LCA Bushings and Other Bushings
That poly material squeezed out of the bottom is the poly material being squeezed so much that it’s forcing the poly material into play dough. It’s squishing out the back
when you installed your LCA by itself, does the LCA move up and down freely? With the LCA off the car, can you rotate the pin a little? Should rotate, but be tight
When I installed my poly LCA I shaved them down to fit the LCA hole. And I sanded and polished the hole with porting scrolls. Removing any burrs that could keep the LCA from freely going up and down.
I also polished the pins that you leave the old rubber metal sleeve on.
I installed these in 1997 by hand, no press. They went in hard, I used a block of wood to help.
We removed them in 2010 at Hotchkis to install their kit. They said (and I saw) they still looked good and we re-installed them.
* btw the pin in the middle below will not accept a poly bushing *
