HELP Windshield Wiper Retainer Bushing

Here's my take... One bushing fails, always the same one, it has been in service 30 years or more.
That one or all 4 bushings are replaced. After a year or 2 depending on how much rain you get,
the same bushing fails again. Since it didn't last 30 years like its predecessor, the quality of the replacement part gets the blame.
If you find yourself replacing the same bushing frequently, have a closer look.
You'll find the root of the problem is in the left hand pivot post assembly.
Good luck
