Hi
I recently had the windscreen replaced on my ford transit connect, And a couple of days have passed now and we have had some rain, i noticed a scraping noise when my wipers were on so i stopped to take a look. the driver side spring on the wiper arm is rubbing along the screen when in operation.
Can the nut be overtightened holding the wiper arm? should it be torqued to a certain value?
The nut itself is not loose which was my first thought thinking that the arm hadn't been secured properly.
