Hi! I have a -73 240z with a clunk in the rear left. I figured it was the U-joints since I could turn the half shaft a little. However, the U-joints in the half shaft turned out to be perfectly fine. It is instead freely moving further in, against the diff connection AND out at the hub axle connection. It is like the half shaft is stiff but the ends allow for some play? As you can see in the videos below. Does anyone have a clue what could be the issue? Worn hub axle (but still shouldn't move in at the diff correct?). I've read a lot about rear end clunks, doesn't seem to be that unusual .
