A solution for tricky wiper arms?

Laser Tools’ new windscreen wiper lever tool (9088) is designed to make wiper arm removal fast, easy and damage-free.

Modern windscreen wiper arms can be notoriously difficult to remove due to their tapered and splined mounting, corrosion buildup and high spring tension, according to Laser Tools, and, over time, exposure to the elements can make them seize onto the spindle, turning what should be a quick job into a frustrating struggle.

This tool uses a hook and lever or hook and pull action, providing the necessary force to free stubborn arms without excessive prying or damage to surrounding bodywork – but why are wiper arms so hard to remove?

A tapered and splined fit creates a tight press-fit between components, making them resistant to removal; however, this secure connection can be further complicated by corrosion and seizure, as moisture, dirt and road salt may cause the arm to bind to the spindle.

Additionally, high spring tension, which is essential for maintaining good blade contact with the windscreen, adds to the difficulty of removing the component.

Laser Tools believe its latest tool is a “must-have” for professional technicians and DIY enthusiasts alike.
