Poly is best used where motion is linear (does not arch). With that in mind, here are my suggestions.
•Good: Upper Control Arm, Rear Leaf Spring, Roll Bar End Links
•Questionable: Roll Bar Intermediate - strongly suggest using only ones that have Zerk fittings if you use one here as you'll need to lube with regularity
•Poor Choice: Strut Rod, Lower Control Arm
As Lou said, use plenty of lube - unlike rubber, which is installed dry, poly is designed to use a lubricant to limit friction and noise. Better designed systems have provisions for grease/Zerk fittings.
All that said, many people have installed poly in every conceivable bushing location with no troubles, but by design, they are best suited to linear applications.
I could be wrong, but this is my experience & knowledge (worth $0.02).
