Strange unresolved noise

[wrebwen]

My CLK230 suddenly developed a loud whine from the front passenger side, it was taken to the Mercedes dealer as I suspected a wheel bearing. Nothing was found and the tyres are OK and I have also had the tracking checked which was OK. The noise is still there and the dealer cannot give me a reason for it despite having paid him over 350 euros ( I live in Portugal) The noise increases with an increase in speed - any suggestions as to the cause or anyone having experiencing similar would be appreciated. The car has covered 136KM and apart from the noise drives and handles perfectly??

Hello by jacking the front of the car you can feel if a wheel bearing is faulty, when tuning the wheel round you will feel the rollers if they are worn damaged, it will feel like a mild vibration feeling,,compare this with the other side and you will feel the difference.

Wheel bearing start humming on a smooth road from around 25 MPH and stay up to the max speed. By opening the window and leaning your head out they can be heard

Check there isnt a stone trapped in the caliper, I had this on an old spitfire made hell of a noise.
