yup exactly as merlin said, gota build yourself a fast kingpin press, i have one thats just a rectangle with 2x3 tubing up the sides and 3 inch channel welded across the top and bottom, front and back kinda like a h frame shop press. just put a bottle jack in there and have at it, often jack pressure then shock the eye with a hammer helps. also if ya try the hammer method again, make sure the axle is blocked up as close to the end as possible to get the least shock absorbed by the axle, and make sure ya dont bugger up those fine thread that the kingpin cap screw into on most of the kw axles, been there done that! also ya shouldnt need a reamer with most of the newer kits, the kenworth kits are usualy some type of dimpled plastic bushings that are no ream type, just did a set last week, and the kaiser kits are spiraled steel that also dont need reaming. dont be affraid to throw a little heat on the eye, obviously not red hot, but warm often helps, like just enought to start to burn the paint and stop, this also helps to draw the penetrating oil into it too. dont wanna get it too hot or the temper of the eye could be affected, altho thats unlikely a worry unless ya get way too crazy with the torch which some guys do. now worst case scenario is that ya have to cut the pin above and below the eye, easy to do once ya cut the thrust bearing outa the way, then ya gota burn out the remaining pin in the eye of the axle, not fun, alot of molten metal rolling around, but did have to do that once! one more thing, not sure about all kw axles, but one time i beat my brains out on a IH kingpin only to realize it had two keeper wedges and i had only removed one!
