Knocking noise that increases with road speed

Problems posting from an Android device?

There's a known problem.

Is it new and has any work been done it recently?

Does it go away if you declutch?

Is it affected by cornering?

...

Then I'd feel by hand for play in the prop shaft and drive shafts.

And check the engine and gearbox mounts.

And the wheel bearings and discs.

And look for clearance and witness marks on the de Dion ears.
