My Superb 2.0 SE business tdi estate just passed its MoT with the following advisory:

Offside front suspension wishbone rear bush debonding.

Before the MoT I replaced the tyre which had heavy wear on the inside edge.

Would I be better replacing the bush or the wishbone complete? People also talk about replacing the steel ones with alloy from an Audi. It this worthwhile for one side only? In which case what it the part number? The car is now pushing eleven years old with 86,000 on the clock. It is our workhorse.

I'd change the whole thing given the age and mileage; components are going to start showing their age so you'll be saving hassle by replacing the arm which includes 2 bushes and the bottom ball joint. You'll find they're just as likely referred to as Lower Control Arms or LCAs. You can get the aluminium ones (pattern parts from Autodoc) but you have to be careful which model as per this post - Passat and Arteon are ok, Golf parts are not as they're too short so make sure it isn't that.

I'd also consider changing both sides as it goes, for the same reason.
