My brother and I have the same E34 problems and I guess it is quite common as we’ve 3 cars all with the same and I’ve seen it on some I looked to buy too.
The left hand wiper (as sitting in car looking forward) is loose and rubs the edge of the bonnet. Open the bonnet and raise the wiper arm off the screen and there is an immense amount of play in the shaft where it goes through the mounting.
Is this as common as I think and is it an easy fix?
