Strange sounds from the back of the car
Hello. I'm from Europe, and I'm not a native speaker, so sorry if I word something out wrong...
I got a 2009 GLK 220 4matic. A couple of weeks ago these strange noises appeared from the back end of the car when turning left or right. I don't know how to best describe it, it's not a sound of metal surfaces grinding on one another, but rather a frequent dull sound of something popping or maybe extending (the sounds is like hitting a rubber tire with a wrench or something like that). It can be heard clearly when turning to the left or right at low speed (when parking, at intersections etc.). And I guess the most important part is that the more I turn the wheel (to the left or right), the sound becomes more frequent (the most frequent when I turn it all the way). It can not be heard at all when driving straight or turning slightly.
I don't know if it's maybe the tires, the rear differential or something else.
Any information is appreciated.
I'll try to post a link to a video. The sound at 00:08 to 00:12 and after 00:18.

Make sure your lug bolts are all tight...
It sounds a lot like rubbing, more than some of the more usual noises (like bearings, axles, or a bad differential).
Really loose exhaust hangers can cause similar noises, when the exhaust system contacts the body - see if you can easily move the rear of the exhaust system left and right, enough to "touch something".

The one thing I'm curious about ... what was the mileage (even approximate is fine) that the mounts were changed ??

Here in Europe, you can never be sure about the mileage if you buy a used car. Officially, it's 230.000 km, but i'm guessing it's more like somewhere around 300.000 km, or 180.000 miles.
