I've read what I could find regarding front suspension, in particular upper (thrust) arms/bushings...However, I have further interest!
I'm sure there owners who tries polyurethane (solid) bushings.
I'd like to hear form said owners on methods of installation and results after install. I don't need detailed point by point process, I would like to know nuances of such installation!

P.S it seems as if bushing (solid one) fits inside the metal sleeve. Is it true or it fits inside the arm itself after old bushing is removed?
