If you decide to use any kind of Heim joint, be sure to lubricate it often. They do not have the ability to retain grease like a ball joint or tie rod with the grease boots.
If you run them without boots (as I did on my Challenger for close to 70k miles) you need to use a dry lubricant, like a graphite spray or similar. Grease, oils, etc will just catch dirt, might as well use valve lapping compound. Gotta run boots with a wet lubricant.
