I just replaced one on a 2014 S class with 25k miles. It happens, they can fail.
To make a long story short, the car remained at the dealer for 5 full weeks. They still don't know what causes the noise, but somehow it has miraculously stopped sounding. It must be haunted. . .








I was able to visually inspect the driver's side suspension rubbers and nothing seemed torn or falling apart. Sprayed ball joints and control arm bushings with Silicon WD40. The car still made the same noise while jacking it up and dropping it during wheel stud install. Took the whip out for a long test drive after the stud project. Slowly the sound dissipated. By the time I came back home, there was very minimal noise/negligible. If the noise comes back full force, oh wells... I will take it to a shop. $7 for a can of WD40 was well worth a try
