Rear Sway Bar Bushings And "the Clunk"

[speedshift]

I have a 94 ES. 75k miles

I've read throughout this board that the bushings are a good suspect for the rear clunking noise that people hear on mid 90's ES's. I took a visual look at them today and don't notice cracking or anything.. I grabbed onto the bar and moved it back and forth with good force to try to make the noise I'm hearing without any luck. But I guess I don't really know for sure how to tell if these are bad.. ideas?

hmmm mine looked ok when i checked, but i moved them around and it replicated the noise, so i changed them and the sound was gone....change them anyway its only $26 form lexus....
