I've had this happen with other drag links as well but I have the same draglink that you have and the boot has been torn for the last year.
only issue I worry about is making sure when I wash it, lots of rain or been on the trail I grease is as soon as I can until I decide how to replace it with something better.
Even though I have it centered and flat when on level ground, the draglink will flip to one side or the other on articulation pinching that boot.
IMO there is too much boot, I'm looking for a lower profile boot to replace it with...maybe energy suspensions
Which drag links you had problems with (besides Yeti)? It will help me cut down the list to look at. I am debating if I should buy a mopar (flopping) drag link and pray. The manufacturer from Steersmart told me that maybe the cause of my 'bad luck' is that my pitman arm has the hole bigger letting the ball joint sit deeper squeezing the boot.
So far after the holiday days are over, I am thinking:
1) replace the boot (have one last spare)
2) replace the drag link end (spare $140)
3) get other brand drag link.
If I got option 3, I am looking at stock, currie, and synergy. But I hear pros and cons from both currie and synergy too.
