Fiesta St Suspension Knock

[calmcdermott]

Ok here we go.

Had a knock coming from the passenger side front suspension for a while now, I've had the suspension stripped down and checked by 4 mechanics and everyone is baffled, it's not just me as they can hear it too (3 of the mechanics I personally know so wouldn't lie to me just to get the money).

Changed the suspension mount, checked the spring and strut, changed the anti roll bar bushes and drop links and also changed the bearing. Everything is tight with no play.

Best way I can describe is that it sounds like a hollow knock and sounds quite like well to be honest like me tapping on my iPad's screen whilst typing! It's over any little bump in the road and is driving me up the wall, any suggestions?

Plastic wheelarch liner loose & flapping about somewhere?

As above the wheel arch liner did it on my focus which took me a while to figure out where it was coming from

It could have come loose or as the wind is pushing the arch liner back, it hits the body panel at the top

Might be completely wrong but that's what it was on mine

Ok so update:

- Checked the bumper and wheel arch lining and secured.

- Changed the anti roll bar bush again, drop links changed last year, changed the suspension mount ensuring the bolt at the top is tight and also changed the lower suspension arm, it's bushes and ball joint.

So now I am completely and utterly confused! Could anyone suggest anything else?

Is it the spring rattling when the strut extends down into bumps most mk6's make this noise mine is pretty keen on doing it.
