I bought a urethane kit from online. It involved making a mold of the factory rubber bushing by just placing the bushing in the mold then removing it. Now that I had the mold I mixed the urethane ingredients to the desired durometer rating and poured it into the mold, then waited for it to cure. If you pour it slowly, then you will get a more solid unit without air bubbles curing inside the bushing, which would weaken the bushing I am very pleased with results. I looked up on Moogs website they now sell white colored polyurethane sway bar end links for the Aurora, so these bushings will make the front and rear sway bar entirely poly. In the picture. 2 of the 4 poly bushings I made are at the top and the factory rubber bushings are at the bottom for comparison.  |

I used a company called , "Smooth-on." I spoke with the customer service rep b.c I needed assistance selecting the "shore" strength of the urethane. I wanted the urethane to be firmer than the factory rubber, but not hard as a rock. These were made some time ago and I was cleaning stuff out of my closet and came across them. It was perfect timing b.c I needed to change my end links. So I forgot a lot of the details about the urethane etc.... There are other companies too like , "Polytek," and "UScomposites." I'm sure Amazon sells kits also. It wasn't cheap but I was really wanting urethane for every suspension piece in my car, so I bought it and gave it a whirl. If you squeeze the factory bushing on the side. It squeezes down somewhat. If I do the same to my urethane one. There is very little compression! And the great thing is it still has give to spread apart so you can fit it around the sway bar.
I really want to experiment doing it with a motor mount next. Making the mold will be easy. But, It will be difficult chizzeling the rubber off the metal base. I will buy an aftermarket one and inspect it to see if it's possible. That would be awesome if I can do this since I already have the NP tranny mount.
Thanks!
