I just finished installing the drag link rebuild kit for my 1950 chev 3100. In order to get the cotter pin through the end caps I had to use a long extention on the ratchet to get the end cap in. Now the drag link ball seem way to tight as I can not move it in any direction by hand. I have not used any grease yet which may be my problem? Should it be these tight on both the axle end and pitman arm end?
