07 cx-9 with 12k on it has clicking noise when turning the steering wheel at low speeds, like in a parking lot, sounds like its coming from front end. Also clanging noise from front with very low speeds going over bumps. Dealer said they hear noises, but can not figure it out.

The clicking sound in the front end of my 2007 CX-9 resembles a worn out CVC joint.. only happens at low speeds while turning sharply. I have brought it to the dealer several times, after 2 new struts and some bushings the clicking sound is still there. It doesn't sound like a brake issue. The car overall has performed well in Montana conditions, but desperately needed some new treads.

I hear a clicking sound on my CX9 only when it has been sitting for a while. My opinion is that I may need new brake pads soon because it sounds sort of like the shims/pads are a little loose and have a slight shift when putting into gear.
 
HOWEVER....
 
The front end sound that I do have is a crunching/squeaking sound when going over speed bumps and coming out/in of driveways at low speeds (5-10 mph). It is very annoying and it sounds like a old 1970's pick up truck that has noisy leaf springs. I am ready to just replace the sway bar bushings and links because the struts seem to damper just fine plus they are expensive, so I rather start with the cheaper fix. The reason I am doing this, is because my previous Mazda5 had a similar sound in the front end, and the culprit was remedied by replacing the sway bar bushings in accordance with a TSB issued my Mazda.
 
Is anyone else experiencing this noise?? I have posted my concern a few times before, but I get no response, so I am begining to think that this is just a individualized problem with my CX9 and not a mass production issue. Please chime in and just let me know if anyone else has this issue. Thanks!

i have the EXACT same squeaking (high-pitched) noise...especially after damp weather (dewey mornings) and low speeds as you said as well as with soft turns at those lower speeds. i can't tell whether it is from the front or rear and it annoys the heck out of me. i heard about a TSB but i thought it was for '08 models and i have an '09 so i didn't think it applied. have you ever taken it to the dealer? i plan to ask my local Mazda service dept when i take it in for my first oil change in a few weeks. let me know if your "quick fix" approach works!

I hate to say it but if you have heard about a TSB that applies to only 08 models, don't believe it because it probably also covers your 09 as well. The Mazda5 TSB supposedly only applied to 06-07 models...guess what... there was also 08-09 models ( and I wouldn't doubt 2010 models) having the same issue. I tried researching for a TSB as well for our CX9's but I could not find one. Let me know if you get the TSB number or if something gets resolved when you take your CX9 into the dealer. I will do the same if I get to do my fix before you do. Unfortunately I am out of warranty and I am on my own on this one. I really don't want to spend money on parts and repairs that are not going to remedy the problem at hand. If I had warranty, it would be a different story....

The dealer did claim that there was some brake caliper slop and it was a manufacturer flaw. Also the struts and sway bar bushings had been replaced under warranty and the clunking has subsided(maybe the new Cooper Discoverer CTS tires helped dampen the ride), but the clicking/clunking noise is still obvious while turning sharply. This car has only 26000 miles on it and the noise has been there for at least 15000 of that. It does remind me of the 1979 Honda Civic I drove in my youth that had worn out CVC joints that clunked as you turned... funny how it sounds the same.

just came back from my dealer for a routine service and get this squeaking noise checked out. turns out my backing plate was bent and touching a rotor causing the noise. they bent the plate back into shape and now no more noise. thankfully, it was not a major issue.

Apparently there is a TSB for the "click-click" sound and the low pitch squeak in the front end. The TSB is #02-006/09, I got a copy of it from my buddy at Mazda and since I am out of warranty I just bought the part (two, one for each side) that needs to be replaced and will be getting it installed at my work (non-Mazda dealership) hopefully by this Tuesday. Part number is #TD11-34-380B which is a top strut mount. It is the same part number for either side depending wether you need only one or both. I need both replaced because I dont really know which side or if both make the "click-click and squeak" sound. I really hope this fixes the problem, I will report back as soon as they are installed.

***UPDATE***
 
Had both upper strut mounts (#TD11-34-380B) replaced on Saturday by a master tech here at my work (Moss Bros CJD - San Bernardino). TSB is useless. After replacing both strut mounts and being out of $200 including labor...squeak when going over bumps or pulling in/out of driveways at slow speed is still very prominent as before and "click-click" when shifting into reverse or drive from a stand still is still there as well. Do not waste your time and money (if you are out of warranty) in this TSB, it solves nothing!!! Mazda please do your research a little bit more in depth next time. BTW, I also had my tech lube up the sway bar bushings and check for leaky struts. He lubed up the bushings and the struts are in perfect visual condition. My next attack is the sway bar links and if that does not solve the problem, perhaps the sway bar bushings and finally front struts.

***LAST UPDATE***
 
I finally fixed my left or right front suspension squeaking issue when going over speed bumps and/or going up/down driveways at very low speeds. It turns out that the fix to this is quite easy and very cheap. So I am screwed and out about $200 thanks to that misleading TSB that Mazda put out...Thanks Mazda, like I said, next time do a bit more research...
 
Nonetheless, the noise comes from the actual bump stops that "should" glide over the strut's rod when compressing. The problem is that the bump stops are either made of a material that does not glide smoothly on the shaft or they are way to tight to glide on the shaft. The cure for this is a simple squirt od white lithium grease on the top and bottom of the bump stop.
 
Jack up your CX-9 and lift the dust boot that covers the bump stop squirt some grease. Lift the bump stop and squirt grease on the bottom part as well. Glide the "now" smooth bump stop up and down to lubricate and distribute the white grease on the strut rod/shaft. Repeat this process on the opposite side (left or right) and voila! no more annoying noise/sound.
 
Since this part is somewhat exposed to water/snow/other external elements this procedure may or may not have to be re done. Hope this helps!
