Couldn’t the original bushing be drilled out? Or maybe carefully melted out so that the original mating surfaces could be left untouched?
.
It's a steel sleeve with rubber and another inner sleeve unit that is pressed into the arm. Hole saw the rubber out, die grind a line in the outer sleeve, collapse it and it falls out. Debur the ID(not hone), freeze new bushing, heat arm to 212F, press in new sleeve to correct depth(use sleeve retainer Loctite). BJ end would be more difficult, score arm pressing out, and more likely to fail than the bushings unfortunately. Have these components ever had a failure NOT related to an accident?
If somebody makes new arms, use different BJ boot material. lol
What's the story on those? Why a different material than 90% of the cars on the road that don't have boot failure. There are some other Fords that use that material too.
