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.

There's a knocking sound like something is loose in the suspension. The sound is especially noticeable going over a bump at low speed. The knocking sound first appeared in the front suspension, and I replaced a front stabilizer bar. The knocking sound has now appeared in front and back, and even seems to have come back in the place where it was first repaired. I have since learned that this is a common problem in the Mazda5.
A moderate to severe rattle at 20-35 mph on a bumpy road. Seems to come from passenger rear suspension
Recently had service, noticed afterwards there was a knocking in the rear drivers side. Thought it was all my tools etc at first, then gradually got worse, now going over a bump or swaying causes loud knocking and creaking and it has now spread to middle of car and is getting worse.
There is a rattling noise coming from the back of the car when ever I drive over rough roads or a bump in the road. I am taking it my mechanic next week.
Had been noticing it for a while, and when I checked my warranty, They were covered up till 60,000. Mileage on car? 60,100. Life sucks. Still needing replaced 20,000 miles later. Hopefully getting 'em done in Jan w/ tax check. Even on smooth roads, the front and rear wheels rattle like we're going over speed bumps.
Rattling in rear on bumpy road
constant and repeat, now I replace them in my parking lot
Loud noise when I go over any bumps
Rattle in rear suspension
I replaced struts and it may not have even been bad obviously this may of been the problem continued later to have the same problem.
It seemed a little better after replacing struts but was short live.
Tried greasing may of helped for short time
This has been a problem with my car since early on. Replaced the rear shocks and struts at 110,000. Still makes the sound. Will check the rear shocks and struts.
Only when driving slow over rough roads sounds like wheels are coming off. Mazda dealer said it was the rear sway bar bushings and links, replaced it. Same noise, returned and dealer replaced both rear shocks, seems to have fixed problem.
Every time we drive it it rattles and it squeaks
Replaced both front & rear sway bar bushings.
bouncy rear shock and noise like some thing loose with drive on street like driving a horses.
Squeking issue resolved short term with spray grease on the bushings until new ones are purchased.
Rattling from rear is either the rear shock dust cover vibrating on bumped or loose sway links.
