Pictured torque converter (TQ) hub maybe worn. In your March 1st post you thought that bronze bushing inside seal looked OK, but maybe it's allowing TQ hub to move around causing seal leakage. To replace this bushing requires removing 8 bolts on pump plate, using a puller, then disassembling two clutch packs before being able to access the pump gears and bushing behind pump gears. I think you can get the $3 bushing from Makco (link below). Also AWTEC in Michigan is selling remanned AW50 transmissions with TQ for $375 + freight on eBay.
Regarding crankwalk, Saab had a problem with ATF coolers plugging, which increased pressure of TQ on crankshaft causing crankwalk. Lever crank pulley with 2 flat blade screwdrivers 180 degrees apart to pull crank to passenger side. Set dial indicator on pulley or big end if you've got tranny out, push pulley toward driver side, and check indicator. Haynes manual says 0.08 to 0.34 mm (0.003 to 0.013 in) is allowable.
