Already have them installed, that is one reason I went with the Mugen LCA's, the harder rubber inserts. The ES poly insert for the LCA's front bushing doesnt last very long.
I was able to loosen the tierod ends themselves, the jam nuts were really bad, so I cut them off with a cutoff wheel, took a whole 30 seconds per nut. I need to find my die set and chase the tierod threads to clean up the rust.
One thing that I have noticed is that I did not need to use any camber bolts only OEM bolt's. With the MugenSS and the extended lower ball joints I couldnt get ANY negative camber, it sat with the top of the tires further out! I had to use a OEM camber bolt in the top hole and a SPC camber bolt in the bottom just to get 1.5 degrees of camber! This tells me the Progress has a fair amount of built in camber.
