Check rear sway bar endlinks and bushings. If they are worn out, replace them. You might also check your rear exhaust hangers. They've been known to clunk in the same fashion as well.

This is exactly what I did when I had this problem. I ended up replacing the sway bar endlinks and bushings and the problem went away...

If it's pretty much just a low frequency 'squeak' then it's the rear spring isolators. The rubber isolator at the top of the spring is notorious for squeaking when the weather turns cold. Anywhere from 50 degrees down I'd say.
You can either accept it as normal, or if you must fix it I'd say there are 2 things to try. 1) remove them and do the 'heater hose mod'. or 2) spray some white lithium grease or similar up there.
Even with #2, to do it right you'll want to unbolt your rear end and drop it far enough to get the spring unloaded. I am not sure if the sound is the spring on the rubber, or the rubber on the body. I think it's the rubber on the body, so you have to get the grease above the isolator.

It's also known that they will cause excessive binding in about any bushing area, but for the rear LCA's and PHB, these areas are critical to the manoeuvering of the rear axle. If you are a dedicated drag racer, then yes, the bind is very useful, but for the street, AX and/or RR, they're counterproductive for handling.
For these reasons, many choose to stick with stock stamped LCA's then upgrade with improved bushings in the rear.
Just some FYI
