Low frequency noise.

[Thunderbird17]

Occasionally, not all the time, I hear a low moaning noise from underneath somewhere? It sounds like a dry rotationary joint.?
Only at low speed and only after about 5 mile into journey.
It will then disappear.?
It's not worsening...yet!
Any thoughts?
It's a 2012 C204 220 cdi

The way i got rid of my noise - was to buy 6 tins of spray silicone, and use them all up , on every rubber item i could find under the front and rear of my car . The rubber bushes dry out over time .. Doing above will lubricate the rubber and keep it supple, and squeak free. for years to come.

Not a squeak. A droneing low volume noise
