I do not know what the tie-rod size is on X units, but on the Gen 1 I researched and found an automotive tie rod end that I modified and installed. For our lightweight units it is seriously 'heavy duty' and with a grease fitting, I think they were about $15 each. Ought to last forever. I could not find a greaseable heavy duty tie rod end for the Gen 1. The one negative is that if I have an event, the end is not the weak link any longer. It goes to tie rod or the rack.
Install the heavy duty set and carry the good one as a spare with the tools to change it.
