First thing, check power steering fluid level and tyre pressures. Then get the front in the air and take a look at the steering rack bushes - 3 of them. And if everything looks OK get someone to turn the steering back and forth and feel if there is any movement in the steering rack or steering rack ends (inner and outers) - you can also move the wheel back and forth by yourself if nobody is around to help you.
Then when everything is good as new, get your wheel alignment done again.
