Might sound weird but that's what it was, he stripped the front, the pins looked fine so he cleaned and greased everything and the problem was gone.
You never know?
Quite agree, my old +8 that had stood around, before I got it, for 3 years and only did about 500 miles in that time had king pin issues. When I stripped them down could see where the bushes had started to cause cross metal corrosion and a lip was there. Basically they were knackered through lack of use. So I can completely understand good old stiction issues at different heights.
