Search the forum for "wiper blades". Lots of discussion, specifically how to replace the wiper arms with arms from other Subie models so that you can use ANY off-the-shelf blade. Bosch Icons seem to be a forum favorite.

 

It's well documented on here that standard wiper blades do not fit the driver's side of the Tribeca due to a difference in the wiper arm's hook width.

The quote you got from the dealership was probably for a new metal wiper assembly - you can buy refills for a lot less money than that. Trico also makes inexpensive refills for it.

That being said, I would recommend this option instead: http://www.sb9t.com/forums/showthread.php?t=3115

For less than $40 you can replace the whole arm and use whatever blades you want. I'm very happy with Bosch Icon blades for performance and longevity.

 

So this is applicable acrossed the board for all tribca years, kind of a pain but I guess it is what it is

 

Also, I moved your thread to the correct forum

Just replace the insert, it's easy and cheap. The arm itself isn't a wear item. I find I need to replace the insert 2x per year, spring and fall. I do it when I am changing over my winter tires.
