Low hum, or thump

[jltcet]

So been doing alot if trying to figuring out of why my 2004 out back makes a low hum, or a thump (very low) it gets louder turning to the left, less so to the right, and going stright is less noticable but still there. Just 2 months ago I replaced the hubs, bearings, calipers, and breaks, and rotors. I'm not finding any answers. I mean could the bearing in the left front be going out again. I mean that quick. Any help would be great. I dont think it's the clicking sound of CV joints make. But I guess it could be.

Thanks
