I’ve noticed a creaking sound coming from the left front wheel when I go over a couple of particularly large speed bumps. I have had a lot of problems with the suspension in this car, and have replaced the front struts, the front right control arm, and the sway bar links and bushings. My best guess is that this noise is coming from the front left control arm, as it has not been replaced, although my current mechanic says that the front left control arm is fine. Also, it has been under 10 F here the past few days, so this could also just be a result of the cold weather.
