Stop having a bearing in the case (5)
I believe the answer is:
cease
'stop' is the definition.
(synonyms)
'a bearing in the case' is the wordplay.
'a bearing' becomes 'e' (East, a compass bearing or direction).
'in the' is an insertion indicator.
'e' placed inside 'case' is 'CEASE'.
'having' is the link.
(Other definitions for cease that I've seen before include "Discontinue" , "Come to an end" , "Stop, give over" , "Stop, terminate" , "Culminate" .)
