I'd venture a guess that you need to replace a rear "camber link"
(AKA "upper control arm"). They can be difficult to diagnose by just
pulling on the wheel, yet can still cause a racket over rough
terrain. You need to have the wheel raised, then grasp the bottom of
the tire with both hands and tug vigorously upwards--hard as you can.
Hear a slight "thunk"? That amount of wear is all it takes to create
some banging over bumps--especially if the rear is loaded.
At 140K miles, you're due.
P.S. I replaced the driver side rear link on my car two weeks ago (at 160K)
