Don't know if this would apply to cab bushings, but there is the squeak factor. I think you gotta grease up Poly or it'll squeak. I don't know how long that grease stays there before it goes away. Then the squeaks begin? I don't know the answer.

But my truck came with rubber, as I'm sure most did. They seem to be in pretty good shape even now. After all that time. Hard to justify changing that for a rougher ride.
