Wiper Arm Adjustment Tool ±20° for Hook Style Arms VAG 3358A

A wiper arm adjustment tool used to check and correct the angle between a hook style wiper arm and the windscreen. Getting the arm angle right can help resolve poor blade contact, streaking and uneven wiping, and this pattern is equivalent to VAG OEM 3358A.

Used for vehicle maintenance, servicing and repair work where wiper blades are not sitting properly on the glass. It suits garages, workshops and anyone dealing with everyday wiper alignment issues on vehicles with hook style arms, especially when a blade is missing part of the screen, chattering or leaving water behind. When the arm position is slightly out, this gives a straightforward way to inspect and adjust it rather than replacing parts unnecessarily.

The tool mounts at the front of the wiper arm, with the angle then adjusted using a wrench. Its measuring range of ±20° gives enough scope for checking and correcting common alignment faults. It is made specifically for hook style wiper arms and is not suitable for newer aero style arms, so it is worth checking the arm type before use. For regular servicing work, having the correct tool to hand can make wiper alignment quicker and more consistent.
