Im at a loss, I’ve had this noise for about a year, and I can’t find the cause. there’s absolutely no play in the wheel, and the noise pops up only when driving, not when stationary.

Note : 4matic
I have changed :
Both struts and coils, (did not change coil seat and mount, could that be the problem?)
Lower ball joint left side
Sway bar links

upper ball joint, tie rods and everything feel tight. The noise almost sound like something is stretched past its max tension and snaps. I wonder if it could be bushings.

Any help is appreciated. Car has 185000 km.

 

Had a very similar issue on my 4matic. Ended up being my wheel bearing. I took the whole spindle off and had a shop press the new bearing in. I couldn't do it why my home press.

Check your front sway bar too. The bushings and sway bar come as one assembly and can't be replaced individually.

 

thank you very much for this info, did the bearing give any other sign of failing? I don’t have any noise at high speeds.

 

I originally believed it was my right side cv axel. When turning hard right it would clunk. After I had the cv axel disconnected from the spindle, I could rotate the hub by hand. The bearing was crunchy like the captain. I replaced it and the crunch was no more.

You can try removing the cv axel bolt and pull put the cv axel just enough to test the hub bearing.
