Noise under car
Ok , so i have a noise under my car , i know there are some threads on this , but everyone is different , i am just looking for ideas since i am flat out desperate now
I have changet , all bushings (superpro) plus pillowballs , just got a brand new set of stance coil overs
when i do a low speed pull up , better said , move the car (not a long distance , in my driveway for instance ) and brake suddenly i hear like a clunk sound
seems to be coming from the front and back
Its not the trunk i already checked that , i dont have anything in the trunk or bins in the back of my seat
I have NO idea anymore what this could be and its starting to get extremely frustrating
Anybody have any ideas ?

If not ball-joints, there's this. Even with the Super-pro you might have this movement....
Dull thud/clunk from the front end when braking at low speeds? I had the problem described below and also did the fix as described. It's cured it for 6 or 7 years now. If it is your issue, it wouldn't surprise me if your mechanic missed it. You really had to look close to see evidence of this "fore and aft movement" on my car. There was just a little shine on the inside of the chassis mounting points even though (at the time of inspection), the upper 'A' arm bushing wasn't touching it.......

I had a clunk in my front suspension since I bought the car. I had it checked and found that the bushings in the upper A arm allowed excessive movement. I was told that it wasn't a safety problem, but I worried about handling due to changing steering geometry.
The pivot point to this bushing is actually a metal "tube". The bushing limits noise and softens the road harshness (mines an R1 so it doesn't feel like it softens it much).
I wanted urethane bushings, but couldn't find anyone who made them. I watched the movement (on a rack, not on the road! I'm not insane!) and realized that if I could limit the fore and aft motion I could live with these bushings until such time as I could find urethane. (By the way I was warned by 3 Mazda shops against replacing just the bushings. They wanted me to replace the whole A arm because they had heard of several people bending the A arm when the bushing was pressed in place.)
I took the upper arm off and found that the inner metal tube had a diameter of approximately .625" and the OD of the bushing was 2". I made a trip to my local C&S Hardware store and found out that a standard 3/4" washer had a hole diameter of .75" and an OD of 2". I spent 80 cents and bought 2. It was simplicity itself. It took me about 15 minutes to install them as "spacers" on the back side of the rubber part of the bushings. It does not interfere in any way with the metal inner tube. They fit as if they were made for that purpose. They did not cause any binding in the assembly as the assembly tightens down to the inner metal tube, not the rubber bushing. I still have the flex and shock dampening, BUT NOW I AM NOT ASHAMED TO DRIVE MY CAR! The noise is completely stopped and it did not change my front end alignment.

I recently replaced all my bushings and pillow ***** aswell and had a clunk when moving the car. Turns out it was my midpipe catching the driveshaft. According to Speed 1 the this is a common problem with one of the common midpipes on the market (bends are wrong or something). Anyway, its something to check and something I wouldve totally bypassed and wouldve been on an endless chase for something in my suspension.

FIXED
So the clunk noise got more persistent. ,i got pissed and decided i would tear everything apart until i find it
After careful checking ,i noticed my front bushings (controle arms) looked strange ,and upon better inspection it seemed that in my rush didn't change them (i had them ,they were included in the kit) i just forgot to change them
The old ones seemed ok but when pressed out one of them had a nasty tear ,...
Changed them ,did an alignment and the car hasn't run this smooth since i bought her back in 97
Feels amazing ,...really really nice and smooth and NO noises whatsoever
Just goes to show ,your head can play tricks on you ,it pays to double check your own work
Thanks. For all the inputs guys

This topic has been covered quite a few times. I understand you are a new member. I'd like to encourage you to search a bit more and you will find the answers to all of your questions.
Should be noted...these cars are money pits...when someone is worried about something being too expensive...I get worried for them. =)
