Rattle From Rear Suspension Due to Loose Stabilizer Bar Links on Mazda Mazda3

Problem Description and Possible Solution

A Loose rear stabilizer bar link can cause a rattling noise from the rear suspension while driving on rough roads. Our technicians tell us if the rear stabilizer bar and links are not found to be loose, there are updated sway bar bushings available which should correct this problem.

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 the same thing happening on my car. What is the general cost of something like this to get fixed?
I'm also noticing a rattle noise from the rear of my car when doing lower speeds or going over speed bumps.
Clunking noise coming from passenger side rear. Usually occurs when I am on a bumpy road or going over railroad tracks. Husband looked under car and the swaybar link is bent and nut is rusted so you cannot tighten it. Going to dealership to have it looked at this weekend. This really should be a recall item!!!
At about 24,000 miles I began to hear this same rattling noise everyone here is describing at the drivers side rear of the car and although I continually asked the dealership to check the car to find the problem, a problem was never found. I thought it might have been the exhaust bouncing around after being told there was no problem because the car still rode well. 4 years of this noise and 4 years of complaining about this noise and the dealership has finally, finally found that the coil spring on the drivers side rear is broken! I have been driving around like this for 4 years! Even the service manager said a broken coil spring is rare on a car - they better do this work under the warranty, even though it's now expired!
Rattling sound coming from rear suspension while driving on broken and rough pavement and speed humps.
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.
- #3 hatch with all the bells & whistles that were available back then...
The drivers side rear suspension squeaks intermittently and when you go over bumps or turning at low speed (<10mph) & you get a 'railway-car' type clatter sound when you hit a bump almost every time no matter how fast or how small it is. I have taken a look, but cant find anything loose or damaged... will revisit with a closer inspection on the stabilizer bar links to see if they are the issue.
Driving down the few and far between Boston smooth roads there are no issues with a 'floating rear end' or any other tell tale suspension failure signs.
BTW - the service station I have been using could not find anything last service!
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?
Clunking sound while driving, seems to be coming from passenger side, but hard to tell. All struts/ shocks have been replaced and the noises hasn't gone away.
I have had the exact same issues with my car for several years now. Sounds like it is about to fall apart. Taking it to dealership Monday to have it fixed.
I had rattling noise coming from the rear of my Mazda3 on road bumps and rough road since I bought the car used with 71K miles. At the time I thought the plastic spare tire cover was making this noise and there was nothing I could do... Fast forward 24K miles and 2 years, I realized it was not the cover making the noise, but a worn rear sway bar link. Replaced it at the Mazda dealer (after they replaced the rear strut which did not solve the problem). 10K later - this noise again. Now I new where to look! Helpful tip: To identify the bad link, use the bottom of your fist (preferably, in the glove:) to hit the end of sway bar where it attaches to the link. If the link is bad, you will hear the same noise! $30 OEM link from Ebay and 45 minutes of work - noise is gone!
Rattling while going over bumps in the right rear tire especially. Also a strong Knocking nose while breaking in the Right Rear. Had Front Struts replaced because of same issue.
Rattling noise at back of car when going over railroad tracks or rough roads. Replaced all the shocks and it still rattles. It is so annoying. Now when the heater is on a clicking noise can be heard in the engine compartment by the front right wheel. Equally annoying!!
