Knocking Noice Morning speed ramp DB9 Volante

[sharky67]

When There is really cold weather (first trip of the day) - : I drive over a speedramp not far from my house and the car makes a knocking noise from the front when going up and down the speed ramps.. but then after a few miles when i get to a speed ramp again its fine and fine for the rest of the day even going home back over the speedramp.... any ideas.. Its not the car scraping ... seems like a knock from suspension or something..

...The last people to touch it was to have the tracking done.. could it be related..
