good morning my name is ***** ***** I will assist

since you replaced the wheel bearings, which is the most common failure, your bearing noise may be coming from the front differential. have you changed the fluid in the diff as required and checked it as well??

I would remove the cover and check for any metal shavings from a failed bearing. it sounds like it is coming from the front differential.
