I have hum in my car

Sometimes it is not always at speeds like 100km while going on the road. When I turn the steering wheel slightly to the left, the hum of the left front wheel feels high from there. If I flip a little more or turn right, it will be cut off instantly. I asked one of the master, said from the ball. No tearing, explosion in axle protection. Nor does it maneuver where I am. The hydraulic level is also normal. I had a ball problem with another vehicle before, they were on the back wheel and it was coming all the time What do you think could be the problem? Also, this sound does not come out every time and does occasionally. 2 times at 500 km.
