So here's my one of many issues with my jeep right now. Thankfully my other issues are self explanatory so far. The one issue I am having and have no idea whats causing it is this terrible humming noise in the front end. More specifically from the passenger side. Wheel bearing is good, CV good, intermediate good everything is good. Yet there is still this continuous hum while i'm driving. It starts around 30mph and increases with speed and will stop when I cut the wheel to the right while turning or going on/off a highway ramp. Any chance this could be differential related? Any other suggestions? Getting really close to having to call a local garage but trying to avoid paying those labor costs.

Power steering bearing?

My guess is driverside hub since it cuts out after you turn right. And just because it seems good doesn't mean it is. Both of my bearings seemed good from tests and sounded like they were about to fall off. Changed out both and the noise was gone. Once I got them off you could definitely tell they were bad.

X2.. I had the same problem. I had a loud growl that was not tire related and I replaced the wheel hub and it was nice and quiet other than the diesel noise.
