W124 E320 passenger seat crooked

[wolf_walker]

My Very Significant Other just noticed the passenger seat on the new to us 94 has a pronounced lean toward the passenger side. Oddly it seems to move with no complaint under all power functions, until the seat back side contacts the B pillar. I'll pull it out and see what I see, ring any bells for anyone? I'd expect it to be not-working some direction but it's fine. Front track, what I can see of it, looks normal, rear is obviously at different height levels.
