Just finished doing all the tie rod ends on our 2000 Quigley. What year is yours?
Something is different on your Passenger side AND the Driver side Tie rod ends where they attach to the steering knuckles. Here are pics I just took:
Note how the passenger side and driver side tie rod sits above the steering knuckle vs yours which are below. There is a taper in the knuckle to match the taper on the tie rod shaft. Not sure why yours would be different but the knuckles look different on yours, too. And, looking at Herb's thread, his are below as well. Maybe this is why you are getting the unusual rotation in the tie rod ends???
If you have to replace the ends: they were pretty easy to replace. RockAuto.com for the three small ones, about $120 for those, Quigley for the big long one $225. Tool loan from O'Reileys - free. I soaked everything with penetrating oil for a day or so before tackling it. Torque setting for all four tie rod ends is 67 ft-lbs. 41 -lbs for the coupling clamps. You will have to set toe and steering wheel after you finish.
Important note on Quigley Tie rod - It comes with a thin washer. This washer goes between the castle nut and the knuckle.
If you want, I have a Quigley tie rod end here in San Francisco you could buy pretty cheap if it fits your rig/year. I am pretty sure it is okay and I did not need to repalce it. The tech who replaced for the prior owner put the thin washer between the tierod body and the knuckle. This never allowed the tapers to mate and thus it appeared to be worn out. It wiggled because the tapers were not seated.
