Default New Steering Fab- criticism welcome

So, in my ongoing effort that will no doubt be described by some as polishing a turd, I am building some new stuff for my steering.

First up was an idler arm from total chaos. Very nice unit, will have to notch the frame for it to clear. Haven't gotten there yet.

This weekend I bent a tie rod, which was annoying and lit a fire to get me going on a project I've had laying around for some time.

Essentially, the challenge is, the tie rods on IFS cannot be straight, or the steering binds. Thus, as you will see in the stock units, there is a bend.

So, here is what I've concocted.

First up, I took two pieces of 1/4" wall DOM, 1.5" OD and welded them as so. I then took a 3/4" x 16 grade 8 bolt, and cut off the head and shoulder some. I then took a piece of 1/8" Wall 1" od tube, and cut it to size. I drilled holes in the sides, and then put the bolt in, welded top and bottom, and two rosettes on the sides. I then smoothed it out with a grinder, and, after drilling two holes in the 1.5" tube, I slid the bolt and 1" tube inside, and again, welded top, bottom, and rosettes on the sides. This was the result:





I then reasoned that this would not be strong enough. I then put a front plate of 3/16" on the front, and welded to both tubes, then two plates top and bottom, again welded on all sides to both tubes, and then an end cap, just to keep out water. I then welded a 23mm RH thread insert into the other end and ground it to clean it up.

Lastly, I made an adjuster sleeve with a 3/4" x 16 RH thread insert on one end, and a 23mm LH thread insert on the other.

As you can see from the assembled pics, I'm using FJ-80 rod ends in both sides that attach to the existing steering.

NOTE: Nothing is threaded on all the way. Obviously, not nearly that much thread will be sticking out.





Thoughts? Areas that look bad? Not a ton I can do about it now, but we'll see.

The obvious weak link to my eyes will be the 3/4" threaded bolt. It all looks beefy but that looks to be the same size as what bent before.

The first pic scared me but even before I scrolled the screen on my Droid I thought 'Give Isaac 30 seconds & it will be hell for stout '. Sho'nuff.

When will frankstein come alive?
I agree with UB, that center section is still a week link, but if it always moves that in a straight line, then all should be OK. Will it fit where it is designed to fit? and move the wheel back and forth with out binding?

Well, I dunno.

The pic above does not quite show things as they will be. It is designed to have very little thread showing when it is the proper length. As it is shown in the picture, both my new one, and the stock one are WAY too long. I just stuck them together to show it, and didn't feel like running the threads all the way in.

Robbie, It sort of moves in a straight line. It is always being pushed or pulled on along the axis, however, because of the bend, I imagine there will be some side load, though I don't know how much. It will also move up and down as the suspension cycles.

Anyway, I haven't gotten it on the truck to check clearance yet because it was way, way too hot last night to handle without channel locks and vise grips. We'll see.

I am concerned about the 3/4" bolt now. I dunno if it makes a difference that most of the threaded bolt will be inside the adjuster or not?

Interesting, sooner or later there will be no stock parts on your rig

Sorry to be a critic Isaac! It just seems that that smaller (not small) 3/4" threaded section is in the exact same place that the original rods bent and close to the same size.

why did you build it with the bolt in the middle? I'd remove that and you still have adjustability with the length of the rod.

You have nothing to be sorry about. I want feedback good and bad.

I am concerned about it. One thing is that the original bent at the bend in the tie rod, and carried through to the threaded area, at least thats what it looks like to me. I'll snap a pic tonight.

However, I may start over and use something like 7/8 hardware. We'll see.

Sorry wes, I'm not following you there. What do you mean by "in the middle" and I don't understand which part you'd remove?
