When wifey had the SSEi, she had mentioned of a rattle that started about 6 months ago or so. Wasn't a knock, more like a cable rattling under the left rear of the car. I crawled under a couple of times wiggling, tapping, and shaking anything possible. No luck. Then yesterday I decided to check the rear suspension crossmember mounting bolts. Checked the passenger side first, got about 1/4 to half turn. Hmmm. So I checked the driver side, the side with the noise. Wouldn't ya know, about 2 turns. I'm thinking the out of balance tires must have caused things to loosen up a bit. No more rattle, and the car seems to handle better. Now, to scrounge up the $$ for front lower control arms. I have a feeling I'm going to get the car back up to where it should be and she'* going to want it back. Also changed the trans fluid and filter today. Good excuse to go for a drive after.

Thats good. I HATE rattles, I cant sleep untill I find them.
After I got my stereo installed I had a new rattle (which made me very angry) but it was only the speaker thank god.

I'm glad you got that fixed! One time, my rear O2 sensor heat shield started rattling, and I didn't find the cause of the rattle for a while. When a friend of mine was crawling around under the car one day, he found one small wiggle and took off the shield. I don't have a rear O2 sensor anyway, so it all works out. No more rattle!
