Driving force may be arrogance in front of team (8)
I believe the answer is:
airscrew
'driving force' is the definition.
(aircraft propeller)
'arrogance in front of team' is the wordplay.
'arrogance' becomes 'airs' (to 'put on airs' is to behave arrogantly).
'in front of' says to put letters next to each other.
'team' becomes 'crew' (crew is a kind of team).
'airs'+'crew'='AIRSCREW'
'may be' acts as a link.
(Other definitions for airscrew that I've seen before include "means of propulsion" , "Plane's propeller" , "whirling blades" , "Part of plane" .)
