I'm currently in the process of rebuilding my D60 and regarding the king pin, Do any of you actually replace the pin itself or everything above it on up? I have the D60 manual and it says that the new king pin needs to be torqued down to 500-600 ft lbs. Holy Smokes!!!! Plus it looks like it requires the use of one hell of a large allen wrench or an allen socket thats big enough to fit in there. Any ideas, tips? thanks..
