Clonking / Knocking going over bumps
HI, I have a 2007 231 6 speed Manual UK RX8. I have a clonking noise when I drive over bumps with the left wheel (i.e man hole covers) and rough surfaces but bigger bumps and general dips in the road don't do it. I have attached a recording which I made from inside the car as the noise seems to travel though the steering wheel and you can also feel it in the wheel.
I own a garage so I have had this car in the air on our lifts to check the steering and suspension and I have got to say I cannot find anything wrong. All bushes are fine and there are no loose bolts.
SO guys i'm stuck, I dont really want to take my car into the dealer as I cant see what else different they can do that I havent already.
I must also point out that this car has only done 5,940 miles so I doubt anything is worn.
Any ideas?

the torque on the front sway bar end-links?
or possibly this...

Thank you for your post, I hadn't seen this Mazda bulletin.
I'm afraid it's not the end-links as I removed them and drove the car a short distance and it still did it even when they were disconnected

Could by any chance it be the shock absorbers? Would I feel it through the steering wheel?? I have checked the steering rack mounts and they are perfect
No tools left under the bonnet as the car has hardly had any work done other than a couple of oil changes

I'd try retighten everthing suspension wise. How about the tower bar, and all the nuts that holds all the shocks, I remember mine would make a popping sound when I twist the chassis turning in to a steep hill.( you know how one wheel would start climbing the hill before the other wheel )

I will give that a try and let you know. It is booked in with the dealer for the 29th September but I would like to find the problem myself in the mean time
I had to look up what a tower bar is. I think in the UK we call it a Strut Brace

Last time this happened to me the dealer had left 3 loose bolts on my suspension, and the noise was very similar to yours, however mines were on the left rear side of the car. I also thought it was coming from the front of the car until I had some1 seat back there. you might want to check the rear.

Its definitely coming from the front as I have people sit in the back to verify this
With regards to the Sway Bar I've checked all the bolts on it and they are all tight.

i had the same problem and it came to be the bushings on both sides after greasing these bushings the noise went away.they only made a sound when going over speed bumps and slight ground height differences.tbecause of all the rain in the area they were preety dry. hope this helps!

Thank you for your reply at least I'm not alone with having this noise.
I disconnected the sway bar both side from the wishbone and the noise was still there

yea double check that nothing is loose under the hood and hitting up against it and check the strut mounts to b sure they are ok....not sure if u did that or not
