after driving for 40-50 minutes (no highway) in traffic, the car will make random creeking noises from the rear. They can happen just about any time, turning straight, smooth or bumby road. Once it starts I can reproduce the noise by rolling and hitting the breaks for a sudden stop.
The longer I drive it after that point the more frequent the noises become.

Any ideas?

 

rear pillowball mounts?

 

Sounds like pillowballs since when I test drove a car back when I was buying, it made the clunking sound every time I stopped too.
Heres a little help if thats the case with the pillowballs;

yup, sounds like the pillowballs need to be replaced. Same thing happen on my first FD.

 

i just replaced mine 2 weeks ago and when they started to go bad they creaked and then got worse and started clunking when i hit bumps, hit the brakes, or let the engine slow me down. Call Ray Crowe at Malloy mazda he got me everything i needed for 430 shipped.

 

well worth replacing all 8 on the rear,Makes one hell of a difference

 

Call Ray and don't forget to get the seals. Research your installation project before you begin.

later

 

checks the rear shocks bolts (romve the covers from inside the car) one of the bolts broke of on one of my shocks! more of a banging noise though

 

Thanks guys, I'll source them from a more local supplier as I'm on the other side of the world
