Installing the new JJ end for my Currie track bar and found some concerning things. @mrblaine Have you ever seen stress cracks in a JJ centering ball?
My track bar came loose in 2021 in Moab while with Josh and Matt. We tightened it back up on the trail and I retorqued once I got back to where I was staying. However, this side of the centering ball has certainly seen some movement to wear off this much material.
Looks like I’ll be ordering a JJ rebuild kit for the frame side.

Almost looks like the worn side may have cracked first and chipped off.

Perhaps…I should have removed and inspected my track bar rather than just checking torque spec on it. Maybe I would’ve caught it sooner. I don’t know. Aside from the time it came loose in Moab it has always been at spec torque when I checked.

Ok. Here’s my theory. There are a couple times I’ve let a shop do the work on my rig—both times they fucked something up. I thought maybe one of the dumbasses used an impact on my track bar bolts and severely overtorqued them, leading to stretched bolts that will never hold spec torque.
So, to test that theory, I installed new hardware frame and axle side and took for a test drive. Results, no DW no matter what bumps or series of bumps I hit, nor on the known areas that always provoke it. Surprisingly, I’m not even getting the slight shimmy I was getting. As of now, it seems to have been solved. I’ll be changing my sub name now.
In light of the condition of the centering ball, I’m still ordering and changing it.

I've not seen many with stress cracks but if you wear the center out of the enlarged washer area and then tighten it back down, it should do that because they are a case hardened piece.
