Alright, so about a week ago I replaced Both front wheel bearings (Entire Hub assembly) along with brand new axles, break pads, and driver caliper, Steering stabilizer. Basically The whole front end is brand new. When driving I get a pretty noticeable vibration/somewhat of a grinding/humming noise from under my feet pretty much. So I checked my front differential to see if the gears were the problem. Today I changed my front differential fluid, and the gears looked great! But i'm still getting a pretty noticeable noise.

I took it to a garage because I was pretty much stumped with it, and they said it could be the, "Axle Bearings" (?) Could this be the issue..?

I tried looking up videos on them but haven't found anything. Could someone point me in the right direction, or even suggest it could be something completely different. If something like this has been posted before please link me to that thread! Thanks!

The axle bearings are the hubs you just replaced. There are axle seals, which should have been replaced when you did the hub and axle install. While this was all apart the front axle u-joints should have been replaced as well. Any one of these items could be the culprit.

Those all have been replaced with brand new parts except for the Axle Seals.

I think I may have found out the issue. The 4WD kept flickering when I was going at high speeds, so I took about 3 minutes to pretty much perfectly set it in 2 wheel drive lol. It didn't make the noise but i'll drive some more today and see if that actually did it.
