Locate stand-in turning up in row (4-2)
I believe the answer is:
bust-up
'row' is the definition.
(bust-up is a kind of row)
'locate stand-in turning up' is the wordplay.
'locate' becomes 'put'.
'stand in' becomes 'sub' ('sub' can be a synonym of 'stand in').
'turning up' says the letters should be written backwards.
'put'+'sub'='putsub'
'putsub' back-to-front is 'BUST-UP'.
'in' is the link.
(Other definitions for bust-up that I've seen before include "Serious quarrel or fight (B, not D)" , "Quarrel, possibly ending a friendship" , "disagreement" , "Serious altercation" , "Serious quarrel/fight" .)
