GTX, there is a valve at the top of the box where the pressure line attaches. It’s a plate with two mounting bolts. If you loosen the plate bolts the plate can slide a bit…which makes a BIG difference in how the steering pulls one way or the other. You adjust this with the wheels hanging in the air, engine idling. Many people don’t know about that adjustment. Im familiar with the adjustment you mention. Ive had the front in the air and running. ...it doesn't turn . Nor does it pull driving down the road

When adjusting that valve body (on top of the gear box), I highly recommend not just having the front wheels off the ground, but to have the front wheels removed from the spindles. You want as little friction (weight) as possible so to assure the power assist of the left-right-left-right action is at a minimum of the gear box.... IF you wanted to go a slightly different and better route, you could alternatively disconnect the Pitman Arm from the steering link cross-arm (letting that hang)... again, reducing all possible friction from the gear box. That's how I've done it in the past... best results!

I don't recall how much movement there actually is, but I'd think there is more than 0.02"... perhaps maybe 1/16" for and aft?

Sounds a little confusing... when the engine turns off... there shouldn't be any further assist in either direction.

Otoh, there shouldn't be any movement when he start the engine.
This might be a 2 angle problem.
One, incorrect adjustment of the centering valve. Explains the movement of the steering wheel engine running or not
Two, might be excessive friction in steering joints. For example a frozen tie rod end. Or, my hunch, too much preload on the sector shaft.
A bit of work but, what happens if you drop the pitman arm? Does the steering turn by itself if you start the engine?

Air in one or the other chamber is a possibility.
The long pitman should affect both directions equally.

Hopefully, along with the "long Pitman arm"... you are also using the long Idler arm... simply a ~1970 C-Body (Fury) idler arm. Sellers often refer to this as the "fast ratio IDLER ARM"... its simply a longer idler arm that should've been factory installed on the E-bodies having optional "Fast Ratio" power steering which comes with the longer "FAST RATIO PITMAN ARM". IF only the longer Pitman arm is used, then the turning radius is different Left vs Right... it was a factory mistake/oversight on those E-bodies with the optional Fast Ratio power steering. No company (Firm Feel, Hotchkis, PST, others, etc) ever developed a "Fast Ratio IDLER ARM"... it has always been and always will be simply a ~1970 C-Body (Fury) idler arm.

mevotech #M525940 - $27.79 moog # K7014 - $50.99 rock auto prices as of a few minutes ago. they also give delphi #TA593 and centric #62063005, but list those numbers as out of stock. these parts may be available elsewhere, but i didn't check. [these are the 1970 C-body idler that Mitch mentioned above]
