ha.. OK, I got all the bushings pushed out. "Practiced putting one back in and the sharp edges sliced off the flange, and yes that was with grease.
Used some sandpaper and dulled the sharp edge, pushed the stock bushing in pretty easy.
Then went for the GroupN bushing... HOLY CARP! That's a tight fit. It seems to work like a squeegee and wipes the grease away as it goes in. Any suggestions on super slippery stuff for that? I was using white moly grease and got one in after two trys. I stopped while I was ahead and hadn't broken anything
Oh yeah... good thing I ordered the bushings.. one of the links had two outside bushings in it instead of one outside and one inside
