If you google just silemblock you can see photos of where this part may be part of the wheel suspension (or shock absorber) or the engine (air conditioner).

Welcome to the forum!
I go for silent block too. Originally it was a proprietary name (perhaps introduced by Daimler in England - not certain) now it's almost any sort of bonded rubber to metal (usually steel) bush. Yours could be in various places in the suspension - for example at the end of a shock absorber, mounting an anti-roll bar etc.
It's "silent block". They have replaced a metal shielded rubber bushing or something like that. I guess is something in the suspension, isn't it?
