i just installed new struts in my rears and now from the right rear, i hear a rattling noise going at slow speeds (car isnt too noisy). i had my dad drive around and when i sat on the drivers side, i could hear it but when i sat on the passengers side, it was gone. so im assuming that my 150 lbs butt pushed something down...

i check and double checked everything over and over, it was all torqued to spec...what could it be now? and ideas would be great. thanks!

 

When i heard a noise I had my frined ride in the trunk with the trunk closed while I drive over bumps. I know this sounds funny, but it will give you a better chance to pinpoint the rattle.
