Body of vehicle about to be put on ship (7)
I believe the answer is:
carcass
'body' is the definition.
(carcass is a kind of body)
'vehicle about to be put on ship' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'about to' becomes 'ca' (I've seen this in other clues).
'be put on' is a charade indicator (letters next to each other).
'ship' becomes 'ss'.
'car'+'ca'+'ss'='CARCASS'
'of' acts as a link.
(Other definitions for carcass that I've seen before include "Framework" , "Dead animal's body" , "Dead body of animal" .)
