First, try to adjust for correct tension. When the damage is not too 
serious, it should be possible, to get the "knack knack" away, with a 
minimal lockup in straight position. 
A fast repair would be, to rotate both outer bearing rings for 90degrees. 
With a little luck, that might work for another 20.000km :-))

> what will happen
a loose and defekt stearinghead bearing negativly affects driving 
performance. if it is seriously damaged, you won't be able to get the 
correct tension as it would then lockup.

buy a new one including searings (dichtringe) and carry them with you. If 
you really run into trouble, we will change it "online" (ToM has done that 
recently :-). Of course, that will cost you a giant pizza :-))

> > Fork oil for Technoflex
According to the list in the Hein gerike Catalogue, it is SAE7.5 and air 
chamber 150mm. 
Personally, I recommend SAE10 and air chamber 105mm (like original). Both 
avoids "hit through" on rough driving (and you are a rough driver :-)), 
give you good feedback on-roads, but enough sensitivity for offroad. That 
worked well with WP ones, don't think, that the Technoflex are much 
different...
