The current bottom wishbone bushings don't need grease. They are sealed from the factory and (in a way) pre greased. The cap is often called a grease cap, but on a Montreal with the new wishbone bushings it's really a dust cap.

As Don says: it can't hurt to apply grease on the nut and the locking washer to slow down the corrosion. Those bushings will probably stay there for another 30-40 years ...

True. The Italian parts catalogue calls the usual suspension rubber bushings for 'silentbloc', while this particular wishbone bushing is called a 'boccola'. A boccola is a plain bearing with no moving parts.

Interestingly the crankshaft bearings are called 'cuscinetti', not 'boccola', but that's another discussion ...
