i would get it looked at asap
it could be alignment. does your tire wear evenly fron edge to edge? it could be bad bushng, loose suspension, or wheel bearing.
the self diagnosis to pull on the wheel is a good way to see if bearing or suspension is bad. but i guess you need to fix it professionally anyways so why not take it to a shop to have it looked at. i suggest a specialist or a wheel shop if it's an alignment only.
