Front end rotating/grinding noise

hey all, long time forum browser, first time poster since i am at a loss of words.
i recently bought a 13 dcsb with 110k miles in february. took it to a shop for front end noise in my hometown of crown point IN. they decided my front diff and driver side wheel bearing and carrier bearing were all bad. replaced that 4k later and a new needle bearing was installed. after taking a long trip to buy my topper i noticed grease in my driver wheel well, cv boot torn and i’m guessing the shop tore it. so i replaced the driver side cv myself . developed a rotating humming sound on passenger side and thought it was the wheel bearing so i replaced that myself with help from youtube. the rotating humming noise is still either on the passenger side or right under the center console and i am now at a loss of words. the only thing i haven’t replaced front axle wise is the passenger cv and i get no clicking or skipping when i turn. any help or input would be greatly appreciated. my truck is 100% stock suspension wise as well.

 

Let’s start with stuff that is free to check.
Does the sound change at all in 4WD?
We are not necessarily looking for the noise to go away, but just a change in noise.
If so, it may be internal to the differential. There is a roller bearing in the passenger side.
It doesn’t typically fail, but it could cause a rumble when it fails.
That bearing is not like the one on the driver side.

I’d also check the fluid level in the front differential. Just because you can.
At this point, if it is low, the damage is done. But at least you’ll know.

 

it seems a little more quiet in 4wd but it’s definitely still there. i haven’t checked the fluid since i replaced my cv and added what i lost from the swap. i do know that the front diff doesn’t leak a drop at all since i was just under the truck yesterday reinstalling my running boards and double checking for leaks. but like i said above i had the front diff replaced so you would think they’d install a new needle bearing on the driver side and (if i’m correct) the ball bearing on the passenger side unless i got screwed..
