Anyone familiar if there's anywhere I can test output voltage of the motor and see if it is in spec or perhaps failing to output required voltage?

I can’t find a test procedure/voltage spec for the steering motor in the service manual. Just about every other vehicle component has a test spec so I’m surprised I can’t find anything for the steering motor. The service manuals are floating around the forum if you want to locate them and have a go at searching for the spec, maybe you’ll have better luck.
According to the the manual, Techstream can be used to test for intermittent connection failures in the wiring, if you have access to Techstream.
If the problem is in the steering angle sensor you should have warning lights for abs, traction control, and stability control because those all rely on the steering angle sensor.
The power steering motor is under the dash, I can’t remember its exact orientation, so it’s possible it’s above the left knee area and that’s what you are hearing.
There’s a “common” issue with these cars having the internal rubber coupler fail in the steering motor. It’s generally discussed as a “rattle fix” and I haven’t had the problem with my car, so I haven’t had the motor apart to know if the rattle could progress into failure, but it might be worth investigating.
