Broken wiper arm


Had a wiper arm break off about two inches from where the nut is that attaches it to the motor shaft. This is an arm about two feet long and is for a 32" wiper blade. I've tried to find an arm that would work at several local auto/truck salvage yards, but nobody had one.
Haven't used J B Weld much, but thought that might fix it. For anyone familiar with J B Weld, do you think it would be strong enough to hold on this wiper arm? Or, should I just get a new arm?

Go for the new one. That arm takes a LOT of stress, especially when on high. THe high speed and direction change at each end will not give JB Weld enough contact area to work. If you could splint it on at least 3 sides with steel, it might hold, but I wouldn't want to bet the farm on it.

Call whoever made your coach and order a new arm. JB will not hold. If the stress was enough to break the arm, JB weld won't stand a chance

Let me clarify. I broke the arm myself pulling it away from the windshield to wash it, it didn't break when it was operating.
But, if those of you familiar with J B Weld don't think it will hold, I'll defer to your judgement look for a new arm.

Several MH manufacturers used Denso wipers. Go here Windshield Washers | DENSO Heavy Duty to download the catalog, they have them listed by Manufacturer. Tried to upload it but the file is over the 3MB limit.

Fully agree, I broke one last spring. After so many times pulling it back it gets week. Denso made mine and a local supply house had one in stock.. about $75 I believe.
