Default 2015 Suburban A/C Heater Fan loud on high

When I turn on the fan to blow air, at a high setting the fan is loud—just started recently.
Not sure what I need to do. I can use tools, but I don't know where to start. The fan, or other aspects of the fan, that could be causing the problem.
Your help is appreciated.

the blower motor is probably wearing out. It's accessed from under the hood on the passenger side.
