Upper Control Arm Flex Joint - Goodbye old rubber bushings!

[@codybertram6122]

I’ve got a little over 10k on mine and they’ve already seen death wobble multiple times over 60 mph and rammed snow banks, banged ditches. I’ll let you know if they are worth it.

@codybertram6122 Keep us posted!

[@JoshuaWhitesinger]

How are they holding up?

[@codybertram6122]

@@JoshuaWhitesinger I haven’t even took the upper arms off to check them cause they’re still tight. At 20k on them now.

I bought mine a few months ago, with the installation tool… I’m installing tomorrow finally… thank you for the updated video! ❤

[@IronRockOffRoad]

@LaunceBugbee good to hear! Let us know how the install goes!

[@LaunceBugbee]

@@IronRockOffRoad I’m doing it as we speak… I’m having a bear of a time pressing the sleeve in…I’m using basic hand tools…

[@IronRockOffRoad]

@LaunceBugbee It can be tricky getting it lined up and getting it started. You can put a little grease on the outside of the press-in sleeve to help. We only use hand tools when pressing in the sleeve. A good 1/2" ratchet gives decent leverage and control.

Do they make these for WJ ??

[@IronRockOffRoad]

@txknightrider82 We do! If you are using the original 10mm bolts for your upper control arms you just need to select the 10mm option on the website. www.ironrockoffroad.com/product/upper-control-arm-flex-joint-8-bolt-10mm-cartridge.html Some of our customers choose to drill out the mounting holes on their upper control arms to a bigger size and purchase the larger 12mm or 1/2" bolt size.

Oh, wow. Now that I've seen how beefy that installation tool is, the cost (and importance of having one) is to me. Makes sense now. Thank you for this tutorial, well done and well explained/presented.

It would be cool to see same vehicle with flex vs rubber or poly bushings rti ramp comparison.

[@IronRockOffRoad]

@PTF491 That is a great video idea! I'll add it to the list.

What is the size of the Allen tool

[@IronRockOffRoad]

@raymondwinans978 The Allen wrench is an uncommon size, but it is included in each flex joint kit. The size is 3/32"

[@raymondwinans978]

Thanks going to see if I can find it for my inch pound torque wrench

[@raymondwinans978]

Found it at NAPA . $3 dollars for socket

Carlyle part # SH3803

[@IronRockOffRoad]

@@raymondwinans978 not bad at all!

[@benjaminvolesky1653]

Great for off roading and rock crawling. Not sure if it’s good for highway as these will allow more death wobble to occur.

[@IronRockOffRoad]

@benjaminvolesky1653 I disagree. Many times, death wobble occurs when suspension and steering components are worn out and loose. The press-in flex joint is the opposite of that.

[@raymondwinans978]

Death wobble is usually due to worn Track Bushing or movement. JLs are known to have the wrong size bolt and it eggs the hole . (Frame side ) . Ask me how I know 🤣🤣😕😕

[@IronRockOffRoad]

@@raymondwinans978 You're right.....among a myriad of different things, loose or worn track bars are certainly up there on the list of Death Wobble causes.

[@raymondwinans978]

I have just spent my future wifes honeymoon money buying a piece at a time . Should have bought the whole kit at once . But 🤷‍♂️. I had a damn this worn . I order a part Then i would go into it some more and find , damn this worn. Order a part . Then damn it that part was bad caused this part to go bad . F@#$_&#& too. Krder another part . I have as musch in shipping as i do parts now 🤣🤣🤣🤣

@raymondwinans978 Haha! We've been there! It's just part of the fun of working on old vehicles!
