When i drive over a little or big bump on the road. i hear this annoying clunking noises. I believe it from the rear suspension/strut. Its sooooooo

annoying sitting in the rear seats hearing that noise.
I looked at the sway bar bushing earlier but it looked fine and normal. can someone post a bad and good bushing? and how do I change bushings?
Do you guy experience this? do you know what causing the noise? and how do i fix it?
Thanks!
and car has 120,XXX mileage, (the car is my avatar) and it never had any accidents. so im guessing its a wear and tear thing. but how do i fix it?
