Send you a PM.

Cool. I'm here too, in Topanga. I'll come get the boxes. There's got to be a good one out of 3 sets of parts.

OK. As feared, it's the everything causing the problem. Bushing is a little loose, bearings are junk, both heavy gears are pitted and, oddly, the small 2 tooth gear is loose on its roller pin. Net result - adding up all the small errors - is no good.

How do I find a spare box?

I'm going to pull it today. For experimentation sake I overtightened both the sector adjustment and the endplay to see if the slop left the building, with no joy. So it's either the bearings or the bushing and probably both. 

With everything overtightened I'm not sure there's enough play to make the wobble in turns....but maybe. Otherwise it's bushing time.

Alignment is done and good and tires are new and balanced. New front bearings too. No play in front parts anywhere. Idler arm busing new. Everything centered and lubed.

oh, the wear mode of mine was that the pitman arm shaft rocked in its worn bushing. it was barely visible but that's enough to make it very sloppy. i wonder though if it woudl cause a shimmy. 

pretty much all these boxes, the backlash is very low when the box is correctly centered, but a substantial amount of play/backlash off center. this is intentional, i forget the reason. the sector gear is cut that way.

the point is, the box must be exactly centered when the play is set (by preload with a spring scale, if i remember, but hmmm id have to RTFM). steering wheel centered, qhich requires good tie rod ends and good lower trunnions. and in the early americans, the steering linkage balls and sockets all OK. (that thing is weird. i think i know why it is like it is.)

there is no adjustment in this (or any) steering box... that's the end play adjustment. and it's gotta be set with the box out of the car or at least with the pitman arm not connected to the steering link. most boxes the sector engagement is a shim or cover plate thing.

it's an easy rebuild. the kits are NOS, but likely available as no one ever rebuilds them! lol. 

though the ratio is terrible and it's a spear'o'death, mine's thoroughly pleasant to drive, no slop, etc. and gear oil instead of grease works great.

Poop!  This one had water in it when I got it (48K miles) and it's notchy and won't adjust. Hopefully it just has bad bearings and bushing but I have my fears about the heavy metal, based on how it feels.

It's giving me a weird shimmy on slight turns over 45 mph, both ways. Feels like bad wheel balance but isn't. Nothing at all if pointed straight ahead. I guess it could be soggy control arm bushings but the box needs sorting in any case so it goes first.
