0.6250 18tpi Tension Capability (lb) 36524 Shear Capability (lb) 27920
0.7500 16tpi Tension Capability (lb) 53408 Shear Capability (lb) 40200


All of the old TREs were single shear, and smaller. I'm sure someone here can and will tell me my logic is full of shit, but if I do shear the drag link bolt...



I will reassess wtf I'm doing...

You are right heims are stronger, but not 'legal' and your rig will see some street time.
IMHO safety washers would be a good idea.

I'm not familair with safety washers, so here's what I came up with.



And this



I'm suspecting this is the application you're thinking. I would also imagine, you're only talking about the tie rod to drag link rod end. The others are trapped under washers, and I am trying to inhibit rotational motion on the tie rod.




Which brings up a point, is there a proper method for using rod ends in a single shear application? Does the nylon side go toward or away from the mount, or it makes no difference?

At this point, I'm going to run this set up. I have all parts installed, and wired in, and the handleing, so far, has been very good. For me to go cross over, I have a bunch of dicking around with finding the right pitman arm.

I have no interest in hi steer, as I'm not trying to clear anything like springs, and the I think the tie rod is high and tight... enough for my needs.

I was thinking my set up was a cross over, so I did a search for steering type and came up with Billavista's write up. Its a good read on steering set ups.

Wooo hooo!

I got to wheel today and get some idea how this thing is going to work.

First, it is great on the road, steers and corners very well, and very smooth vibration free ride, I can even take my hands off the wheel and it keeps going straight.

This was more of a light trail ride with 3 Scouts mostly going over old logging roads.





The hill here is steeper than it looks with loads of diagonal bar ditches to prevent any momentum. The Scout articulated very well, and nothing broke or fell off.

I need to keep an eye on the power steering, I seem to be generating lots of heat, even with the aux cooler.

All in all, the rig worked well and I made it home...

Buck, a safety washer in a single sheer application is a large finder type washer a top the rod end to insure if the joint fails the rod end will be contained. Hope that is as clear as mud.........Robert

Thanks Robert.

And here is the Video I promised. This is kind of a "watching paint dry" video. This was the first day of having the hubs in, and I was really interested in not trying to break anything.

YouTube - Suspension Test

At about 1:50, the camera is getting the 2 wheel drive front end lift I was concerned about. It was not a design objective to create one of those bouncing low riders...

it looks like it rides pretty dang smooth.. is it a little higher in the front then the rear?? will raising the rear a inch or a little higher rear spring rate help keep the nose from lifting or rear from squatting?

It does ride dang smooth

It is a little higher in the front, for a little while. I'm running 14" colis in the rear, and I bought some 18", which should be here this week. The 18s are softer, which will raise the real about 2", and will allow more down travel in the rear.

The lifting is really only in 2wd. in 4wd, the whole rig raises, but not as much. FOA shocks sent me some parts to help with the lifting, and I'll be doing that in my spare time.

Thanks.

I wanted to raise the rear to level out the rig. I am running 14" 275# coils on the rear, and I picked up some 18# 250# used.



I thought I would just put the Hi-lift on the rear bumper and loosen the retainers and poof, put the longer ones in and be done in about 15 minutes.

You'll never believe this, but it took longer...

and there's a new issue.

I knew there were problems with the shocks on the rear. They were too short for full droop, and too close to the cluster mount I made, and I punched a hole in one shock and over extended and blew the other shock apart.

I thought I had no shocks, but I drove the scout home with no rear shocks at all, and with the new lighter springs, it was a bouncy ride.

I also noticed my springs were leaning to one side, so I measured my rear links, and believe it or not, they were not the same length. Both uppers are now the same and both lowers are the same, and the springs don't lean anymore.

Here's a pic of the 18s installed.



I'm either going to mount the correct size shocks slanting toward the center, or I'm going to make a hoop to bolt to the outside of the frame and lean the top forward outside the fram and towartd the front for the top mount. We'll see.

I do like the rake of the rig better with the longer springs, Can't wait for shocks.



More later...

You know, it seems like these projects are never done.

Well here is a "Big Pisser" update...

Copperhead pointed me to a new thread about Ballistic bushings. There are still people having failures with the original light gray bushings in as little as 1 day.

I checked mine with a pull on the link test and my upper link on hte passenger side had movement.

I pulled the link and who would have thought.



I have about 300 miles on these. In case you can't see. the inner metal bushing is designed to be a press in fit.

I emailed Ballistic (after hours) and had an immediate response from Jeff. We went back an forth a couple of times and the result is I ordered Ballistic Joints and will return the bushings for credit. It will take longer to get the replacements than I would like, but so be it, this will eliminate the issue for me once and for all.

This is a big pisser, but for me, Balllistic met the problem and resolved the issue to my complete satisfaction.

Are you still going to run both upper links with the joints and have no bushings in the front links? Any luck on getting your front end to not lift in 2wd? Does it lift in 4wd? Mine is doing the same thing. Haven't had it out wheeling yet. That will have to wait till the end of the month.

I am going to run both for the time being. So far, the setup is outpreforming my expectations, so I'll let it ride... I may try 3 links sometime.

As a matter of fact, I just got in the rear shocks to go with my 18" springs, an I a looking forward to seeing what happens.



I have abandoned my first the rear shock setup I did with the 4 link, and I'm adding a shock mount to the lower link mount and running the upper inward to the stock upper mount. I have been running Rancho 5000s on another rig, and would had again, but I looked at the Doetsch 8000s, with larger shaft (and we all know a larger shaft is better), and a built in bump stop. The shocks happen to be stock height 97 F150 rears with 11" travel.

For some voodoo reason, twisting up the rig looked like I have tons of wheel travel with about 6" of shock travel. I'll be welding the lower mounts on this weekend and we'll see if rear shocks help.

I think It will still lift in 2WD, but 4WD is much better, the whole thing raises evenly a bit.

I have not installed the FOA fix in the front end yet, so I don.t know how that will help.

2 updates in 1 day...

I got the shocks mounted, Yoohoo what a good ride

Still have the lifting front end issue, but even with the 18" 250# coils the body roll is not too bad at all. the ride is smooth and plushy and it just seem to suck up the bumps.

Why yes, my Scout hosts yellowjackets in the fall and mold in the winter. It starts every time, but has a sick tranny that I have not been motivated to fix yet.

Well finally an update...

I had to gather the motivation to replace the tranny for the 3rd time in 500 miles, but I did get it installed and actually wheeled.

Everything flexes well and is stable but I do need to figure out how to stop the links from rotating, and changing lots of angles.

Here is the right side.



and the left side



I'm thinking about a couple of options, weld a DOM bushing at the axle end of the lower link, and another is invert the links, putting the long link from the frame end to the upper hole on the axle and make the short link connect to the lower axle mount.

Any thoughts?

Eliminate the joint at center of the link. Weld the tubes together. A radius arm doesn't pivot in the middle.

I had the same problem during mockup. I replaced the heim on the rear of the upper link that attaches to the lower link with a urethane bushing. though mine hasn't left the jackstands I feel confident that it will resolve your problem. you might even be able to ditch one of your upper links as i did.
