It will most likely be the wheel bearing
Humming noise on the front passenger side of a 1997 Ford Explorer XLT may be due to a bad tire. Try to jack up the tire and spin it by hand to see if the noise is there.
What is the humming and vibrating noise coming from the passenger side rear from a small motor that is visible under the gas tank? is this another question????? or the answer to the question?????

Check your power steering pump A: check the front Left wheel bearing
I would guess on the passenger side near the firewall. This is the location of my 2000 4runner.
possibly your running RCAs on the same side as your power cable
we had rattleing noise on our passenger side van, it turned out we had to tighten the coil spring, and finally had to replace it
You are probably hearing the fuel pump, this is normal.
Worn passenger side front wheel bearings.
Some ideas coulb be something is lose and is just rattling or a mechanivcal problem under the hood.
I have a similar issue with my Stratus, except instead of humming, mine rumbles slightly. This answer is only speculation, but I believe that it happens because the power steering is stretched to the max while turned completely to the right. You'll hear a humming noise because the hydraulics are trying to pump even more fluid in order to turn further, but there isn't enough fluid in the system. Alternatively, your passenger-side front bearing could be worn out, but it would be much more noticeable than just a humming noise.
that is probably your electic fuel pump nothing to worry about
