Hwo to fix this sound?

Does anyone know what makes this dull sound when I turn the steering wheel left or right, it's irrelevant... The mechanic told me that the shock absorber salts were the problem and we replaced them, but the sound only changed, but it's still there. Before, the sound was much duller and you could hear it a lot, now it is somehow louder but more specific, I don't even know how to explain it myself, it seems to me that the shock absorber salts were for replacement, but it seems that something else is causing a problem, who knows, let me know . I've seen videos on Youtube where people open a piece of plastic above the brake and clutch pedals and there is a half shaft and on that half shaft coupling they spray WD 40 spray and this is not heard, what do you think?
