If my wheel bearings were bad wouldnt the abs light come on since it did once before over a year ago when....?

Hello, i am having an issue with the front tire feeling like its wobbling. It makes more noise when i turn the wheel to the right, the guy at pep boys said the left side felt like it had play in it, but we feel it more on the passenger side, anyways, if my bearings were bad wouldnt the abs light cone on, because over a year ago i had them replaced, i believe with the cheaper ones from a shop and the abs lights were on that time. Im thinking its possible that it could be just a bad tire cause the tire is kinda bald and old ehich i plan on replacing this weekend, and also my rotors are pretty old and bad which i also am replacing probably tomorrow or this weekend , i have them in my trunk. I went and bought two front bearings for it thinking that was the problem but now im wondering , "why isnt the abs light on the dashboard coming on if they are, i even had a diagnostic test done last week when i got my cat, oil switch and something with my IAT sensor fixed and it didnt show up on there either. So, my question i guess is, could it just be a tire and rotor problem that is making the wheel feel like its wobbling off the car, but doesnt do it all the time, usually happens either after i drive for awhile or when at higher speeds, if i turn to the left it doesnt do it as much or at all but to the right it does more and mainly. Please help me someone. Thanks for anyone that gives me some incite or solutions, i would greatly appreciate it, its drving me nutts especially after so much money i put into this car already. Oh yah, i also think my alignment is bad too which im getting fixed this weekend too because my front tire is bald on the corners but not as much in the middle and a tire guy said that could be to do with my alignment which i do kinda agree with being that the steering wheel sometimes shakes when im driving too. Thanks everyone for your time. Sincerely Roy
