SLK/R170: noise from differential
I only hear the noise when I am driving between 45 and 35 mph, and I take my foot off the accelerator (coasting). Once I accelerate the noise stops, or my speed raises/falls above/below 45-35 mph the noise stops.
I place the vehicle running on a lift and observed a vibration coming from the area were the drive shaft enters the differential at the above speeds.
Anyone experience a similar problem?
