I prefer the stiffer polyurethane or thermoplastic or whatever the aftermarket ones are made of cuz they increase the effectiveness of the sway bar. Mine had the blue Moog (or AC Delco?) ones already installed when I bought it and I later installed the matching frame bushings. Cheap and easy upgrades. Oh- no noises

Well, my fourteen year old daughter and I finished them tonight. Even with the tires off and suspension hanging, we had to put a pry bar on them to slip the new ones underneath, not bad once the wheels were off. Torqued down, buttoned her up, put all the tools away and took her for a quick drive. Steering felt easier driving around the neighborhood.
Since the others are not squeaky, maybe next time I'll get the others; maybe!
