He said he changed it.

Maybe I dont know. But it's a brand new complete axel.

The other thing I can think of is something is going on inside the differential. Since it doesn't do it when it's jacked up, the only other suggestion would be if you have a friend at an oil change shop. They have those pits you drive over and a guy is inside the pit underneath the car. See if they're willing to let you or somebody drive it back and forth while somebody's under there listening. The problem with that is that there's the damn plate underneath that covers everything up. I don't recommend driving that car with that thing off, as it's also a structural part.

elac had me doing something like that, he said raise the rear of the car and put it in reverse and forward. I did it but the sound was not there doing that. Sometimes doing a left turn at low speed the clunking sound reappear but much less apparent, it seems to be related to something in the suspension.

Yeah, it's definitely something that happens under load, so lifting it up won't reproduce it. That's why I was suggesting an oil change place with one of those pits. That is, if you know someone who is willing to do it.

It could be a loose suspension or frame part that flexes under the change in load force. Or it could be something in the diff.

Ok now I understand ''the pit'' I just booked an appointment in a garage who has a pit. My appointment is July 30, that was the closest I could get. Good point piper6909.
