When the stockers start making noise, Ford offers a better rubber part when they replace them. A great way to deal with the 24mm ones is to buy the Energy suspension bushing kit for about $25 and install them yourself. A rubber hammer and some lube is all you need for install and a propane torch takes care of the extrication of the factory elastomer bushings, if they are still bonded to the steel at all.
