Chevy Impala Rattle Clunk In Front End

Suspension problem with my 2007 Chevrolet Impala. There is a clunk type noise. Can describe as a rattle as well. It is in the rear of my Impala. I can hear it when we drive over bumps or just when turning the car. The sound is on both sides. The shop checked the rear shocks / struts and said that they not the problem. What can cause my noises?

Answer:
This sounds like a very common problem with the 2006, 2007 Chevy Impala. There is a rear stabilizer shaft in the rear suspension. It has 2 link rods, 1 on each side. The ball / socket on each end of each link can get worn and loose. This will cause the noise that you are hearing. It the car has less than 36 k miles, this will be an item that will be replaced under factory warranty. Expect about 1 hour to complete this repair. See picture below. It is with the rear wheel removed. The Tech is pointing to the link rod.

Question:
I have a problem with a growling noise sound in the front end of the my 2002 Chevy Impala. It gets louder the faster i drive. Sounds like a roaring sort of grinding. It changes when i turn the wheel left or right while going down the road. A have read it could be a hub or wheel bearing. My 2002 Chevy Impala.

Answer:
Yes, this does sound like one of the front hub / wheel bearings. While turning the wheel and the noise changes or goes away is a dead give-away. The load on the wheels change when driving and turning. Example: The load is taken off the right front when the car is turning to the right. So if the noise goes away, then the right front bearing is the one that is the problem.

Question:
I Parked my car and went out to start it again about an hour and a half later and I was not able to turn the key. I installed a new lock cylinder and it will not start. I also noticed that my steering wheel does not lock anymore. When I put in the new cylinder I am able to shift the shifter with out Pressing on the brake pedal. I put the old cylinder back in and the shifter and brake pedal work normally but car will still not start so I reinstalled new cylinder. To make things even worse I cannot turn the key all the way back to the off position to get the key out. Can you please help me?

ANSWER

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.

Answer:
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.
