#350 of 359 sea sick in the rear
Aug 21, 2012 (10:53 pm)
So our 2010 makes my 7 year old sick when driving for a long time. Headache on straight roads and vomiting on winding roads. Actually on winding roads i even feel a little dizzy. I thought it was my extra sensitive child and the way the road is, but we rented a Mustang and went on the same roads, drove faster and no sickness on my part.
I have 32k miles on it. I'll change the shocks in the rear because they are the usual suspect and because of the mileage. Any other suggestions? Are there stronger sway bars out there, for example?

Yes replace the rear shocks with (cheapest to more expensive)
and replace your rear sway bar bushings with Prothane polyurethane bushings. Note: you will have to buy 2012 Mazda5 rear sway bar bushing clamps because the original clamps from 2010 and under are way to small to accommodate the new bigger bushings.

I just changed my rear disks with Raybestos Advanced and inspected the rear suspension for the first time. This is going to be a really easy job.
The Monroe 5607 seem to cheap, indeed.
I followed your link to buy the bushings, but it says 04 and 05 Mazda3. I also bought the cabin air filter that says Mazda3 and not compatible witht the 5, although it's the exact same thing.
I just want to make sure.
Where do you buy the clamps, medcenter mazda?

One more thing: I had the privilege of riding in the very back recently and I heard this noise like a hhhhhhhr interrupted by an uu, so like a wow wow. The smoother the road the better you can hear it.
I used to hear this noise in the back of old Dodge minivans. I always thought they're worn out bearings. I looked for rear bearings for this car with not much luck.
Any ideas? thanks!

The link does say for Mazda3 but those are the exact bushing I installed on my 2006 Mazda5. They are the 19mm Prothane bushings. The clamps you can get from any dealer online or not. Make sure to specify that they are for a 2012 Mazda5 rear sway bar clamps.
I can't comment nor confirm that the cabin filters are the same for Mazda3, because I have always bought them as Mazda5 filters....sorry.
Lastly, I have heard from a few owners about rear wheel hub and bearing noise in which they had to get replaced, so you may have that as well. It could also be un-even worn tires partly due to weak shocks.

I found KYBs on Amazon. Bilstein does not make shocks for the 5. I replaced the rear shocks (how easy) and what a difference! I have always had a little trouble keeping this car straight - small corrections all the time - but no more!
The car is stable, the roads are smoother, the kids read in the back through 300 miles with no issues.
On the other side I want to respond to a previous post complaining about how thin the shocks look. I was not surprised by the OEM shock - it look beefy enough to me. The new KYB is even thinner. That actually does not matter one bit to the performance of this part. But all the other parts in the rear suspension did seem a little fleemsy to me. The arms are just bent tin. Same parts on Corolla are beefier. So.... I remember some people bought this car in Sport trim new for 15k-That's how you get there.
Anyway, front shocks are coming in! Happy for now!
#356 of 359 tires rotated
Sep 15, 2012 (5:20 pm)
So after changing the shocks the car is a dream to drive. Time to rotate tires. Costco said there are low and high points on my rear tires.... maybe time for new tires. They said probably the shocks were bad. No kidding!
I hope the tire wear will even out. I have these tires for 1 year and less then 10k.
I knew about this possibility before I bought the car but I didn't think it can be this severe and with such $$$ consequences.
If I would buy another one of these I would change the shocks right away. The expense will amortize by extending the life of the tires.
My question: will these square tires wear my new shocks prematurely?
#357 of 359 2008 Mazda5 GS Front Suspension Thump - Fixed!

Well, a pair of Monroe front struts fixed it. It needed the alignment too. It drives really nicely now. Back to standard squeaking from the back or occasional scraping/grating noise from rear suspension (that I don't care much about anyway). Glad this was taken car of!!

Replace your rear shocks if you haven't done so already. Our MZ5s love to dine on rear shocks quicker then you think. I also started getting the rear crunch noise and I replaced my rear sway bar bushings with aftermarket urethane bushings as well as beefier aftermarket sway bar links and the noise was still there. I lastly checked my rear shocks which initially I didn't think it would be because they had been replaced about 20K miles ago...well....the noise was actually coming from there. Replaced the rear shocks and now it is silent. Unfortunately rear shock design is weak and they go out very quickly (20K- 40K miles) tops.

Thank you for the advice. My mechanic told me that previous owner already replaced the rear shocks, so I will just leave it as it is. Thanks again for you replies.
