My Duetto is making creaking noises since being put back on the road after a 18 month lay off due to renovation. Passed the MOT back in may. The noise is on turning (and on braking when going straight ahead) and I first thought it was the steering but it gets worse when the road is uneven. If I jack up under the spring pan and turn the road wheel the creaking appears to come from the suspension upper swivel joint (checked one side to date). No grease nipple so any cure or further tests I can do. Cannot see the connection with braking though.
