2 Quick Questions Re:- Poly Bushes
I have Energy Suspension polyurethane bushings throughout on my 1989 GTA which were installed by the previous owner around 20K miles ago.

Silicone based synthetic water-proof grease, the white sticky stuff!"

I've had mine for over 9 years without any problems or grease. I do check them for any wear every now and then. Othewise I leave them alone and let them be. If you hear any squeaking then by all means go with the advice you got and grease up
