What is a bushing (1998 c230 mercedes benz)

While having some front end body work done on my c230 the shop sent the car over to the mb service to check the front end. Of course they stated the alighnment was fine but the car needed “bushings” cost around $800.00.

Just how much should that job cost and where do I best go to have this checked. I do notd tdrust anyh car dealer for any work like that.
