There have been many discussions, about rubber vs poly bushings. If you do a search, you should have all your questions answered.

I run all poly bushings on my 73 Dart. They are more expensive, last longer, but it rides a lot harder than any of my other cars.

hi, poly everywhere except lower control bushing. ron

They tend to squeak a lot. I have the poly-graphites from Energy Suspension which are supposed to be quieter, but you can still hear them. The ride is MUCH better, though....
