Rear suspension/struts going bad?

Okay so im pretty mad about my '92 grand prix right now. Last weekend had to replace a brake rotor and caliper and now im getting noises from the rear. It happens on bumps of any kind small or big it sounds like its clunking like the back shocks arent working but the car is sitting at the right height and when i go to the back and push down the shocks seem to work but when i do push down i hear a click from the right side.

I checked my spare tire and jack those werent the culprit what could it be i hope its not expensive im freshly into college and cant take it anymore lol.

Well i found the noise the rubber boot thats on the strut above the tire was loose and the ring that holds it up was banging around.
