Hi guys! My Dodge Minimotorhome is home! :-) I am very happy about it and now i can start check and change fluids, filters and repair some defects.
And now i need your help again.
During riding home yesterday the last 40 miles the weather got worse and i have switched on the windscreen wipers. After about 20 minutes the wipers stopped working. It is a mechanical problem.
The wiper engine is running but the bushing nearly the engine is broken. It's a big problem to get this bushings in Germany, but a friend of me is in LA now and would by the bushing kit, if i would send him the Chrysle/Dodge part number. My RV is a 1979 Dodge Sportsman.
The picture above shows the place (not my picture, only for understanding) where the bushing in my car is broken.
I think it makes sense to change all the bushings in the wiper likage.
Thank you for your help.
Chris

Well, your red circle is throwing me off. That looks square, and NOT like the bushings I'm used to replacing. Which are the white ones on the ends of the long rod. Those I know all about. Easy to find, and cheap.

What you have circled I am unsure about. It appears to need something different, are you sure that is not intended for a stud/bolt/shaft to connect to the wiper motor?

Thanks Eyeteeth. The photo is symbolic. the linkage in my Dodge is for´using round bushings. Sorry for confusion.
Another picture (don't know if it's 100% like my linkage) In the round circle is the bushing that is broken.

I wish I could go out and look at mine as I'm pretty certain they are the same. You probably want the Doorman part I linked to at Summit Racing. Not sure if the is an OEM available, but I have used the Doorman part in the past. The part that sucks is they don't break if you're not using them... and when you ARE using them... its because you need them... so you are pretty much guaranteed to be standing in the rain when you have to replace them.

Chris - eyeteeth is right, the bushings that usually need replacing are the ones on the far right and left in your picture.
I think a nut or screw on the motor shaft came loose or off, allowing the motor shaft to turn freely inside the linkage mounting hole.
The hole you circled is where the wiper linkage mounts to the wiper motor. See this picture at http://weblink.carqu........t.com/acl/?mfgName=REB&partNumber=40-394.
The silver metal part on the linkage in your picture is the wipers crank. It translates the rotation of the motor shaft into the linear (back and forth) movement of the linkage. (The basic action is similar the the crankshaft/connecting rods in your engine.)
The hole you circled has flat sides that mate to flat lands on the motor shaft. This is so the silver metal part of the linkage rotates with the motor shaft.

It's possible the wiper motor can turn when not connected to the linkage but lacks enough oomph to push the linkage. (In other words, the motor is wearing out.)

Sorry folks, I got error messages when I tried to post. When is did finally appear to work, I saw triple posting ... have sent message to moderator, asking for removal of duplicates. (Got another, identical error message when I sent that removal request.)
Chris - I assume the first picture, with the blue tarp background, is your actual linkage. The link I posted is a picture of the replacement motor for your motorhome. If you look closely, you can see the flat sides on the motor shaft.
What you circled in the second picture is a pin/bushing, similar to the two eyeteeth is used to replacing.

The nylon ones are easy and cheap to make. Machined metal (bronze or similar) would be more durable but more expensive.
I doubt OEM replacements are available ... Dorman replacements are equal to or better than the originals.
