Does anybody have experience overhauling the DA PD-7810 pedal?

I've got significant spindle play on both pedals and have disassembled, cleaned and reassembled one of the pedals, but there is still play. Outer bearings seems fine (grease still clean), so I removed the circlip for the inner bearings and cleaned the dirty spindle assembly as well as added new bearings (17 pcs).

Playing with the locknut adjustment did not make a difference. Is there another wear part I need to be considering?
