Wiper Arms
WARNING: This page is about a different car, the 2011 Jaguar XKR, 2011 Jaguar XK, 2010 Jaguar XKR, and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.
The wiper arms are positively located on tapered splines on the wiper linkage spindles.
The wiper arm has a spindle point, midway between the spindle attachment and the blade. A tension spring is connected to the wiper arm on each side of the spindle point and applies pressure to maintain the wiper blade in contact with the windshield.
The wiper blades are attached to the wiper arms with clips that allow the blade to pivot. The wiper blades comprise a sprung steel curved backbone which applies pressure evenly to the windshield, to which is applied the wiping lip to the bottom surface. An aerofoil section presses the blades onto the windshield at high vehicle speeds.
