TF is looking at different engineering options including a fixed bushing apparently but their position is that these bushing are good bushings as long as they are maintained and the harder you wheel the quicker they'll fail so you just need to deal with it. Sigh.
What a lame ass position to take. I can't believe that they actually said something as stupid as that! Funny thing is, their joints are Chinese knock-offs of Currie Johnny Joint which are made in the USA and will not fail like the TeraFlex ones. I've been running Johnny Joints on my white JK with coil overs for over 4 years now and haven't had to have them rebuilt once.
It's frustrating but at least TF responds quickly and tries to make you happy.
I don't know about you but a quick response is far from being worth the time needed to rebuild their lame control arm joints again and again and again. I couldn't even get myself to run their control arms for a year.
If you want to use Metal Cloak Duroflex bushings on the TF lower control arm Monster joints the part number is #7352. You are out of luck for the uppers.
The new Duroflex bushings will NOT fix the problem with the retaining rings blowing out. It's really a waste of time and money.
