Building UCAs - Joint Questions

I will be building a pair of adjustable UCAs soon. I'm going with a Johnny Joint on one and a rubber bushing on the other.

Here is my situation, right now I'm building these because I'm doing a belly up. However, I would like to reuse the joints when I build long arms in the future.

From what I can tell, the stock bushings are 2" wide. Since I'll be using the stock brackets for now, I need to use 2" joints.

Johnny Joints

Rubber bushings

Does this sound right? I would like to get 2.5" JJ, but I'm not sure if I could mod (bend) the brackets and make it work.

Also, does anyone know of good rubber bushings that come with a sleeve?

I'm looking for any input that you guys might have.

you are correct sir. 2.5 JJ's won't work without surgery

Look at the stock replacement bushings for the rubber.

Cost is the only real reason.

EDIT: I see you're running a Clayton kit, I thought they used a rubber bushing at one end? Or is that just the lowers?

That plus having that kind of joint at both ends makes for more shock and vibes being transmitted into the Jeep through the control arms. Having a rubber bushing at one end serves to isolate that out of the cab for rigs that aren't pure trail machines.

I guess it depends on how your arms are constructed...but I'm sure you could.

Does anyone know what size tube I need for the outer shell of the "RE small upper bushing"?

EDIT: I ended up going with these (free shipping): http://www.alljeep.com/oscommerce/pr...ucts_id=168722

This is more for my own reference, but here are some tube adapters that will work with the JJs I'm using. Size #4 to work with my 1.5" O.D. x .120" DOM.

Just thought I would update this with some pictures and comments on my experience.

I went with the Ballistic tube adapters, very nice and beefy.

One note about the RE bushings and sleeves. Our initial attempts at pressing them into the sleeves failed. We placed a 1" plate on top of the bushing and tried to press them in. What we found was that if you press anywhere on the bushing itself, it expands and will not allow the bonded sleeve to "crush" down into the end ring.

Let me step back, the bushings are bonded to a sleeve. The sleeve has a flange on one side and then tapers down after about 3/8" to a smaller diameter. The end ring (the portion actually welded to the arm) has an ID the same size as the smaller diameter of the bushing sleeve. When you press the bushing into the end ring, it sort of crushes down and gives a really tight fit.

We ended up using another end ring on the bushing flange and it went in like butter (figured a 20 ton press was enough )

Here are some pictures before I cleaned up and painted.

So can you give us an idea of the cost on all of this?
