Wheel connectors (5)
I believe the answer is:
axles
'wheel connectors' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for axles that I've seen before include "Wheel shafts" , "Rods between wheels" , "Shafts of wheels" , "Shaft on which wheels rotate" , "They may be involved in turning" .)
