Wishbone Bushes

[Maxx]

Hi all, So I've got a knocking from the passenger side front wheel area, it bangs when hitting a pot-hole or under sharp braking and also the car shakes side-to-side under heavy load.

I'm guessing by doing some research on here that it's most likely p bushes? Would it be worth replacing the wishbone as a whole or will some new bushes be adequate for now?

Thanks
