Hi, not an expert by any means but both the preload adjusters on mine can be turned by hand, again like yours they are not loose and there is some resistance but easily turntable none the less, I also had a major handlebar wobble when letting go the bars, a new front tyre seems to have solved it though, so not sure if the preload adjusters are an / the issue regarding the wobble.
