Be afraid of a noisy lug (4)

I believe the answer is:

fear

'be afraid of' is the definition.
(I've seen this before)

'a noisy lug' is the wordplay.
'a noisy' becomes 'f' ().
'lug' becomes 'ear' (informal term).
'f'+'ear'='FEAR'

(Other definitions for fear that I've seen before include "Qualms" , "Cutting edge" , "Apprehension" , "Be afraid of" , "Respect" .)

I've seen this clue in the Evening Standard.
