After I checked and tightened center shaft bolts, the steering knock was reduced but not enough. I went and ordered the power steering shaft damper and today I successfully swapped the new one. It has not been easy, especially reinstalling all the components, being alone.

The old one wasn't that bad and not a lot of green pieces inside the case, despite a lot of videos I saw online with this problem.

I can confirm I resolved the issue.

I ordered the original one from AMAYAMA (45254-28040); it doesn't come with the little center "star shaped" spacer, but the old one was like new.

Edit: Italy, 160000km Edit2: this is the power steering shaft damper
