This is weird to me, when I take corners going right I can hear a slight sraping noise coming from the left rear of the car.
I have inspected all that I could and did not see anything apparently bad. I have a 1988, and nothing has been done to the suspension.
PS You can't hear it when you make a right hand turn from a stop, it has to be going around a bend/turn while driving.

hmmm, if you jack that corner up can you see if the wheel moves in an unnatural way?

wheel bearing or maybe the washer is bad

Check your parking brake system....or maybe a "bad" rear shock on that side? Also check the sway bar and transverse spring bushings.....good luck, don't worry you will find the problem. It just takes a little time and some $$$$$$.

Grease the hubs! I had the same problem on mine, I took the hub out and there was zero grease on it. I greased it up and she never made a noise again.

And if my diagnoisis is correct, I would reccomend changing both hubs not long after because if one is bad, the other is probably bad. Also, if they're badly damaged they might give out on you while you're driving.
