Hello,

If you hear a constant humming noise and it changes as you speed up and slow down. It is likely due to bad wheel bearing. Over time the seal around the bearing will go bad and allow dirt and debris to enter the system. When what happens it will typically make noise.
On this vehicle the wheel bearing is part of the wheel hub assembly.

This task can be performed using basic hand tools. You will have to jack the vehicle up and support it on jack stands in order to perform this task.

Here is a helpful guide:

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
