[DeTomaso] [POCA Forum] A-ARM BUSHINGS (Pantera Technical)

Mine don't squeak either and I haven't greased them since installation. I'm
pretty sure they are polyurethane, because I remember them coming with goo.
Mike Drew hand-carried them to me so maybe he could confirm..

This begs the question are all the vendors polyurethane offerings the same?
I have poly bushing and can't remember when I last greased everything, but
never had any squeaks.
