The only issue I have had with JJs is their loss of shock absorption vs clevites. This would especially be an issue on the front control arms on a lifted TJ. They would see a lot of axial impact that would benefit from the absorption ability of a softer joint. Not sure if it would help the ride, but certainly would be easier on chassis components.

I think the ideal joint would be one that has the durability and flexibility of a JJ, yet has the shock absorption of the OEM clevites. This joint seems to be the perfect joint (if the long-term durability is still good.)

Imped... you said there was a definite improvement in ride, but you did yours one whole end at a time right? If you can't do it all at once, where do you suggest beginning to see some improvement right away?

Thanks-
I have the same q- replacing re lowers - fixed and RC x-flex uppers

And you're basing this issue off your experience with double-ended Johnny Joint equipped control arms?

I always thought of it as a possibility with double JJs, but even more so considering the info in this thread. Intuitively though, the more cushioning, the better, to a point.

Imped, I'm going to be watching this thread for durability reports (from anyone).
My Jeep is 99% daily driver until the worn out parts are replaced (entire suspension). It'll probably be a year or so, hopefully you'll thrash these joints worse than a ginger stepchild, and they'll pass with flying colors.
I'm in Columbus, I'll have to join you guys at Attica sometime. Haven't been there since the ownership changed.

This is my thread and it's on the MC bushings and Currie JJ's, not link design. Take your discussion elsewhere if you're gonna turn my thread into one of your ***** fits. The J arm thread is on page 1.

As for the JJ guts, I'm linking a CJ-7 and it's getting JJ's. The owner has JJ housings and I've got the innards. That will save him money and will put good parts to good use.

I just put JJs on my front and rear lower mounts. I am going to put the MCs on the front upper frame mounts on my Full Tracton LA equipped LJ. If I want to swap the lower innards of the JJs with the MCs do I just remove the circlip and slide them out and push the MCs in? Can it be done under the Jeep by just unbolting the JJ? I am looking for the ultimate in comfort and anti vibe for my Jeep.

within the passed year ive become extremely obsessed with shocks and suspensions. not only in jeeps but in BMW's, motorcycles and old muscle cars. if they hold up, id like to see em in some linked muscle cars.
Late response....MC has been running these in a DD JK (Hemi maybe?) with 40's that hits some hard trails often. No wear to speak of so far......

I'm sure it CAN be done, however by the time you are done you'll want to murder someone.

You'll need to throw the JJ in a bench vise and either buy the tool, or rig your own up in order to compress the bushing behind the clip enough to get the clip out. It will be easiest doing it that way.

Looking for: 03-06 interior plastic trim. PM me.

I can disassemble a JJ in about 30 seconds without any tool to speak of. Like I said earlier, the tool is only need to generate the preload required to get the C clip inserted into the barrel groove when assembling. Not needed for disassembly or setting the C clip when assembling with the MC bushing.

You do know that JJs and Mc Duroflex joints are not recommended to be combined on the same arm according to Mc. Its been mentioned often but it sounds like it may need to be brought up again being it sounds like some may of done it any way.

Reasoning they shouldn't be mixed--the friction force between the JJ center ball and bushing halves > the force it takes to misalign the MC bushing. So, the JJ will dictate misalignment orientation between the two. If the situation were reversed, it'd be fine to mix and match.
