Question regarding Currie upper control arm Johnny joint

[jxv1247]

It's about time to replace the upper control arm bushing on the drivers side of my Dana 30, and was looking at options. Is it worth going with the currie press in Johnny joint vs something like a Moog bushing ? Fronts a 3 link if that makes any difference.

This is the Johnny joint in question

That joint isn't big enough to handle the work of 2 joints so it won't work very well for a single upper. Truss it with a mini truss and put a lower joint and mount on top of the diff if you insist on a single upper.

the Dana 30 under the jeep currently has a Barnes truss I welded on a few years ago, wouldn’t be too hard to make something along the lines of that work.

Like that but not necessarily with the stiffener. Clayton used to sell one but I can't find it.
