Mark is right. Both mine do that all the time when wet.

Thanks guys, I think it was just due to water splashing up. Now that I think about it, the same thing happend when I was driving an RSX. I pulled up to the same spot, went through a fairly large puddle, then heard a loud screech when I turned in. All the pulleys seem fine to me and I dont notice any appreciable leaks (except for the valve covers, though I can't see these things being linked). I guess i'll just add it to the list of quirks.

Yup. big puddle + cornering gets me a squeel as well.
very short time.

im glad to know im not the only one... lol

I get a little bit of a belt squeak after washing the engine; but that'* it.

You don't get massive amounts of rain like the others posting here do. Not only that, but the LeSabre may have different splash shields.

Thats a good point, how come the Bonnies don't have extensive shielding underneth?
