Clunking in left rear

I have a '91 Dynasty, about 286,000kms (just in case you need it ;) ). Last week I went in for my inspection and passed after a little body work, putting a new clamp on the muffler and fixing the right rear strut. HOwever since after having that done, I've had an annoying clunking noise in the left rear when I go over a bump (which is almost constantly on our horrible roads). I never had a problem before even when the muffler was loose but this is really annoying and almost seems to be getting louder or I may just be really sensitive to it, wondering what it is. Any ideas?

Mmmmmm.... body in the trunk?

Couldn't find one :D

I had my father go all underneath yesterday and he couldn't find anything that was loose or that could of been hitting (he knows more about cars than me, lol!). I think I'm going to call the guy who did the inspection and see what he thinks because it's really annoying.

dunno i got the same problem on my jeep

Well, $10 later, the sound is gone :D . My toddler was keeping me too busy to ask what was wrong, but it couldn't of been anything too bad.

ok cool so its a cheap fix
