#27353, "RE: what size is the castle nut on the tie rod end?" In response to Reply # 3
kinda old, but a good post anyway. The nut is 17MM and you must use a air rachet or impact wrench to get it on if it starts to slip. I can't remember what size thread it is now but my old one was totally trashed. I replaced it (over 3$ for a new one) and put it on with the impact wrench. No problems since!
