Gosh this thread derailed pretty fast
From the OP, any updates? It almost sounds like an assembly issue. I have never had issues with Johnny Joints and had been lucky even running Rubicon Express arms. I think most parts pushed hard one way or another will wear out, but as mentioned if you are paying a good chunk of cash you expect the stuff to work.
I am debating what suspension I will be going with on the ton swap, but on the same page want the stuff to do well on the road and trail. I have looked at EVO, MC, RE, RK and others out there, and may end up doing a mix and match of what will work for my rig.
To the OP, please report back on what happened with your stuff and MC and what will be done about it.
Thanks!
