Greg,
     Delrin is not suitable for suspension bushes. The reason that
polyeurethane is used is that, in most cases, more than rotation is
involved. The bushes usually move in multiple arcs (in 3d) and delrin is
much too stiff to accomodate this, meaning that the suspension arm
itself has to accomodate the twist. Correctly installed polyeurethane
(with correct lubricant) doesnt usually squeak.
