79' 300D loud clunking/rattling from rear end on right turns

My 1979 300D started making a very loud and concerning metal on metal rattle about two days ago on my home. I didn't do anything to warrant it either, it just started around a 90 degree right turn at about 15 mph. Now, it makes the sound which comes equally from both sides every time I turn right at greater than 5 mph and progressively gets faster with speed. It is definitely a rotational sound too.
