Well, the long running ( 16 yrs ) saga of a slack steering effort finally revealed itself ...... Thought it was A ball joints ( replaced every one over those years ) B steering box slack ( tried adjusting it to no avail ) .. C Wheel bearings , trunnion bush . etc etc until , looked at Drop Arm on steering relay welded on - no pinch bolt ! Quite slack at this point . New Arm and pinch bolt , now tight as a drum . Thankgod 😕 ( obvs this got passed by 16 inspections by Vosa in my hands )
