The washer wasn't tightened down onto anything, but couldn't just fall off because a bit of the broken bolt had stopped it from coming out on its own. It was plenty loose enough to rattle though... every time you hit the gas.

    I got the washer out of there and put a hose clamp on for the time being. That is not a nice area to gain access to from above, so once I get some time to get at it from underneath properly, I'll put a couple hose clamps on and make sure they're good and tight and well centred. In the meantime, it stopped the vibration noise. I went out for about a 30 mile drive and the car drove real nice.

    I'd say it was a big relief to get it sorted out, but I wasn't really all that thrilled about it when I finally tracked it down. I probably just muttered asshole to the car as I shut the light off in the garage and went inside.
