please help!!! clicking sound..

[Carnage]

So on my way home yesterday, i had to pull a u turn which i did rather abruptly and now when im driving along at 20kmh or more there is a clicking sound coming from what sounds like the rear right wheel or wheel well anyway. It kinda sounds like i have a stick in my spokes and gets louder and faster the faster i go. Does anyone know what this might be? I had a look and couldnt see any rocks or anything in my tyres or anything obviously loose but i havent had a chance to get under the car yet and have a proper look.
any ideas??

At a guess, it's something you've picked up in the tyre.

Does it sound like a metal to metal ping or tick coming from behind the seats?

If it does it could be a cracked PPF. Check out this thread - viewtopic.php?f=29&t=42534&hilit

from what i could hear it didnt sound very metalic, its not that harsh of a sound but very annoying and in the car seem quite loud.

got home last night with it clicking the whole way... My brother and i go for a drive to show him the sound and see if he can help identify where its coming from. Nothing, no sound. Get it home and jack it up to see if we can see any problems. The only thing we could find was that the sway bar bushing looks very warn and the bar its self looks like its sitting at an odd angle, didnt seem to me that this could have been the sound but maybe... My brother also noticed that my diff looks like it might be leaking some fluid or had been at one point but there isnt any grinding noise or anything so i dont know. Perhpas something was caught in the wheel well or tyre and has now fallen out, hopefully... but it looks like im going to have to do something with the swaybar anyway.
Thanks for your help guys, couldnt get the car higher enough to check the ppf, dont know what it was but its stopped so im happy for now...

Better check your oil level in the diff also and then get some new seals.
