S10 Blazer, wheel bearing or joint shaft, who’s loud here?

Somehow I have a difficult to localize problem with my “small”. Noise, grim kind with vibrations up to the bottom plate of the driver from approx. 75 kmh to 120 kmh. Easy play in the wheel bearing left, not reusable since complete wheel stroke. In curves (BAB up and downs) the noise occurs only in left turns, so when the left wheel is relieved. When starting with fully beaten wheels, 4WD off, even at the left side long. With 4WD there is a very clear K Nack, but also only left long. Bumped up, relieved and turned by hand the front wheels can not provoke the noise. Tires on the left side of the inner shoulder have run out a bit more than normal. And now? Wheel bearing, receptive wheel stroke or drive shaft??
