Funny suspension noise

[nomead]

I had this weird noise on the car when making a sharp turn to the right. Something in the back made a noise like there was an empty soda can rattling around somewhere. I checked the boot and interiour, nothing loose lying around. Next I jacked the car up and looked at various suspension parts and mounting points. No problems found there... Starting to get really puzzled now. But I just continued driving, just to see if it got worse and it didn't. So a week or two passed, with the noise going nowhere.

I was going to write a message here tonight, asking for help to identify the source of the problem, but earlier today, I stumbled upon it on my own. I had some extra time, and I decided to look underneath the rear seat cushions. And in addition to the ordinary accumulated crap, there was a golf ball under the seat! It even had enough room to rattle around, because on both sides under the seat, near the door, there's this maybe 10x10 cm empty space. I threw the bloody thing away, and now I can chuck the car in any direction with no extra sounds. Good thing, because now we're starting to have ice on the ground, finally I can have some fun with the car
