My fix of simply wedging a credit card under the brace worked great for about 800 miles. I drive about 800 miles a week. Over the next 1600 or so its still pretty much fixed.
It does not disappear 100% but its waaaay better. It was insane before that.
If it does show up, it's gone after about two minutes of driving. Before it would up to twenty minutes. It's also more muted, and if it makes a full rattle, which is rare, it's shorter and the vibrations are different than before the credit card shim.
I'm ok with he way it is now, and consider my fix about good enough for now. It's not really often any worse in the last two weeks. The sound was gone for a week though, and even though it is still quite good, something has changed.
