Attention: TDR Forum Junkies 
comrades! just a little advice on windshield wipers and the angle they hit the glass at...have gone through 3 sets of blades ( expensive and cheapos ) with no resolution to chatter of the passenger side blade....at the end of my patience yesterday, i went out and looked at the angle of the wiper assembly vs the glass. drivers side was 90 degrees ( with my speed square on the surface of the glass ) the passenger side was at 60 degrees - so somehow it had gotten bent. put crescent wrench on wiper arm and re bent to match drivers assembly. chatter problem gone! the only thing i can think of is that the motor bent the arm over last winter while stuck in the ice/snow. and, yes, i have a 9 year old sense of humor but im 50. 
cheers!
cheers!
