Front axle

Hello V8ler,
I've been listening from about a few kilometers. 70 KM/h from the front left humming sounds. At S Lines rides it gets stronger to the right while it disappears to the left. This morning there was also a strange creaking in slow driving and full right-hand steering. In the workshop (inspection + winter tires), on these symptoms addressed, I received the information the wheel bearing would probably not be and all axle cuffs are ok. So far so good but it is definitely something not ok. What's with it? Mark
