What is the best steering for my Jeep Wrangler TJ?

From what I can gather, Carl Jantz has a sold reputation in the 4X4 community. I don't know if I would go so far as to say it is 100% BS.

He's somewhat prominent and maybe most known for the Jana 44. That's about it.

And to be clear, I am not arguing with anything you guys are telling me, I am just asking the questions I have and exploring the options. Like I said before, I am a rookie in this area. But each time I have brought this topic up, I get a different expert opinion, and a lot of them differ drastically from each other.

To answer a question about why I am considering looking to change what TJ engineers have created, well just because I am going to make changes to the Jeep that differs from what the engineers were creating. I plan to put about 3"-4" lift and 35" tires on the Jeep. This is mild by some peoples build, but far from a stock street only wrangler. So I am just looking around to see what works and what does not. I do have a mild case of death wobble right now with a mostly stock 2006 TJ and 45,000 miles. I put a 1.5" puck lift on the stock Rubicon and the tires are currently 265/65/16. Just that little bit of a change has already caused problems with the death wobble resistant Haltengerger design. So I started looking at fixes.

I have no love for Carl going back a very long time and I will leave it at that.

There are way too many TJs running around with 4 inches of lift with stock location track bar and Haltenberger linkage successfully to necessitate going away from the design. What you need to do is read up here on the diagnostic basics like doing a dry steering test, checking your alignment and take the time to fix what is worn or out of adjustment currently.

You mean this one?

Yep, that one.

At some point for the TJ, I'd like someone to explain why or how that is actually something worthwhile. If you are taking out the ring and pinion often enough to justify that gear set, you really should be considering a larger axle.

If the presentation is based upon a flawed premise, then the presentation is itself flawed. They are both the same level of flawed since they make presumptions not in evidence.
Here is a non-greaseable Spicer u-joint. It does not have the same seals as the supposedly superior versions in the video. It does not have a separate thrust bearing. That and only a fool can't see that there are spaces between the needle bearings that will let any amount of grease you wish to pump in find a way out. If there were not spaces due to them being round, they would never get any grease to spin in or prevent wear. Also, just because the thrust bearing is not separate, that doesn't mean it isn't accounted for as evidenced by the raised area machined into the end of the cap.

That is due to what you see in the two videos. Each is based on a flawed premise yet presented very authoritatively. That means each has a reason to base their beliefs on to develop that opinion, yet each is highly flawed.

Learn how to do the steering tests to diagnose faulty, worn, or substandard parts and replace as needed. No need to reinvent the wheel whatsoever.

Helps keep you from breaking pinion shafts when you run those 1350 shafts everyone says you need.

What I don't understand is why the haltenberger linkage not used on the newer jeeps?

Or why they switched from it to inverted T on the Dodge and Ram pick-ups. My steering went from nice very pleasant to drive to a horrible vague on center constantly correcting to stay in the lane piece of poo after they did my steering recall.

Another place which has a "solid reputation" is Tom Wood's Custom Drive Shafts. When I talked with Shawn, he recommended the greaseable U-joints over the non-greaseable, at least for my particular use. I figure he just might know a thing or two about driveshafts and U-joints. :)

You will have to ask the same folks that even after bringing out an all new generation of axles continue to call one of them Dana 35.

There is little wrong with greaseable ujoints as long as they are greased. Problem is that they need to be serviced every 3000-3500 miles and most people now days are not doing that.

Which is the only reason I tell folks to get the non-greaseable. Folks don't grease them, the non-greaseable last longer.
 
Tom Wood’s recommends every 6000 miles, or with every oil change, or whenever you run through a lot of water and dirt – and you have to grease the cardan center ball anyway, and possibly the slip yoke.

I figured that if I had to grease the center ball anyway, I could do the U-joints too.

But I must admit, non-greaseable joints would probably outlast me.
 
I sure would not. I know Blaine already knows this but for those that do not:

Those flatter angles will help with bump steer in the short amount of suspension travel typically seen for highway driving, but the moment you start pushing things past that the disparity of length between the track bar and drag link will rear its ugly head. Then add on top of that the side effects the short track bar. Everything crashing into each other like driveshafts into exhaust, shocks into mounts, and the always delightful coil twang if you are not running coilovers(which will be a pain to fit as well). Also there is a question about the relationship between the front and rear track bars and how the chassis reacts to the difference in distance it is pulled or pushed throughout the range of travel if they are too different in length.

I found an issue here. The push pull effect I have it slightly. I’ll measure the rear. The front is out 1-7/8”

They should last 100,000 miles. I’ll take that way over greaseable.
 
Posted this in my build thread but here is a OEM Spicer greaseable after 4000 miles. This is why I recommend greasing every 3500 miles and there is no such thing as over greasing a ujoint.
