I've had my car in to the dealer three times and they still cannot diagnose the problem. I've replaced undercarriage cowlings (front and sides) and front struts but the binding, rattling sound is still there. Listened to Car Talk and when a listener described their problem, it was diagnosed as stabilizer links - which very accurately describes my problem. Why is it so hard for the dealer to find?

My wife noticed a rattling noise from the rear of the car. The noise was more evident as we drove on rough roads and hit pot holes. It sounded as if something was rolling around in the trunk. I looked at the shocks and saw nothing wrong. The trunk was empty and no parts were visibly loose. We took it to the Dealership very frustrated since we have had no issues with this car since bought new in 2007. The Dealership told us it was a stabilizer bar link. I had never heard of or seen such a part. They replaced it. Here we are 2 yrs later now with 73,000 miles and the stablilizer bar link is broken again. This is very frustrating. What can we do to not have this problem continuously, other than sell our car?

I have had this issue for over a year.I brought it to the mechanic when I first hears it and they couldn't find anything. The noise is getting worse so Ibbrought it again and they are telling me it could be the transmission and the front axle? I thought for sure I kept hearing it from the back. Any recalls on this issue?

I started hearing a rattling noise coming from the right rear of the car. I did some searching online and think that it is the right rear sway bar link, which I plan on replacing. Hopefully this will fix the problem.
Sounds like the front and rear to on my Mazda 3!

hear rattling noise from the back cannot figure out where is coming from
Great car other than this persistent rattle from the passenger side rear of car on bumpy roads. On the highway there is no problem. This web site is very helpful.
