Just got done cutting the Energy Suspension black hard rubber bushings to fit the rear trunnion.
Not a job for the faint of heart.
Had to drill out the center to .540 to get the sleeve in. Ever tried to drill rubber? Had to hammer it in a 13/16 wrench and go very slow, it did get enough for me to get the sleeve in. This stuff does not sand, so a very slow process of rasping it to size. Had to remove from .871 down to .750 then cut about a 1/8 inch off the inside length from both to get to 2 inches. I did my grinding with the sleeve inside and tired to give it a extra little bit to compress into the upright. Took 2 hours, but the second one only 1/2 hour. Will do the other side later.
I do like the way the impregnated graphite is all in it. This is rubber and has some give, so might work better.
The large rubber washer that is built into each end will help keep water out as good as the original system, if not better. Neither system will keep it from coming in behind the bolt head or nut, so will give it lots of silicone.
The odds on it being worth the effort, time will tell. I will keep the ones I take out for sure.

Hard rubber bushings, lots of work.
