Hey Brian, I guess you could try that method (i have done it myself many years ago) but my advice would be to buy or borrow one of these. It's called a Chassis Ear and I have had this tool for going on twenty + years and not only has it saved me ton's of time and misdiagnosis by pinpointing a noise location but has also proven me WRONG in my initial opinion of many different types of noises.
I wont even go in to how many squeaks, rattle's' clunk's, growl's, moan's, OK you get the picture. I have used it on every type of vehicle you can imagine. I used it on a O-540 Lycoming airboat engine to pinpoint the exact cylinder that was making noise. Have you ever heard how loud an airboat is ?
The last time i used it on a neighbor's F350 superduty he initially stopped by one evening and asked if i would go for a ride and listen to this noise, it was obvious as soon as we got up a little speed it was a frt wheel brg. and i gave it the old swerve technique left to right to load and unload the brgs and listen to the change in sound.
I told him he had a bad R.F brg. and he asked me if i would take care of it and being the good neighbor i am i said yes no problem. Having been down this road before i said let me throw the chassis ear on it before i start tearing in to it and guess what, it was not the brg i said it was it was the L.S.
I have to warn you though if you use this tool you will hear things you have never heard and wonder how some of the components you listen too ( especially Engine and transmissions) Dont blow up or explode LOL.
It has 4 sensors and 4 channels and you can switch back and forth on the fly and listen to any component via the speaker or the earbuds. I have always found the speaker kinda unreliable due to cabin noise but the earbuds work great to block out everything but the sensor noise. Compared to what you have spent so far on this car i think you would be very happy with this tool ( not expensive) and find many use's for it, not just automotive. This tool will not fix your noise but you should be able to pinpoint where it is coming from.
