Currie arms popping, is this normal for Johnny Joints?

I installed a complete set of Currie arms about 3-4K miles ago and they are now popping when flexed. When I take off from a stop I get a 4 or 5 “Klink” sounds. It’s been happening for the past month, getting progressively more noticeable. I had my son jack up one side of the axle and looked to see what was going on. The joints in the lower front arms are not moving freely, rather building up tension and then letting go in a pop or Klink sound. I greased them on install and re-greased them today, but it didn’t help. Is this normal?

Good idea, but no I just greased them with the Jeep level. I did drive it after and did a bunch of right to left turns to move things around though.

Back to the garage to jack, flex and re-grease. Hopefully it will work, I really don't want to pull the arms out to service them.

1. Load grease gun with grease.
2. Put grease gun fitting on grease zerk of arm.
3. Rotate arm joint with spherical center ball fixed in place.
4. Squirt grease into joint until it pushes out someplace else.
5. Repeat 3-4 as necessary.

That's odd. I've never heard a peep from any of my joints. Due to the JJ's design, there definitely should be no noises.

And unlimited, that's easier said that done. As I'm sure you know, the joints are tighter than a virgin. Very, very difficult to move the arm around the joint.

I tried it with a vice, but the center ball just spun inside the vice, no matter how tight I tried to hold it. I doubt other joints are that tight, especially the RC he's got.

to get the Currie's, I mounted them and went wheeling with a grease gun + rag, and just squirted them full at full droop and full compression in a poser pic position. I hit them every few weeks now...they're quiet as can be.

I can assure you the RC and Rustys joints are not. You can grab the ball and rotate it with little force.

Okay update on my Currie joints.

First mine are tight, almost impossible to rotate on the jeep. I removed one front tire, lowered it all the way and greased in intervals all the way up including stacking two 4x4 on the floor jack. Then cycled it up and down a good 10 times to work things in and unfortunately no luck. These things are binding and popping like party favors.

Only grease them through the greaseable bolts if possible. You will likely need to take them apart and clean the bolts out so grease will pump through them and while they are apart, give the ball and race a good coating of grease before you reassemble them.

Does this require special tools, I see Currie sells one for $79 but I'm hoping this can be done without that. Also does anybody know if Currie warranties their stuff. These don't even have 5k miles on them.

Well if they wont take grease. Take them apart and clean, Lube and reassemble. Dont try and pump grease if it wont go easy, Could possibly ruin the joint, For other parts as well. Good luck

How hard are these things to take apart? Has anybody on the board done this? Any tips would be appreciated.

I frequently use a shop press and a couple of sockets to disassemble the ones I work on. There is also a way to do it with some all thread rod, a couple of nuts, and some sockets. And, you will need a good pair of snap ring pliers.

If they pop when under load, check the jam nuts. I had one doing this right after the install. It wasn't the JJ, I had a loose jam nut.
