It downpoured today, and after it rained the car drove fine with no noise. I came up with a theory though. My front wheel bearings were replaced at 76,000 under a different owner, so possibly when the halfshaft was reconnected, it didnt go on perfectly straight and allowed grease to leak out of the CV boot. Over time all the grease came out and developed a squeak. The rain gave just enough lube to stop the squeak for a while.
Maybe this is totally off, I have no idea. Or maybe the rain just lubed up the rubber enought so it stopped making noise. LOL that sounds funny doesn't it?
