Power steering rack failure modes 200 1992

Okay, I've experienced a few rack failures in 240s, ie, the leaking seals on the output shafts, the return lines popping off at the passenger side seal, and the input shaft seal leak.... But now I am stumped, I've got an issue where the rebuilt rack is sloppy, ie. the input shaft moves and it takes a bunch of movement before the output shafts move. This of course results in a very sloppy steering feel and on a crested road, I find myself having to saw the steering wheel back and forth rapidly to maintain a straight line. I have verified that that the rack has significant input to output "slop", the ball joints, tie rods, bushings, rubber strut mounts, and so on, are perfect.

This "slop" showed up very suddenly after bashing through a set of pot holes under heavy breaking (dry road and a few ABS pulses), so I am wondering if this may have been the culprit. Even the U-bolt mounts to the cross member are tight and the cross member to frame rail bolts are properly torqued with no evidence of slippage.

Final question, is this a known or "common" failure mode for the PS rack? If yes, is there an adjustment, or is it time for another rack? For those of you who know Mercedes steering from the late 80s, it feels like a fragged steering gear box.

Thanks folks... I think Raleigh is shaking this pup apart!
