annoying "squeeking"

I have a '99 SE. I hear this annoying squeeking coming from the rear whenever I hit a bump. I had new tires and struts put on about a year ago. I thought that solved the problem ( I needed tires anyway) but the squeeking has come back. If I push the rear-end down real hard when she's in park, I also hear the squeeking. Seems to be coming from the rear strut area. Any idea ? I'm hoping it just needs some greese or WD40 or something. Thanks

There should be grease fittings on the rear wheel ball joints. It fixed my 95.
