Working on rehabing the electric wiper system on the truck. If you look at the first picture, I THINK there is a rubber bushing between the wiper arm (that connects to the wiper motor) and the stem that goes thru the opening in the cab. If you look at picture 2, it looks like I could put a screwdriver underneath where the wiper arm connects to the stem and just "pop the stem off of the wiper arm" and then be able to replace the rubber bushing.

If I pop the stem off, can I just press it back on after putting on a new rubber bushing?

Thanks

Can you pry the seal out without taking anything apart, then use a O-ring or cut some inner tube to replace it? Replacing rivets is sometimes a real job to get them right.

Joe;

I don't have a lot of mechanical experience to the point where I did not know I was looking at a rivet. I will examine more closely to see if I can make your recommenation work. Thanks for helping me see thru this challenge.

I moved your thread into the Interiors forum, where it is more likely to get the attention it deserves.

Unless the rubber is really deteriorated to the point of crumbling and falling out, it may be best to just leave it alone. My wipers are also from a 52, never been refurbed and they work fine.

It's likely a damper and not any kind of seal, just something to keep the linkage from rattling around. Maybe a good soaking in oil to soften it up will be good enough.

Don't use oil on a rubber piece, that will accelerate deterioration. There are products available specifically for rubber.

You might be able to stretch a small diameter o-ring into place that will fill the gap. It will need to be thin enough so as not to bind it up.
All that original material does is keep the rattling noise down. They still work even when that material gives out.
I just put some white lithium grease on the shaft and the articulating ball and call it good enough.

Good advice. Thanks, Carl

I dont know if you got this sorted out yet. If not, hopefully this will help.

Picture and comments help a great deal. Thanks.

Most wipers Ive seen, that knurled barrel that secures the wiper arm is held on with a friction fit pin. Yours appears to be more permanently affixed. It looks like the shaft has been peened to secure the barrel??
