wheels if the bearings are in fact noisy. Jack up the front and spin each wheel, you'll soon hear the sound of rumbling bearings.
humming noise usually comes from wheel bearings. did you change that with a new bearing? also choppy or worn tires can cause humming noise that sounds like bad wheel bearings. rotate your tires and see if the noise changes. if so its tires. also even if it sounds like its from the right it could very well be a bad bearing in another location.
Does the sound get louder as you drive, does it start to sound like a moaning or loud wind noise? If it does the most common problem is a bad bearing that the rotor bolts to and the axle slides through.
Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!
I think your right that its a bad bearing or hub. If your feeling it in the gas pedal and the floor, its most likely the front. If you can find an empty parking lot, try to get up to the speed it starts making the noise, and turn left and right. With the extra load being put on each bearing from turning, that will tell you which side it is.
your on the spot on both.
make sure the shock is tight on both end and have a rubber bushing bewteen the car fram and the shock. then try the shock first. take a look at spring while you have it out.
change the belt on the compressor and make sure the pulley is square on the compressor, and the any other pulley the belt goes.
