Yep. I've bent the arm, too. The bigger reason I believe everyone is eluding to here is the fact that the pivot point where the wiper arm meets the mount through the glass corrodes and that corrosion limits the amount of tension the spring can apply.


I regularly soak mine with penetrating lubricant and cycle it through the 90 degrees of motion a number of times.
