Hi! Welcome to JustAnswer. I'm Ron Z and I'll be helping you with your question today.

Does the sound tend to change pitch/loudness the faster/slower the vehicle goes?

Does the sound tend to ease up when you turn one way or get louder when you turn the other way?

Ok, great. This is the tell-tale sign of a worn Wheel Bearing. On this vehicle, the bearing is built into and part of the Wheel Hub Assembly (makes it much easier for replacement this way). The hub and bearing sell for around $230 and the Labor Time Guide calls for 1.3 hours to complete the job. Labor rates vary from shop to shop, so what you pay for labor will effect the bot***** *****ne. For a job of this type, a "fair" labor rate can be anywhere from $85-$125 per hour.

Hi! I noticed this thread was still open and you did not leave a rating , so I wanted to check in and see if there was anything else I could do for you on this issue? Did you have any other questions? Was there something I missed that you wanted addressed?

The humming sound stops as I stop when I'm turning corners it stops only when I'm driving it just started also I have big and small potholes in my yard

These are all symptoms of the worn wheel bearing as described above. Replacing the passenger's side wheel bearing/hub assembly will solve the problem.
