My 2009 X Prem Forester has been making this creaking noise for the last 3 or 4 months. I'm at 18,943 miles. I love my car! I just don't know whats causing the noise. Its only at slow speeds mostly. 20 and under. Its not loud but seems more noticeable on uneven surfaces or when the car is unbalanced. They replaced the front bushings ( sway bar) last week. The noise has returned and it seems to be coming from the rear end now.Back in for repairs tomorrow. Any ideas would be much appreciated since I know so little about repairs. Also, my gas cap tither snapped off yesterday. Is this still under warranty for the cap? Thanks to all for the help!
