I just replaced mine with the Energy Suspension polyurethane bushings (Mudflaps.com had the best price) and was surprised at what it took to press the old bushings out of the "dog-bones"! I have an Acetylene Torch and hydraulic press so, I knew
they were coming out
But geez, was still kinda impressed with the force it took...
I first went to Rock Auto and there were just So Many listed (how could these have All be applicable for my truck?) that I though "well, I have the right length ones there now, maybe I should just fix them" and decided to do the bushing replacements. It was 1/2 the cost of the Moog problem-solvers and I also put the fittings in the link ends and swaybar mounts.
