Adjust, as car wheels (5)
I believe the answer is:
align
'adjust as car wheels' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for align that I've seen before include "Bring into line" , "Set in order" , "Place in a row" , "Straighten -bring into conformity" , "Arrange in a row" .)
