1997 Lumina....Squeak Over Bumps LOL

hi, whenever i go over a bump, i hear a squeak coming from the back end of the car......could it be the shocks? or what?.....it is quite loud, and continues to squeak as the car "bounces"......any help thanx!

You find it be sure to tell me....mine emits a loud metallic shriek from the rear over speedbumps and potholes...has been for several years now...can't find it visually, but I suspect it's at the top of the strut, a well-placed shot of WD-40 or silicone will make it stop for a while....
