front passenger side wheel bearing

I just want to know if my diagnosis is correct, I keep getting this rough almost grind like feel from the from the front passenger side wheel, I keep thinking that it is a wheel bearing, just want to make sure that I am correct.

 

Hoping not. I need to check mine out too before they get that bad. Can we even repack them or are they some sealed maintenancelessness bullshit like u-joints and ball joints are on the prerunners?

 

well you can buy one for 30 bucks off of rockauto.com, repacking to my knowledge is not possible on the tacoma, but I have been wanting to find the diagram to change it because I deff think that it is a wheel bearing
