hello,,that bolt welds itself in there basically,,took me an entire day to beat,cuss,torch and anything else i could think of to get mine out..ton of wd40 and a lotta sweat...one side note though,,if there is still tension on those springs dont have any body parts above or below the spring when that bolt does come out,,wasn't thinking and when mine came loose it hit the bottom of the bed so hard i thought it tore the truck up..lol
