Got a replacement Warn stub shaft and the Yukon Super Joint went on perfect and rotates perfect. Pressed on the old inner and the joint is extremely tight to the point you can feel the metal grinding. Took it apart checked it good (caps and cross), deburred the trunions, no joy. Tried putting a good Spicer 760 in the inner and it was also very tight to turn. Could the ears of inner shaft be tweaked to the point the bores are out of alignment? No way the Super Joint cross is tweaked.
