Dude, pretty sure you've proven yourself. Smack a forum bumper sticker on it if you're that concerned.

Bind up where? We have one similar in the very first SOA I did 13 years ago and its still living I plan on pickin her up with the forklift when I am done to see how close everything gets.

BTW if you all want to see my truggy I will start another thread for it, just not sure where it needs to go

I'm no suspension expert (hardly even a novice for that matter) but with multiple hard links of varied length attached at different locations on the axle it seems to me that something would want to bend, stretch or break at some point in the travel. The axle path on a leaf sprung suspension seems like it would be up and in the direction of the shackle in a slight arc as the spring flattens and lengthens in front of the axle. The wishbone also has an arced path but with different attachment points I'm not sure they would be the same. I'd love to see it in action, when it's done or if you've got pictures of your other rig where we can see the suspension working at different points through the travel.

My other rig is a totally different animal being it has coils...the coils are really close together, and the wishbone is over 3 1/2 feet long; so you really cannot compare the two. The reason for this setup in this jeep is to keep the axle wrap under control and still allow the rear axle to travel. Not sure what you are saying with the multiple hard links statement, there is only one attaching point on the frame side and two on the axle (but those two are on the same plane and will move as one) The reason I only have one joint in the front is to allow for suspension movement without binding; if designed with two bars and two joints, it would bind.

Well, I wasn't sure of myself so I mocked it up in cardboard and I still think you may run into some issues. The multiple attachment points I was referring to are below.
  1. Leaf pack to top of axle
  2. Leaf to frame
  3. Wishbone to frame bracket
  4. Wishbone to bottom of axle
Now, my mock-up only allows movement in one plane so it best simulates a square hit like a curb or speed bump but that's good enough I think to illustrate my point. With a fixed attachment at point 1 (the spring should not slide or rotate on the axle) and pivots at the other 3, I see one of two things happening based on my model.
  1. The spring is going to try to twist around the axle as suspension moves upward and away from the axle as it moves down.
  2. The wishbone is going to want to lengthen or shrink and will twist the bracket or break itself somewhere.
The wishbone design works as well as it does on the coil sprung rig because the coils themselves allow some twist to happen, by their very nature the movement is different from a leaf sprung axle.

It's all good. I'm just getting into the whole Jeep thing but I usually have a pretty good eye for mechanical things and something about the wishbone link didn't seem right to me. I've got no problem being proven wrong and I'm going to keep on watching to see if I will be.

If I can get my bro in law to bring his out I will show you sooner, his has been done for 13 years and never had an issue.

I'm new to the Jeep world myself with this being my first Jeep and I've learned a ton and enjoy every minute! I think if you look back at post 116 and 117 where you see the ballistic joints used in the wishbone, I believe they will allow the necessary rotation (articulation) for the axle to prevent any binding. I guess the question is at what point do they reach their limit. Ibuildembig... correct me if I'm wrong! ....EXCELLENT THREAD! Been subscribed from the start.

Correct, but what you have to realize is that I am going for stability and axlewrap prevention, not all out suspension travel. I have added another component to these bars before that allows full use but isnt as strong. Basically what I do is put another joint in the front and make a shackle...this way it will float back and forth. I'm trying not to do that with this one because I'm trying to keep everthing up nice and tight in the frame and that would be another consumable part that I don't think is necessary for this particular project. Ultimately dad will make the call on what he thinks is an acceptable amount since its his rig. I did use the big joints though, just in case he wants the shackle mount....hmm just had a thought, maybe I can engineer it where he can have both....have to think on that one.

Here's what I did last night:

Since the explorer's brake hoses bolt on the back of the perch I decided that would be a good idea for this. I took the perches I cut off and cut the locater plates out of them, blasted the rust off, and welded them onto the bottom of the new perches. I am using a passenger side explorer line on the drivers side so that bracket had to be welded upsidedown to achieve what I was going for. Then I removed the vent tube adapter from the 8.8 and compared it to the stock D35 one. I was happy to see it was the same thread pitch, so I got my new drop brake line and screwed it into the housing with the d35 fitting. Now all I have to get is a 1 foot and a 3 foot brake line and the brakes will be done...cheap and easy. I'm not gonna mess with the E-brakes until I get it hung back under the jeep.

Looks like I found my how to for the spring over setup. This could be a dangerous thread if I get board on a rainy weekend this summer. Keep the pics coming, very helpful.

Nice work and I like that wish bone setup.

Thanks man! It would have been done by now, but I have 3 other rigs in my shop that I am working on too, plus trying to get stuff ready for the swapmeet this weekend, and working on my basement too

I plan on getting back on it tonight....parking brake shoes look like a pita to replace but it has to be done. When I get them off I am gonna look at the lever that makes them work and see how I can modify it to work with the jeep ebrake cables. Once I get that worked out I will get pics

Yeah not good lol.....I modified the 8.8 brake bracket so the jeep cables would snap in it and since I had to bend the bracket 90 degrees I have to put it in from the backside and to do that I have to remove the backing plate, thus removing the axle shafts. I popped the cover and removed the pinbolt that holds the pin in the carrier or so I thought. After about 10 minutes of beating on the pin I realized the bolt had sheared off and thats why I cant get the pin out (too many beers perhaps lol) So, now I borrowed a special drill out bit from a buddy and I plan on doing that tonight.

Not worth a crap his bit was junk so I have to get ahold of another buddy to borrow his. I have been working on his winch plate instead...took a TJ one and modded it to fit a YJ.

Anything less than 13degrees would be acceptable. If your running a dual cardan(cv) drive shaft any thing under 26

I think the second pic on the page before this shows the pinion angle but I will stick a protractor on it again to make sure. I decided to do the lower shock mounts off the wishbone bar, so I did that last night but forgot to take pics

I had a good day yesterday! I forgot the cam but I will post pics as soon as I can. I got the parking brake apply arms modified and installed, new parking brake pads on, new rotor/brakes installed, rear shock mounts welded on and shockes installed. The only think I have to do now is the brake line drop, the vent hose, and wait for the yoke to come in so I can button it up. I'm also thinking about modding the diff cover since it looks kinda chincy to me.
