So what are people's opinions on the uni-ball suspension things or whatever they are called and does anybody know where to buy them?

Like a grader ball and triangular link setup with a panhard bard for the rear?

I really like that setup. There are several builds on Pirate and remember that jeep at PJF last fall had one.

I remember reading somewhre that some guy in Quebec makes a real nice ball setup just for this purpose.

Are you thinking about this for the rear of the XJ? I good choice IMO. :beer:

Thanks buddy, I didn't know what they were called and I couldn't find them in Pirate, I think I may try it for now I think they might be a bit floppy from what I heard but I will see, if I really don't like it I will build a 4-link.

Eric and ElFab are the guys selling them in Quebec. PJF regulars. Personally, I am not a big fan of a single point of failure. I would not wast my time IMHO

I saw Eric's rip off his truck on Runner River, destroying both air shocks in the process. 300PSI air shocks make for one hell of a boom :)

Take the time to do a proper 4 link and never look back ;)

That being said, if you do go ahead with it, Eric's product is the way to go.

Did it rip-off his truck? So it didn't fail but his mount let go? I know what you are saying Adrian but I am working with a Cherokee underneath.....when I did the 3-link on the front I was agonizing over AS and angles and as somebody on PBB pointed out it is a Cherokee not a buggy you only have so much room to do anything so just build the damn thing and adjust what you can later and in the end I never adjusted anything as it seemed to work fine for me. Now a triangulated 4 link will take considerably more time and effort and spring is almost here and I can build this easily so I think I am going to try it. My other option was to leave leafs for this year but I was going to stretch it and......and......bah. If I hate this I will build a 4 link next year.

Yea it looks cool, but again - it is anti-engineering. As Adrian stated earlier - single point of failure.

Is Uniball the same idea as the Defender/D1/RRC rear suspension where you have an A-Frame and two trailing arms? I don't think I've ever seen anyone break one but I suspect the ones they use are pretty robust, especially given how much they weigh. If you're converting though just going 4-link or watts-link and radius arms seems to be a more sensible option. :)

I think you guy are over reacting on the one point of failure thing. Like John said, a three link is the same. There are a lot of guys down south that run this setup including comp. buggies with no problems. Any suspension will fail if not built right. If done right and can be packaged on your rig then this can be a very capable suspension at a fraction of the cost and build time of a 4 link.

I was seriously considering running this so I did a lot of research, but on the YJ I just dont have the room or the wheelbase to pull it off.

After a lot of research I decided my next one will have a triangulated 4-link copied from the one they put on the TLC Icon (the one with coilovers). Now that looks nice and clean.

Like Scott said, there are alot of big buggies and comp rigs running this set-up. I think it's going to be interesting to see how it works on the XJ.

If it is a trail-only rig then go nuts. Single point of failure on a toy or comp vehicle is fine, on a road vehicle it may not be road legal if experts do not agree it is a safe design (which seems to be the transport Canada criteria).

I am really looking forward to building the racer so I can play around with design :)

So with 1 A arm and 1 Panhard rod, I presume the A arm is pointed at the frame, correct? Would you not get a lot of movement of the entire rear axle assembly as the axle side panhard bar mount point drooped? I mean, the axle side mount will travel on an arc based on the length of the panhard bar, so wouldn't the whole assembly shift in that same arc?
