How long has the rear end oil been changed? Sounds like when you make a turn, you have the clutch plates in the locking rear end, slip and cause that chatter or noise you hear? The reason I say this is because you only mention it when turning right. And because you say, "sometimes" a lot, it doen't mean something is going south. If it was damaged, you would hear those noises constantly at most any speed. So the easiest thing and cheapest is to drop the rear end oil, put in the special clutch additive, (so you don't hear that chatter noise going around hard, sharp corners, and see if that went away?

a hard clank when shifting gears or takeoff would lead me to suspect U-joints

wheel bearings do make a whirring/shimmying sound, id suspect those if i were you

If you replace bearings, might as well replace U-joints too
