The wiper arm has stripped out were the wiper arm attaches to the spline shaft. If anyone has any idea as to were I can find a new wiper arm assy for a 2005 HR Imperial, I would be appreciated. By the way I called Monaco and they said they didn't have any in stock and the original manufacturer is out of business. So any other ideas please. ( the arm has a 38 degree bend in the shaft ).

Now this may sound like a Rube Goldberg fix.
Ours did the same thing. With a brake in between rain storms while camping I cut from a lid of a dog food can a curve strip of metal, about 1/2 inch wide following the curve of the outer edge of the lid, form it into a cone shape not overlapping the ends. Used JB weld to glue the shim it to the arm, (you don't need a lot of JB Weld). Reinstall the arm back on the post an tight down about 3/4 of the way. 12hours later tighten it up. Been working for a year so far. It get a good work out here in Oregon. I used scissors to cut the metal it all I had.

I was going to recommend Diesel Equipment as Bill did. They were the OEM providers when your coach was built. They are now the distributor for TruVision. They may have something that will work.

Had a similar issue, used a spiral lock washer and lock nut, arm no longer slips.

On an old Kenworth I drive at work the window winder shaft stripped. The handle would just spin on the shaft. We didn't have time to replace the winder unit so we JB welded it back on the shaft. It has been 5 months since and it is still there and it gets used alot.

Another fan of JB weld. Possible fix if you can't find another part.

Mine did the same thing. Was told to take a dental pick and clean out the splines as wiper arm is soft and the pivot shaft is hard steel and the splines gets clogged with the softer wiper arm material. I cleaned mine spotless and tightened the nut and it has worked great for years...
