Why the hiem joints on something that does not move?
Not the first time we have seen this https://wranglertjforum.com/threads/weird-track-bar-contraption.34718/
That is crazy there is enough movement there to be noticeable from the drivers seat.
I've helped on enough steering tests with the engine running to notice that the frame side TB mount move moves side to side quite a bit. I've also seen a few cracked mounts other than mine.
This movement is a significant reason to add hydro assist. It takes stress off of the TB mount.
