Just had control arms replaced for a creaking noise, same noise is back after 2 weeks and even louder

I drive a 2016 chevy sonic turbo, I had my suspension diagnosed and repaired for a creaking bed sounding noise about 2 weeks. My mechanic said it was my front drivers side control arm, also recommended to have the other side replaced as well as it was getting old. It's been driving fine for these weeks and now all of the sudden the noise is back and even louder than it was prior to being repaired. It sounds awful particularly when turning right, and I can't quite tell anything looking loose or worn at first glance behind the wheel on the front right. Does anyone know what this could possibly be?
