Front windshield wiper Volvo Amazon (B18) (Auto Lite)

Jerky wiper movement, one wiper arm lagging behind, or blades that miss at the edges can often point to worn links and dried-out rubber bushings in the wiper mechanism. On the 122 with the B18 engine and Auto Lite system, play in the linkage is a common check point – when bushings and hubs wear in, the motion becomes uneven and the blades apply the wrong pressure against the windshield.
