Nick,
When I installed mine the first time, I had the same issue as you with the Zirks not working. It is all part of the poor design IMHO. When I pulled everything apart, due to the problems getting them aligned correctly, one side was really badly deteriorated/chewed up by the inboard mounts. So, I called TC and talked with them and ordered new bushings for both sides. According to TC:
- You should only use super lube grease.
- When you grease them, mark your cams with a sharpie in case the cams move.
- Loosen one cam, give about two pumps of grease. Re-torque
- loosen other cam, repeat
- repeat for other side
Since then, I have followed this and had no problems. I get my truck aligned once a year right now and grease these then get the alignment. Also, when I installed these, I followed Spressoman's advice (above) and used this grease to lube everything the first time:

It works great. Now I just hit it with the Superlube for periodic maintenance. On My rig the uniball seems to be the one that squeaks more often... Just hit it with the spray

Spresso also told me that when he ran this design of UCA he found himself having to lube things multiple times on a trip. I have not had that issue. But, he hits the trails way more often than I do. So, you may find the same. The Slee option if turns out to be more reliable (I.e. doesnt need the regular maintenance) and get alignment within spec every time, they will be a much better or really the only solution.
However (for those reading), Dont buy TC or JD UCA's for promises of getting caster back within spec. Ask around and you will find more have been unsuccessful than have succeeded in that endeavor. 99.9% of users do not need what these provide. Slee's may prove to be the solution most are looking for and I hope they do. Others are not for now.
When I got these, I did so to go as fast as possible in the desert. And they are great for that. There is nothing like driving 60-70+ mph in the desert. But, both kids are getting car sick now when I go too fast and find myself going much much slower. If I were buying a new suspension right now, I would stick to OEM uppers and a OME/Billstien shock combination. The added down travel isnt as huge of a deal as everyone thinks it is. I am not going any place with it that I couldnt go before. The gain is most noticeable at speed to me. The trade-offs for a remote res shock and TC UCA are not worth it for technical or slower speeds. It is a very harsh combination for DD duty. Especially with the crappy roads here in San Diego. The idea of low or zero maintenance is much more appealing to me. Of course others will have differing opinions on this. Hopefully some will post. It will provide food for thought to those thinking of going this route.
If after time the Slee solution proves as reliable as I am hoping they do. Next time I need to rebuild my TC arms, I will be replacing them with the Slee. If not, I will probably go back to OEM.
