When they're loose, you feel the *** end of the car loose too. It will sway just a bit from side to side. The directions aren't exactly user friendly either. "Don't grease, don't overtighten." Why doesn't anybody make a rubber type spacer that goes around the whole rod end to help quiet the noise. Seals-It doesn't make one big enough.

Yes it would. When I twist them by hand, I don't hear the joints making noise. I hear and see the phb hitting the mount that it goes in. On the lca's, the joint hits itself when it twist. If there was a rubber cover over it like I had on my rod ends, then the metal joint would hit the rubber first.

Our original design did not use set screws, it used an internal lock washer that applied pressure to the inside of joint. It worked well for us and the testing we applied but some customers had issues. We changed the design to a locking set screw in May.
Whether its a UMI joint or a Spohn joint and it has a set screw there should be no need to tighten them that often. Maybe check them once a year. But turning it in 3-4 turns a week shouldn't be right. Is the set screw missing and allowing the ring to back off?

I've had mine on for 6 months and probably 4k miles now and I had to tighten the delsphere ends once after a month or so which I assume was just the delron material compressing slightly. I had noise coming from them again shortly after that, but it was the mounting bolts themselves that had loosened up.
Message to Spohn, UMI and other manufacturers - some of us are doing some of these installs for the first time. Instructions should emphasize the following:
1. Body mounting surfaces that mate with the poly ends should be perfectly clean before install. I had some undercoat overspray on one of my mounting points that caused squeaking. As soon as I cleaned this off the squeaking went away. THESE AREAS NEED TO BE PERFECTLY CLEAN BEFORE INSTALL!!
2. Grease the surfaces of the poly ends that will come in contact with the body surfaces. Don't assume the zerks will take care of this. Do it manually before install.
3. In the same way, grease the insert rods in the Delsphere ends before installation.
4. make absolutely sure that the mounting bolts are torqued to to 80 ft/lbs. This needs to be done with the suspension loaded but is very difficult to do on the ground. I accomplished this by lowering the rear tires on to ramps and then torquing. Then retorque again after about a month.
After those lessons were learned, I have been very happy with my LCA's but I don't think this information should be learned by each installer.

That doesn't sound good. Have you taken the Delsphere ends apart and inspected the delron bushings? It sounds like maybe your bushings need to be replaced if you are able to compress them that much. I would disassemble them and see how they look. Maybe you just got a bad set of bushings.
