1- simple camber adjustment- easiest to fix with a 2' level
2- worn bushings- look at the strut rods
3- worn spring
4- worn differential axle faces- one of the common causes
5-loose outer wheel bearings - although they would be loose to show this

grab tthe tops of the tires and rock them in and out. IF its a serious problem they will move alot and you will hear clunking. The possiblities that GTR listed you will be able to see. You will need to use your phone and video the rear end while you rock it or get a partner so you can lay under there and watch. anything loose will make a clunk and you will be able to see it move. IF nothing moves then its just the adjustment
Do you have adjustable strut rods or the stock ones. I have the adjustable so I can easily adjust that angle. They should be angled in a small amount so you get good traction in a turn if they are verticle you will be slidding around your turns....alot. Its fun but only if you expect it and like drifting.

That is adjustable with the rods off the bottom of the differential. That adjustment will move the lower half of the wheel inward as the top moves outward; so make certain the lower-inside of the tire still has plenty of clearance when you adjust it.
AND... for a few days/weeks prior to making the adjustment, daily spray a penetrating oil like PB Blaster (not WD40) around the camber adjustment bolts and nuts at the differential end to give it time to work itself into the nooks and crannies. These adjustment point bolts can get pretty stubborn to rotate like they should and need all the help you can give them.
