Henk,
Just saw your additional post made while I was typing. Seems like you may have two separate occurrences with overlapping periods. So a glitch with both bearings? Wondering if some additional block to block tension may be needed. Or perhaps to much pressure on the worm towards the ring gear is overcoming the axial tension, and you are again riding too much on the outer races. Perhaps starting a bearing purchase may be in order. I bought a pack of 10 the last time round so I would have extras at home to experiment with, or to see if one is better than another.
