"bigblue" 94 ZJ on 3/4 tons and 37s

Pretty sure he means the UCA brackets on the LCA are angled differently.

[Jim311]

Yes, the bracket has a slight downward bend to avoid that problem. The pic doesn't really show it.

[bigbluezj94]

im probably going to have to cut the UCA brackets off of the LCA and turn them up some. this will also require a bigger angle at the top where the "u" shaped bracket meets the bushing. i think that will solve it.

[Technohead]

really?? they look straight to me?? i know the pumpkin side has an angle at the top, mine do too..



sitting flat i have a good 1/2 to 3/4" between the yoke and the arm. the actual housing is nowhere near it.

That must be a picture of an older design or something. Mine has a small bend on the drivers side. I attached a picture. The angle is just there to clear HP pumpkins. Not sure if this is your issue or not. . .

thats not a bend. they cut the end of the tube at an angle. i did that to mine as well...

[bigbluezj94]

so ive heard of people wearin out the lower control arm bushings but what about the uppers? mine appear to be shot already!

[ArloGuthroJeep]

Other way around, UCA's get worn out pretty easily due to the binding they get into when flexing. I replace my UCA bushings every 12-18 months (as opposed to every 9 months with short arms).

well its only been one month and they are ate up. im going to put some JJs up there. keep the binding down to a minimum

[ArloGuthroJeep]

Sure all the CA's are the same length? If they were in a constant bind, just while sitting level, that'd do it to.

[AgitatedPancake]

His front axle drops waaaaay out Ryan, unseats his front coils pretty far. I say thats killin em.

Bad idea - radius arms only flex through binding. If there is no bushing there to absorb/ allow the binding, you will not have any flex.

well ive since learned that JJs are a bad idea. Has anyone had any experience with Poly up there instead of the stock style bushings? they would still allow/absorb the binding and should last longer, right?

[snarfer86]

I don't have Claytons, or a radius suspension at all for that matter.. but what about only running one upper?

Also.. if your unseating your springs you have more flex than you can use.. have you thought about getting a set of limit straps? letting the axle hang from the shocks will destroy them in short order..

[Ramsport59]

bigblue, I had the same issue with my arms eatting rubber bushings when I had stock axles in place. I built the new uppers with Poly. But havent made it out wheelin yet.

[AgitatedPancake]

Ram I was the one that suggested the poly on another forum, but I actually haven't seen the actual product for this application. Do you have a link to the ones you used? I'm half tempted by them also because as Blue assumed, they should last much longer!

[Ramsport59]

I used some from Ballistic fab....they wont fix stock locations.

Bullshit.

I run JJs in my Uppers and have no binding issues at all.

CLAYTON himself suggest going to JJ uppers and that what he puts on allhis custom built axles, and his bracket kits come that way.

[FortCollinsZJ]

Both ends of your upper radius arms? good to know, I just put in some currie press in JJ's on the upper mounts on my hp30 yesterday, then saw it was a bad idea, then see that it is fine!

[faststang1]

As far as I can all link systems will bind.A buddy of has a XJ with BDS 4 link kit on it and he say it still has a bind just like my Clayton does.maybe not as much but its there.
To me its not a big deal to change upper bushing,it just keeps everything fresh.JJ seem like it would be a good idea to get rid of some stress

hell yea. im prob going to grab some JJs. after this weekend, my bushings are even worse.

FCZJ, currie makes press in JJs that go into the stock mounts? im only seeing ones that i would have to chop off the old mounts and get some new dom to put them in.

[Technohead]

Check LSRGreg's build thread. Pretty sure he used some sort of JJ for his uppers.

sweet, i just found the JJs that press into the stock location. these should work just fine with my setup to where i dont have to cut off and re-weld any new mounts. if there press into a stock location, they should press into mine because a stock bushing is in it now... lol

thanks

[blackzj52]

whats up troy!

yeah currie makes JJs. I was considering buying some for my hp30 build up. still need to think that over some more.

oh and buy my windows already

doing my taxes now. haha i got other fish to fry

[slim616]

Hey let me know how those JJ work out for you. my RE uppers are shot also and i'm deciding if i should just replace them or go with something different.

Rigs looking pretty good. You may want to go with full hydro to push through that welded front. ive been told that alot of comp rigs go with the spool up front and a selectable in the rear. the theory is that the full hydro will push through the spool and the selectable will let the cutting brakes work properly.

I have a lock front in the front of mine and it works flawlessly but granted its the 60 version.
