My ML320 has started to make a humming/friction noise when driving and gets louder as you go faster and goes away when cornering to the left. When I straighten out or turn right it comes back. The sound can be felt through the steering wheel.

On a hill when put in neutral it makes the noise when coasting and gets louder when going faster.

I have checked each wheel for play and bad wheel bearings but cannot detect any noise or movement in the wheels?

I have checked the drive shaft center bearing and there again I cannot find any play or noise?

Anyone have any ideas? I appreciate your help.

"Drive" it on the lift and listen with stethoscope. Here is my ML350 center support whine.

Thanks for the video. I will give it a try.

Sounds like a wheel bearing if it goes away when you corner.

Thats what I thought but just cannot find a fault by spinning and moving wheel for any movement. Might have to get a mechanic to check it for me?
