Suspension bushing hardness.

What is the hardness of most urethane suspension bushings?
Looking at projects down the road and wondering about materials on hand and alternative methods.

 

Kind of a tough one, but I think you will find most of them will fall in the 10,000-20,000 N/mm range for a smaller control arm type bushing.

 

I've heard from many a folk that Urethane can actually squeak whereas Poly-Graphite busings are much quieter. Just my .02

 

I'm toying with the idea of pouring a set to see how that works.
Found a place that sells the resin so you can mix and pour instead of having to mold it.
I really need to find my polymer textbook since i recall anything mixed as being thermoset and not thermoform. But then again, those little beads have to come from somewhere.
Time to Google.
