Loose steering

Greetings team. First time caller here. New owner of a 1994 Suzuki Jimny Sierra Elk. Automatic transmission, 1300cc, RHD from Japan. Not my first JDM rodeo... we're one Toyota hiace, Toyota Toyoace, and Suzuki Carry in so far. That said, I'm still an unlearned student, humbling thyself to the JDM gods. God help me. Anyways... My steering feels pretty loose and out of control when I'm driving. As seen in this video, it appears that the steering rod needs replacing, maybe pitman arm too? Tie rods seem okay? Looks like I can't upload here, so putting in a google drive:  [MEDIA=googledrive]1T4smq8Vp52z2uulXpL6MMRH_utHfnM6u[/MEDIA] I'd be grateful for your thoughts on: what's going on; which specific parts to replace (attaching diagram with #s from Megazip); and if you have recommendations on where to source parts besides the normal channels (I'm in the US)?  Also, is it okay for me to continue to drive for the timebeing despite it feeling pretty loosey goosey? Noting this is a cross post across forums... seeing where I get the most action... cheers y'all!

My specific knowledge is more of the gen3 car but it's all much the same. There are a few things to look for with vague steering. First is to carefully feel for play in the steering box this can be done visually with a helpful friend moving the steering wheel while you observe the steering input shaft relative to the pitman arm there needs to be some slack around the straight ahead position as that's where it wears most and this can be adjusted via a locking nut on the top but don't take too much out of it or it will bind up as you apply more steering. Secondly confirm that the pitman arm is secure on the steering box output shaft it will be obvious when you give it a good shake with your hand, it shouldn't move at all relative to the shaft. Next is the condition of the ball joints on both the drag link and the track bar they again need observation for wear. It is possible to feel this wear by manually steering the road wheel it will be a click or clunk as you change the angle of the wheel obviously with the wheel supported in the air. After that the jimny is notorious for needing kingpin bearings especially when you have over size tyres. They are not always easy to diagnose in the traditional manner of observing vertical movements of the road wheel while supported in the air as they can rust solid, that said they will often cause the swivel to leak a greasy oily mess as when the kingpins go they take the inner axle oil seal with them. That said kingpins usually exhibit a very specific steering vibration at around 45 to 50 mph rather than just vagueness. Then there are the various bushes and general tightness checks to do like shackle plates and U bolts and confirm the condition of the leafs especially if it has been put to spring over axle as they don't like a lot of hard use it that's done. The long and short of it is of all the live axle vehicles out there the jimny does seem to be the most particular about having everything in the system be perfect for it to drive nicely, fortunately there aren't many components to change to get there.

The SJ is a bit wandery around the straightahead compared to the Jimny in my experience. 

All of the above is valid, I’d also look for if it’s got outrageously long shackles on it. On a mates that really didn’t help. 

Check all of it for play, but don’t expect too much! 
Ive got a drop pitman to go on mine (2”lift via OME springs) 

Its straight and stable up to 80mph or so
