Rear wheel clunking and squeeking noise does not happen all the time

Sounds like you have bad brake shoes, and either the wear sensor is dragging or the shoe rivets are cutting in to the drum. I would pull down and inspect. Also check your axle bearing while there. Remember if this side is worn so is the other side

I would pull the wheel off and take a look at the brakes. I don't know if you have drum brakes or disc If they are drum brakes they could have come up hooked and are rubbing and making the noise. also before you take off the wheel check that the lug nuts were tight and that the wheel was not loose. Hope this helps
