Adjusted, as a car's wheels (7)
I believe the answer is:
aligned
'adjusted as a car's wheels' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aligned that I've seen before include "Placed in the right relative position" , "Put straight" , "Brought into the correct relationship (with)" , "Dealing (anag) - straight?" , "joined forces" .)
