Squeaky front end

Over the last few days I've developed a squeak from the O/S/F of my hawk when i go over a traffic clalming sleeping policeman (from the car - not the Policeman).

It sounds rubbery and squeaky rather than a knock. Suspension works fine and appears smooth rather than notchy.

Any ideas, are they prone to dodgy ARB bushes?

Over to you for your advice, ideas, experience and knowledge.
