Stomach or shoulder (4)
I believe the answer is:
bear
I believe this clue is a double definition.
'stomach' is the first definition.
(both can mean to tolerate or endure)
'shoulder' is the second definition.
(I've seen this before)
'or' is the link.
(Other definitions for bear that I've seen before include "Tolerate - carnivore" , "Give birth to - large mammal" , "Shoulder - stomach" , "Carry, convey" , "Go" .)
