Unfortunately, I think my RA bushings have about had it on my 94 EB 4x4. I was thinking of replacing them myself with some new poly bushings but am unsure of the amount of time, tools and technical experience required to do so. I read the Haynes manual, but the instructions seem to be a little vauge. I'm no machanic but I can do small things like plugs, wires, t-stat etc. My question is for those of you who have replaced the bushings yourselves. Was it worth the effort or would I be better off taking it to a professional? I'm not sure what a mechanic would charge to replace them, but I'm guessing it would be in the $200 dollar range. Any advice would be appreciated. Thanks
