Update !! We'll all front was stripped and the front suspension was all greased etc. from what I can see the builder put it together thinking that the nylon bushes were enough for the suspension to pivot on and assembled it with no grease ????? He also tightened the pivot bar so tight that even when the shock was removed the arm still needed a little encouragement to move up and down (I had to use a breaker bar to undo nut on pivot) so all redone and a 3mm plate temp put on till I find or am happy with a better way
