Did they attempt to realign the front end? Maybe they did not get everything back into spec perfectly? Can't speculate your exact problem but know your front end alignment is a series of adjustments that can vastly affect handling and steering even though they are for the most part imperceptible changes. You have to ask questions in order to get answers.
