I have a strange low pitched noise coming from my na 93 850 5 spd with 163k. Remember blowing over the top of an empty pop bottle? Sounds like that. I think it comes from the back.
It is intermittent. Seems worse on a windy day, but not always.
It has a trailer hitch (makes noise w/hitch in place or not. Car is missing the end cap from the back of the drivers side rail.
Also seems to be a bit louder w/right turns, again--not always.
Also seems to have a sticky parking brake. Sometimes the right rear rotor/brake feels hotter. Sometimes not.
Car runs fine, the noise does not hurt performance. However, it has me a tad concerned and a bunch puzzled.
Thanks
Tom
