Bond suspicious about angry tirade (8)
I believe the answer is:
warranty
'bond' is the definition.
(thesaurus)
'suspicious about angry tirade' is the wordplay.
'suspicious' becomes 'wary' (I've seen this before).
'about' indicates putting letters inside.
'angry tirade' becomes 'rant' (I've seen this before).
'wary' placed around 'rant' is 'WARRANTY'.
(Other definitions for warranty that I've seen before include "Quality guarantee" , "Written guarantee" , "Free repair document" , "Certificate" , "pledge" .)
