LBJ Uniball?
Anyone know what the word is on these? I remember seeing them first pop up a couple years ago with a bit of excitement following them, and then suddenly no word on them. They actually completely slipped my mind until this morning and I'm curious if anyone has sent in a pair in the time they've been out. Seems like a very appealing fix for LBJs - kind of a high cost initially but ball joints will only run you $30-40 a piece afterwards

I don't know anyone running them and I'm not at all convinced it's worth the cost. The one thing it doesn't address is the LBJ bolts themselves. I've sheared 5 of those in total. I've never once actually had the LBJ ball pull out of the cup. A few years ago I just sourced after market 10.9 bolts for the LBJ and haven't had a failure since.
I really wish there was a way to figure out how many LBJ failures where actually a failure of the ball and cup and how many where bolt failures. I'm willing to bet a very large percentage where actually bolt failures.

Uniballs aren’t supposed to be conventionally greased, just teflon based dry lubricant to keep them lubed. The cover is more to keep stuff out since it’s exposed without a rubber boot like a regular ball joint.

Did you torque them correctly with a dab of loctite though? If you did, thats scary if the OEM bolts failed which is sad. I though they only sheared off when they were over/under torqued.

Anonymous fab shows ARP fasteners as replacements. I was going to look into that and spec some out. 180kpsi strength vs typical 150psi in 10.9 and grade 8 applications.

Been a while since I've looked at knuckle LBJ mating surfaces.
Is there room in knuckle to accept a domed cover on backside of LBJ uniball same as it is on OE domed for clearance?
Would be pressed in on top of snap ring holding uniball in place.
Was just thinking on it. Pack area with lube cover it up.

For us I agree, for the masses NTSB determined a shear point would affect impact energy in a good way
they're the weakest link looking at the whole.

I picked some up from him with the uniball LBJ’s. Photo is in the link I posted.

Typical disclaimer, and also true. It’s still possible to shear one of the 4 bolts, and for the snap ring to fail. It’s just a much lower odds, if you ask me.

The 3d printed cover included fits in between the LBJ and spindle, just barely. It slides into the LBJ without affecting the movement of the uniball. I’m not sure offhand if it is pressing against the snap ring enough to keep it seated, but in theory shouldn't need to.

Properly torqued OEM bolts with loctite. To be clear they did not back out. They sheared. I also use my rig a little heavier then most guys do. Big tires, big rocks = snapped OEM bolts.

A uniball is no doubt stronger and the chances of a properly seated snap ring failing are pretty low. If he's shipping 10.9 bolts with the kit he's also aware the OEM bolts are the weak point.
For me the extra cost for going uniball isn't worth it. If I was a go-fast desert guy, like you, I'd make the swap without a second thought. The uniball is stronger and will also have a greater range of motion for sudden loading and unloading. Every tool in the kit should be tailored to the job. For my rigs job they make no sense. For yours they make a lot more.

Yep, even the oem bolts can shear, and Josh was aware of this being a concern when trying to make these as bulllet proof of a product as possible. He includes the 10.9 and the ARP are an optional upgrade. I believe the ARP bolts are grade 12.9.

You summed it up perfectly. It’s not for everybody’s wheeling style or terrain. I run some rock crawling trails but also enjoy some faster desert runs, and also live where it’s relatively arid. I would never run these if I was into mudding or lived somewhere that had a lot of rust issues. Uniballs can still rust out and I wouldn’t want salt from the winter roads just sitting inside the uniball. The 3d printed cap that’s included stops debris from getting in from the top, but the bottom is still exposed.

It would be interesting to see if a seal like this would work for the lower side of the uniball.
