OK.....took the upper unit on the out drive apart. The smaller bearing on the ball gear shaft is scattered. My hard steering issue was from all the pieces of metal in the upper getting caught in the worm gear and steering gear. I think the ball gears failed from the shaft moving around so much. So, im looking for a new upper. all the gears and bearings are shot. I think i am alot further ahead to replace than rebuild. What years and ratios can i swap in?
