Moan making good thunderous sound (7)

Ross

I believe the answer is:

grumble

'moan' is the definition.
(I've seen this before)

'good thunderous sound' is the wordplay.
'good' becomes 'g' (abbreviation).
'thunderous sound' becomes 'rumble' (I've seen this in another clue).
'g'+'rumble'='GRUMBLE'

'making' is the link.

(Other definitions for grumble that I've seen before include "Express dissatisfaction" , "Complain, protest" , "Moan" , "Murmur with discontent" , "what Meldrew does" .)
