I had found it near on impossible to get accurate answers from the factory over the last 18 months when we were having a run of warranty issues on the car, yes, the faults were rectified ( in time), but nothing in depth explaining the cause of each issue. Quite frustrating.
Yes, I understand completely. You are not alone in this over the last 15+ years. It is another reflection of the "hard times" management policy on Pickersleigh. Those in control became very irate after PM's passing about the endless discussions on
eMog on how to sort errors occasioned by the ongoing flood of modifications and new models. Staff was strictly warned that offering information to owners could result in consequences. It was a great pity as the Works dearly needed the feedback and fixes. I took it as yet another reason to close the forum.
However, there is a new Management now with impeccable credentials. I am hoping that this new regime will be more interactive with the Community. They recently reached out on another matter and I responded. I just now sent a note on this issue, testing the waters so to speak. Let's see if I get turned down flat. (Fingers crossed)
Anyway, ref your Yellow arrow in the photo.. that is the Allan hex screw that passes into a splined wedge that clamps the wiper arm to the wiper spindle.
Yes. I understand and supposed that is was it is. I am not looking at this as a solution. Merely a way to relieve some of the pressure. If it is too tight it will not be helping the friction. (perhaps) In my case, in my Morgans and other cars, I have also lessened or increased the wiper/screen friction by altering the shape of the wiper arm..as well as changing the wipers.
As per Richard, Dave and Jons comments I will first thoroughly clean the screen.
Yes. That is the first thing. We need a clean base datum. BTW, do you have a little torque wrench at hand?
https://shorturl.at/gsGU4The internet seems to indicate that applying a screen coating could either improve or cause screen wiper judder..
That is too many variables for a generic cure at this stage.
[quote=Davetherave] I am still deeply suss of the fact that the wiper arms have side to side play at their spindle, the section of the arm that goes to the blade is pulled tightly to the wiper arm end cap by its spring, so the "play" at the spindle feels sprung loaded, but the fact that its there on all three arms may be due to design or poor manufacture..
Key observations. We could shortcut this solution if we can talk to the designer. Let's see what happens on that end.
Just as a thought for a test, if you spray the windshield with some soapy water the juddering should be gone if it is due to the friction of the windshield.
Thank you Heinz. Yes, that will additionally confirm that the issue is caused by too much drag at the windscreen/wiper interface.
