hi all im after a bit of help in finding out my problem b4 going to a garage so at least it will seem like i know what im talking about before they try and fleece me

the other night i went out in me car all fine and dandy then the next morning i went to work and there was a loudish "humming kind of noise coming from front passenger side wheel,
you couldnt hear it from outside just inside the car,
wheel bearing i thought, so had the wheel taken off gave it a tighten looks ok, though there is a bit of play with the wheel, (the humming did stop for a very short while) its now driving and pulling to the left,
getting out the car and having a look i dont know wether its me being paranoid but the alloy looks like its leaning ( like its gonna fold under the car) but only slightly i thought it could be my air in my tires as it looked like it was a bit flatter but the air is fine in it, im stumped as to what to get done with it and it might be somethin simple that my OH could do
i just dont wanna walk into a garage as they will prob try to say it needs a whole front end (hahahaha) so it would be great for any ideas, so i dont look a complete idiot, :-/
cheers to all for any and all suggestions
