I've not had any experience with Antigrams, but plenty with Ratchets. If it is indeed a 17mm Ratchet, then it is absolutely imperative that you have all 3 pawls and springs. The outer end of a Ratchet driver can move a bit on the roller bearing inside it, this is by design. By running 1 or 2 pawls you are allowing it to running eccentric (off-centre) and rub places it shouldn't do so (namely the roller bearing cage) as it rotates, which would account for what you've found
