umm jack up the front take the 2 bolts out of the bottom and take the nut off of the top and tke them out...reverse to put them in....not a big deal when your taking the top nut off....the sock may spin......soo..what i suggest is taking and buying som "PB Blaster" and soaking the top nut for a day...like keep sprayin it and it will make it a lot easir......but the shick rod may still spin if it does take a pair of vise grips and hold the top where the squard off part is.....be sure to clamp down on it hard..and use a 13 wrench to spin it off the rest of the way...
hope this helps
Kenny
