Front end issues

I have a 91 YJ with a 4.0, boomerang shackles, 4" lift, and 2" body lift. These have all been on for a little over a year. recently i have developed a clunking sound in the front end when i turn the wheel almost like one of the steering componants is hitting or binding on another. Also my Steering is a bit squirly. I have replaced just about everything on the front end. New draglink, tierod ends, wheel bearings, bushings, steering stabalizer, even the steering shaft and the steering column bearing. I have gotten under the jeep and looked for the issue as well as had others look while turning the wheel no one can see where the noise is comming from. The only thing left to change is the gear box. This is an expencive part and dont want to swap it out if it couldnt be the issue. So my question is will the gearbox make a clunking sound as described above if it is going bad?
Please advise

Based on the mechanics of the steering gear, I certainly suppose the gear could make a clunk. You didn't mention if you checked the ball joints or not. I had my draglink to pitman arm connection come loose, the taper wasn't fully seated and it would clunk when I turned. With the jeep off, and the key in and ignition unlocked, have someone gently rock the steering wheel back and forth while you put a hand on each TRE. I could feel the clunk when I put my hand on the pitman arm, cranked down the nut and it was good to go.

The ball joints have also been replaced. Upon inspection everything seems tight. Are there torque specs on the tie rod ends and the pitman arm?

if you still have the track bar, it could be that too... I've had them clunk when turning when the ends were going bad.
removing the bar solved the problem in my YJ, and replacing the bar solved the problem on my old XJ

It's definitely a klunk. Not a klank or a clink

Check the bearing at the end of the steering shaft near the fire wall

I have tried everything. The only thing on the front end that hasn't been replace are the track bar bushings, but the track bar is not loose. Other than that the steering gear box has not been replaced. Like I said Everything else has been replaced wheel bearings, bushings, ball joints, right down to the intermediate steering shaft.
I am at a loss. I really don't want to spend the money on a new gearbox if there is not a possibility that could be the culprit.

Take your trac bar off and see if the noise goes away.
The rear trac bar is notorous for coming loose too.
You could tell if it was the gear box by putting a screw driver up against it, put the handle to your ear and have someone turn the steering wheel back and forth.

This has been replaced as well. there is still a little play in it, I can wiggle it around slightly, How much play should there be here?

I, and a few others, have mentioned your track bar(s), but you only stated "it's not loose"... is that going by grabbing it and trying to shake it? because even if it's loose, it might still FEEL tight trying to wiggle it.

we're suggesting you REMOVE the track bar (even if you hate it, just try it temporarily) and see if the noise goes away. if the noise is still there, then disconnect the sway bar (you don't have to remove it, just tie it up out of the way after it's disconnected.... in addition to possible track bar bushings like I mentioned, it COULD also be part of the sway bar (end links, bushings, etc) making the noise.

Did you get a pitman arm sized to compensate for the lift? Did you get relocators for the track bars to compensate for the lift there? - If not I'd bet the stresses from having screwed up geometry in them would wear things out (as if the stresses of a track bar on leaf springs aren't bad enough). As far as I know the joints in the steering shaft should be tight, no slop.
