I could use some help diagnosing what's wrong with my 2000 Yukon, 4wd, SLT. I just changed out my front left wheel bearing hub that took care of a bad grinding noise. Now I have a humming noise coming from the same wheel only when I turn left. There is no clicking noise coming from the CV joint and the humming noise show up at speeds of 25+. It sounds exactly like snow tires humming on the highway, but only when I turn left and it wasn't there prior to changing the wheel bearing.
