Lower Wishbone Bushes on 08 Passat est

Hi all. I have an 08 Passat TDI estate.I've had an advisory on last mot to get bushes replaced on front lower wishbones both NS and OS.

Some mechanic said the bushes can be replaced on the wishbones, another guy today said the bushes can't be replaced and I have to replace the whole lower Wishbone minus the ball joints.

Which is correct please?

Also if the job is done would tracking be counted as part of the rectification after installation of new wishbones or would that be an additional charge? I've been quoted £300 to replace the lower wishbones.  Many thanks. Ess
