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.

Could it be a ball joint? It's a 2002, so after 23 years, maybe the grease in the boot of a ball joint has dried out, and it begins to make a clunking sound, metal on metal, like mine. Anyone has experience that?

I haven't experienced ball joints making that kind of noise when they go bad. But then again, as a DIY'er I've probably have changed less than ten of them on difference cars. Not ruling that out, though. Your appointment was yesterday. Didn't they find anything?

The mechanic was not able to find the clunking sound. He said he does not have expérience with european cars. I booked another appointement with an european specialist. His shop is 1 hour and a half from me. The date is august 5, at 10:00 , thank you for the follow up.

That's too bad. Were they able to replicate the noise, at least?
How well does your e-brake hold? Have you tried going into reverse with the e-brake on, just to put load on it, but not to actually move? If it still makes the noise, you can rule out anything rotational, and concentrate on frame/suspension.
What could be happening is that the load shift going into reverse is causing some movement somewhere. It could be a loose subframe, suspension link, or even a crack in the frame.

I have done the test with e-brake it does not replicate the clunking sound.When doing a left turn sometimes it does the clunking sound. If i’m parked on small slope I unlock the e-brake without the engine running and the clunking sound reappear when the car go back.

I did not drain the transmission oil just add a half a litter to get it at the proprer level.

Went to another garage the mechanic said all the rubber bushing and ball joint are good. Nobody is able to find this clunking sound.
