Remove some raucous troublemakers (4)
I believe the answer is:
oust
'remove' is the definition.
(I've seen this before)
'some raucous troublemakers' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'OUST' is hidden in the letters of 'raucous troublemakers'.
(Other definitions for oust that I've seen before include "Force out; supplant" , "Extract" , "Depose" , "Show the door to" , "Unseat" .)
