Unfortunately, it only takes wear in one side of the track-bar to create movement in the front end of the Jeep.
As for the Flex-joints being noisy, they may make a little more noise than rubber, but not much more. Most of the Flex-joints have somethng equivalent to a Nylon race installed. This should dampen the vibrations quite a bit more than you would experience from a Heim joint. I currently have 2-Heims and 1-Flex joint in my rear upper A-arm and it is not terrible. In-fact, once I get over my initial scrutinizing of the Jeep ride (after not having been in it for a while), I even forget about the slight difference in the ride after a few minutes.
I am going to take a look at the Ruff Country 1084 Track-bar. Generally they are designed for specific lifts only...
