Would it be possible to eliminate the spindle play as a cause by using a tooth pick to poke some PTFE tape down the spindles (leaving a bit poking out so easily removed if it makes things worse!) ?
Hi Paul.. It does not appear possible to temp reduce the play at the fulcrum pin on the wiper arm. The fulcrum pin comes from and through the outer arm and then through the inner section which is part of the arms end cap that goes over the main spindle. The play seems to be in the clearance between the pin and its through hole in the arms end cap. So its blind to gain access to.
