Ita a big job but it will save you big money! Do all four,get a c-press,the biggest vice you can find,the ford locknut socket,an impact wrench and a 3/4 inch drive wrench and socket set,thats what I used on my 86" and all is well.If Ford hasnt changed things since then you should be allright.Firestone wanted 350 bucks for the job and I would rather spend the money on tools!!! The hardest problem I had was getting everything off just to get to the steering knuckle.The spindles were great fun.Wooden block, bfg hammer,air hammer, but I finally got them off.
