clunk in rear suspension

It seems to have gotten a little worse nowdays. every time in a sharp corner when the rear moves in or out you hear a clunk or click. the same happens very often when getting out of the car but only rarely when getting in.
here are some videos i try to make. https://streamable.com/cu9p0 https://streamable.com/68yql

What could it be and is it urgent fix or not?

Do you have a sway bar and are the mounts rusted?

sounds like side to side play on a wheel bearing. See if the noise changes or goes away if you engage the parking brake.

thanks.

I tested with e brake and still does the sound. Didnt see a swaybar on the rear. Also doesnt make the noise when i tug on the wheel side to side. only when i lift the car from the wheel arch.
I will lift the rear and check the bearing soon.

Checked the top bushing, cant see or feel any movement in there when i move the car. the wheel bearings also have no play or sound and they both spin for minutes if you turn the wheel.

Try to isolate the side the noise its coming from by lifting just one wheel off the ground and repeating your jounce test.

Is the exhaust pipe hitting a coil spring, or is there is anything loose shifting around in the spare tire? Does opening and leaving the hatch door open make a difference?

Im really kind of puzzled what it can be. i dont see or feel anything loose. and as for pulling it up even a very light pull is enough to make it sound. less than half an inch of movement is more than enough. No exhaust touching either. :hmm

handling is not affected eighter and there is nothing loose in the spare tire area.

keep looking. I had an Opel years ago with a rattle i could not find. I finally took it to a dealer and 2 mechanics took it out over a bumpy road with one in guy riding inside the trunk. it turned out to be a worn bushing that was tight at rest and only rattled in a certain position.

http://geometroforum.com/topic/8202703/1/ and under 'Brake fluid change to DOT4', in the picture of the brake drum isn't the bearing seal supposed to be towards the outside?

Yep. Put some wd40 onto the lower part of the spring and no more clunk. Only now it scrapes. Well at least i know where the sound comes from. :lol

Put wd40 on both sides and one test drive later the noise is gone. no scrape noise as well.

Well done LesCrapp, you win this round.

Swift-guy: You're going to need something more substantial on there, WD-40 is NOT oil and is designed to mix with water. It'll be gone in a week.
