2009 Chevy Impala LTZ. My car has a loud creak coming from the right front suspension when turning left into a driveway or into a dip in the pavement. Dealer says they can't find anything wrong. Now I think the left side is starting to do it when turning right. Car has 27,000 miles on the clock. Any ideas will be most helpful....Rich
Well, your car is still under warranty, which is a good thing. You have plenty of time for the dealer to fix it for free for you. From what you describe, there are a few things that can make a noise like that. You could have a bad ball joint, or lower control arm bushings that are noisy. The strut could be bad, or possibly the upper mount.
Tie rod ends have been known to make a creaking noise when turning if they are dried out. A steering shaft usually just makes a clunking sound on turns when it is bad, so that probably isn't it. Worst case scenario is that the aluminum sub frame is making the noise due to a crack or a bad weld or damage. You may want to try a different dealership to see if they can find the problem, since there is a lot to look at.
Also, I would recommend going on a test drive with the technician on a route that you know it will cause the noise. Then you can point it out better and he might get a better feel for the problem.
