[TR] TR4A - Windshield Wiper Slipping

[G.D. Huggins]

All,

First of all, I am coming up on five years of driving the car after the 8 year restoration project.
The advice and help I got through this forum was instrumental to getting her back on the road.
Thanks again to all of you.

I am experiencing a new issue that I hope you can help with.
I replaced one of the windshield wiper mounts, and both wiper arms, during the restoration.
At first, everything worked great.
But now the wiper arm mounted to the new mounting “slips" when traveling up the windshield, but stays “locked" when going down.
The effect is that the arm eventually ends up on the bonnet, doing a great job of keeping it free of water!

I tried placing various things (teflon tape, rubber glove finger tips, etc.) between the arm and mount in an attempt to create a tension great enough to keep it from slipping, but to no avail.
My guess is that the splines in either the mounting wheel, and/or the wiper arm, have become quickly worn, but somehow only in one direction?!?

Has anyone had this issue?  If so, what was the fix.
If I replace the arm and/or the mount, what vendor should I buy from?  Avoid?



Cheers,
