Gravity Windshield Wipers Screechy?

[raleighone]

My passenger side blade has always been super screechy on it's way back down from wiping the window, no matter how wet/dry. I just got an Air loaner and immediately noticed how smooth the blades went over the glass without any screech.

Is it possible mine needs an adjustment or does everyone's Gravity do this? (It did this with new/clean blades, btw)
