i used the QA1 non-PTFE version of the ones Kuah uses on TC rods that i made last year, also used them for sway bar endlinks

the rod ends lasted a full year with no problems including being driven through winter in Canada. i never greased them or anything and did not notice any noises.
then i wrote off the car and snapped the hardened steel portion of the arm... the aluminum rod was fine but you can attribute that to details of the impact, angle, load etc.
for the stuff i make now i have a whole load of the top o' the line QA1 3-piece seal sealing ends coming in this week. cant wait.
up here in Canada we need rod ends that will kepe dirt and salt out of the rod end, that is why i decided to overkill it.
