The Poly generally squeaks for those who use the improper lube, or no lube during assembly, and/or don't follow the recommended procedures for installing poly joints, which differ in installation than their rubber counterparts, I haven't had a poly bushing ever fail or squeak in my cars or customers cars,....if you buy cheap poly kits and assume they install just like rubber components, then that's when they fail, and get a bad rap...generally because of inferior products, and installation error,...a lot of the poly kits come with no instructions, so it's best to either ask the mfg for installation tech, or ask on the Moparts board, rather than assume the install, or miss steps, or do something that's detrimental to the bushings/components longevity...
