Hey all,
Been tracking a small water leak after the rain last week. I've tracked it down to one of the wipers which is loose. Threw a 19mm spanner onto the nut on the outside and the nut turns fine but turns a bit, pops and then goes loose again (as though something stripped - I'm really really hoping it's not ha). Anyone who has had this apart have any ideas there?
Noticed the two wipers are slightly different also. The second image is the one that is loose.
