How to Reduce the Wiper Blade Stroke?
2 Answers
A flat-head screwdriver and two adjustable wrenches. Lift the wiper blade upward along the angle of the windshield for a short distance, then lift the wiper arm outward. Remove the wiper blade to prevent accidental damage during maintenance. Place a towel over the wiper arm to avoid scratching the paint during adjustment. Use one wrench to secure the bent end and gently twist the other wrench in different directions with the second wrench.
The wiper stroke is too large, so I often adjust it to be smaller myself. The method is actually quite simple. First, park the car and turn off the engine, then open the hood and locate the connection point of the wiper arm. There's a fixing screw there; gently loosen it with a wrench. Move the wiper arm to the desired position—usually moving it slightly to the right will reduce the stroke. Be careful not to move it too forcefully to avoid damaging the linkage or the windshield. After adjusting, tighten the screw to secure it, close the hood, and start the car to test if the wiper operates smoothly. I've encountered issues where the stroke was too large and the wiper hit the car frame, which is usually due to aging linkage or improper installation. Regularly cleaning rust from the wiper arm can help prevent this. For safety, take your time with the adjustments and don’t rush to drive afterward. Make sure everything is checked properly before hitting the road to avoid any issues while driving—clear visibility is crucial for safe driving.
