Windscreen wiper arms – fitment and installation
A wiper arm transfers motion from the linkage to the blade and presses it against the glass. Different vehicles use different arm lengths, angles and mountings.
How to choose a wiper arm
Check OE number, side, connection to the drive spindle, arm length and blade attachment. Confirm whether the product includes only the arm.
Wear symptoms and installation
Streaks or juddering may come from a worn blade, incorrect arm pressure or dirty glass. Avoid letting the bare arm snap against the windscreen.
