I haven't had the time or the inkling to work on this truck until recently. I have tried several methods to get this hub apart with no success. I am now trying to pull the whole assembly, steering knuckle and all. The problem is, with the axle shaft still in(I can't remove it until the hub comes off) there is not enough play to remove the knuckle with the axle shaft installed. I am trying to remove the upperknig pin. It looks like a 7/8" Allen tool will do the job, but I can't find anything that big, unless its made of brass. I saw an older post about using a spark plug socket. I'm still trying to find a size that has that size end on it. If anyone else has any ideas, I am more than willing to hear them.
