I’ve noticed lately that I have very loud rubbing noise coming from what seems to be rear passenger side. Only while driving and gets louder faster I go, with it being the loudest right around 70mph. It’s gotten worse here recently and I want to think it’s a bad bearing, I’m just not sure if the rear has a bearing only or if the hub and bearing are one piece. Couldn’t find any rear hub and bearing online. I was also reading that it could be the rear differential, but I’m just hoping it’s just the hub because I’ve changed one of those before with success on another vehicle.
