Thoughts on Durango replacement box

I have an AGR superbox 2 that I HATE it’s now loose and no amount of adjustment seems to work following the AGR instruction. I don’t like the reduced turn ratio and it won’t return to center. There’s little info as to “Durango” replacement boxes. What I want is a durable steering box with the same or higher turn ratio, it’s downright squirrelly with the AGR. It was a decent handling Jeep before I put it in but the old one was worn out and leaking.
Any thoughts would be helpful.

What year is your Jeep? I think the steering box changed in 03 or so, and the swap is no longer direct for 03+

Mines a 98 so that’s not an issue

Dont get a durango box. The lower sector shaft rides on a bushing rather than a bearing (read:faster wear). PSC is popular and has reputation, but is out of the budget for most. There is info out there that an 03+ Chevy S10 steering box would work, but the info is pretty lacking. I had one in my hands to replace my OE box but ultimately decided against it. LARES Rockcrawler from RockAuto is a durango box with the bushing removed and a bearing put in its place, but at $300, it is also a hard pill to swallow. I ended up going the Reman'd route with a box from NAPA. $175 with a $222 core charge. But only took an hour or so to swap in. So far it has done just fine.

Are you running larger tires that a stock unit is not an option?

I did it with my 99 TJ and had no issues at all.

I have 33x12.50 tires, the previous article on the Durango box cleared things up for me. I’ve had issues with boxes from Napa being mis adjusted or just plain leaking, the rock auto route is an interesting one, there’s an ACDelco one on there for 220 shipped. I’m going to check my (caster?) angle too to make sure nothing has moved but I don’t believe it has

I'm not saying there's nothing wrong with your AGR box but poor return to center is normally from an insufficient caster angle. What is your current caster angle?

When you say loose steering, do you by any chance have an aftermarket high-steer steering kit installed?

I am going to have to check actual caster angle, before the new box it returned to center, after the new box it did not. I have a Rusty’s cross over steering kit and an appropriate drop pitman arm to match the drag link angle to the track bar angle, I think it’s 4” but I’d have to go measure it.

That steering setup isn't helping anything...

Rusty's steering system geometry is probably causing 90% of your steering issues. Seriously. You and your steering would be a lot better off going back to the factory geometry with a good quality heavy duty steering kit like Currie's which would restore the original factory geometry. The TJ's steering geometry is actually superb, really, and only in very unusual configurations would changing that geometry be a good decision.

Currie's steering kit reputation is superb. Rusty's is, well, not nearly as well appreciated. And of course all of this being strictly my personal opinion.

Not trying to be argumentative here, asking seriously. what’s wrong with Rusty’s? It was supposed to eliminate bump steer, I’d say it did that. I hear crap about Rusty’s but have always felt their products to be well made. I bought their control arms and track bars. Their sturdy and don’t appear to have deteriorated, also they eliminated the relocation bracket, which I’ve always felt to be a weak spot.
