New rear sway bar bushings did not work. In fact they are noisier then the old ones.... back to the drawing board. I love my MZ5 but I really wished Mazda would find a definite and permanent fix for this rear horrid suspension squeak...

So I decided to spend another $25 and bought the new "beefier" 2012 Mazda5 rear sway bar bushings and braces. I had to use my dremel to bore out the inner part of the bushing to make it fit, but after a few passes I was able to make it fit nice and snug. Noise is still there....
I also tightened all the bolts in the rear suspension as one dealership had reccomended but...nothing.
Ahh somebody please find the permanent fix for this...

I think I finally found the culprit to the legendary rear squeak noise while driving slow in uneven surface.
the control arms
the sway bar bushings
Its none other then the upper rubber seat for the spring. The noise comes from the spring rubbing on the rubber seat. I pulled the spring out, cleaned the surface and applied heavy duty white lithium grease from an actual jar with a brush (do not use the weak spray can form it doesnt work) and I applied it generously. Installed the spring back in there and voila! No noise.
Now... it may not be a permanent fix but it will certainly silence it for while. I may pull it again when it starts doing it again and I plan on wrapping the upper two three coils with heavy duty teflon tape and adding more grease. I hope this certainly cures the issue once and for all. Just thought I'd share for anyone that is interested.

I hope this cures the problem as well but I think that what you have found is a problem that over time has been caused by the poor design / specification of the control arms,sway bar bushings and shocks. In my case when the sway bar bushings were replaced the old ones were absolutely deformed and shot.
I think what was happening, in my situation anyway, was that because the bushings were not holding the sway bar tightly enough, the rear suspension was actually bottoming out over larger bumps (causing the coil springs to fully contact each other) and thus causing the loud "poing" when the spring released in addition to the annoying squeak.
I'm curious to know why you chose to enlarge the opening of the new bushings as you mentioned in an earlier post. It is my understanding that the sway bar should be held firm and not turn freely inside the bushing or else the excess movement of the sway bar reduces it's effectiveness. Did you try to install the "beefier" bushings "as is" first?
Since I had the replacement sway bar assembly installed back in September (ie. slightly larger sway bar and beefier bushings...see earlier posts) my Mazda 5 hasn't made a peep from the rear end...yet!! I guess time will tell. Anyway I hope I'm not coming off as preachy because I want the problem solved as much as you do . I just think that Mazda under speced some of the rear suspension components on the 06 - 10 models. It just seems suspicious to me that the 2012 model Mazda 5 has a slightly larger rear sway bar, bigger sway bar bushings and redesigned shocks. Take care davicho.

Hello slurp, thanks for chiming in...I have been very relentless in solving this annoying issue and I totally agree that it stems from poor design. Unfortunately for us first gens the issues will remain while the 2nd gens (hopefully) will have them solved.
At any rate, the reason I bored out the new (2012) style bushings was because they would not fit on the old (2006-2011) style sway bar. The new bushings have a squared hole with a lot more rubber (beefier) around it hence replacing the bigger u-clamps as well. I will assume that the new style rear sway bar has a square notch right where the bushings mount, hence the squared hole on the bushings. While I did bore out the inner hole to fit my sway bar. I did it slowly and a little at a time so that i wouldn't over-bore. Believe me these bushings are on "tight". Well tighter then the old ones. They are so tight that I had to use grease to be able to slide the clamp over them and secure it to the subframe. I dont know if greasing the upper spring seats were the answer or if it was a combination of both...greasing the seats and the beefier bushings, but the noise it completely gone for now...I mean not a single peep. I guess time will tell.

#328 of 361 2 5's same issues

Had a 2007 touring and now have a 2009. Both started creaking around 44k (of course after warranty). Anyone ever touch base with Mazda about the problem?

I dont think Mazda has definate answer or resolution to this issue...however, a lot of MZ5 owners have tried fixings on their own i.e
-replacing sway bar bushings constantly as soon as they start making noise
-lubing up exsisting sway bar bushings
-replacing sway bar bushings with aftermarket ones
or in my case...I replaced the rear sway bar bushings with the 2nd generation (2012 and up) MZ5 which are way bigger and beefier. I had to do some alterations to make them fit on my 2006 MZ5 but no noise since then. The easier way but also a little more expensive way is to replace the rear sway bar, sway bar bushings, bushing braces with the 2nd generation MZ5 parts. They bolt right up and they are imo bigger, beefier and better.
