Have you actually unbolted the heim end and checked it by feeling the sphere with your hand? If not I would do that, even if you can not see movement while rocking your jeep/with a prybar/etc.
If it just started doing it after 3 months and you haven't changed anything then it has to be a worn part(s).
Take one end off of the stabilizer and push it in/pull out with by hand to make sure it's still stiff, the faster you go back and forth the harder it should be to move the shaft. We almost always use the RC stabilizers because they work great and we have had 0 problems out of them, but that doesn't mean you didn't get the rotten egg twice.

Any 3/4" (i believe they are 3/4") right hand thread heim will screw in. Take it off and go see your local offroad, race car, or low rider shop and they should be able to get you the correct part.
