Rattling noises from the front suspension while driving over rough roads can be caused by defective front sway bar bushings. Replacing the bushings with the updated design is a common repair.

2007 Mazda Mazda5 35,000 mi,
Not fixed: rattle or clunking at the front with slightest road roughness, especially during first 20 minutes of driving. Goes away . Some days no problem.Has been happening for months.
Problem is ONLY on rough roads. I have a house in the NC mountains ( zip 27879) and I have to drive about 1 and 1/2 miles on a gravel but well maintained road, then up a gravel drivewy. I notice the noise mostly coming down my driveway slowly.... The clunking noises from the front end sound like the wheels are coming off. When I get to the paved road the noise stops completely.
I had this issue as well. I let the noise go on for a few years and it progressively got worse. I finally had the sway bar bushings replaced. I am surprised by the cost of what others are paying. Mine were replaced for less than $50.

Just bought the Mazda 5 at 40000, a few months later at 50000, already replaced a rear shock that was making excessive noise when going over the slightest bumps. now a similar noise is coming from front. Mechanic says it was stabilizer links, and replaced them (300 dollars), and there is STILL NOISE. Mechanic now thinks it is stabilizer bushings. ahhh

Rattling sound coming from front suspension. First replaced front struts, then lower suspension arm and sway bar link. Result was same clunking and rattling sound. Read some fix at a mazda forum was to replace sway bar bushings with the upgraded ones. Found a replacement from Auto Zone made by Energy Suspension. Problem solved!
replacing sway bar and bushing today 12.10.12

clunking noise from the front on bumps or uneven road. Sway bar bushing was replaced by Mazda with a new redesigned ones. Problem reappeared again at around 75000 miles
Rattling noise. Dealer Service replaced rear sway bar/ bushings. Still no improvement. Maybe now try the front!! Really irritating and makes me uncomfortable

Rattling from front suspension when the car is cold. Stops when the car warms up.

Our mechanic tells us that it is just a noise...the part will last for years and never fail but it will always rattle and a replacement part might rattle just as bad. We will turn up the radio.
Had noticed a knocking or rumbling noise from the suspension that had developed over time. More noticeable from the front, and more so when colder, and going at lower speeds, especially on any camber around a sharp turn, or highways with an uneven surface. Read a lot of the reports on the internet here and elsewhere about Mazda 5 suspension problems. Did't expect it on a car that I had owned from new, less than 3 years old, but it gets driven a lot. Actually mostly on interstate roads for commutng and longer road trips. Took it into Mazda dealer where I had purchased the car. Over 36,000 mile warranty so didn't appear to be covered. Problem diagnosed as front suspension stablizer bushings. Replaced and problem gone away. I'm a little under $300 worse off as a result... ouch... but has been the only problem I've had to pay for on the car since owning. Power steering recall in 2010 was fixed at no cost by Mazda. Good value, very reliable and economical car for the money otherwise. You get what you pay for I guess. I don't know if the replacement bushings are a different spec if Mazda 5 has changed this now. It feels like new again with the front suspension feeling less harsh... we will see if i"m back at the dealer's again with the same problem in another 45,000 miles..... watch this space.

Bobbling noise felt thru floorboard of my mazda 5. Discovered it was a worn sway bar bushing, had them both replaced cost of repair $170 including parts.

Horrible clunking sound from left front (driver's side) suspension over minor pavement imperfections, gets louder over larger ones. Can actually feel the clunk through the floorboard! Most noticeable when car is cold, and during the first 15-20 minutes of driving. Completely disappears at freeway speeds. Right rear wheel has been making a similar sound for over a year and a half (since about 73,000 miles) so I'm fairly comfortable the front wheel won't fly off.. but because this vehicle was built to a cost and has almost zero floor padding or sound deadening, you'd swear it was about to! Have not been to a mechanic yet.. will post again once I do.

Clunking sound from driver side front suspension area. Only during first 5 to 10 minutes of driving. Dependent on road and speed. From home it always happens from work it never happens.
2008 Mazda Mazda5 174,000 mi,
4 time replacing these bushings. Totally ridiculous!
2010 Mazda Mazda5 53,000 mi,
It started to have noise from front specially in the morning when the car is cool ; after 15- 20 minutes driving , the noise is gone. Sometimes it doesn't appear even in the morning , checked the google seems to be sway bushing bar need to be replaced. I have extended warranty until 8 years/100K ; but dealer keeps saying my car's condition is excellent and it's common....I doubt they don;t want to go through extended warranty claim procedure. If it's only about $100 around repair , i would pay by myself
