Hi I have a 04 Auto Base. Since last week my car has this really annoying squeaking noise coming from the trunk. This noise would only occure on bumpy roads. If its a straight very smooth road I would not hear a thing. To be exact its coming from the driver side rear. I tore all of the carpet and the foam that covers the spare wheel and had my brother lie down as I go up and down bumpy roads. He had determined that the noise to be exact is coming from the driver side rear. I also had him stay in the middle of the street as I drive towards and away from him. He said he can easily hear it from the outside. I searched and read about 5 threads about this same problem but everyone that had that problem had aftermarket suspension. Im pretty much stock except for a aftermarket exhaust and aftermarket wheels. Ive had those two items for a year and a half for the exhaust and 3 months for the wheels. Would could be the problem? Would it be the bushings as I hear in most of the threads related to my problem? Im about to lower my car on tein s tech springs would that fix anything???
