Tools you will need
- 14mm socket and ratchet
- Torque wrench
- Erasable marker
Parts and supplies
- Windshield wiper arms
Steps
- Mark the wiper arm positions
With the arms parked, mark each blade's resting position on the windshield using an erasable marker. Open the hood and remove the small covers over the arm nuts.
- Remove the old wiper arms
Remove each 14mm nut and gently rock the arm at its pivot to free it from the splines. Avoid levering against the glass, then lift the arms away.
- Install the replacement arms
Align each new arm with its original windshield mark and start the nut by hand. Tighten the arm fastener to the vehicle's specification, repeating the process on the other side.
- Test wiper sweep and parking
Replace the nut covers and close the hood. Operate the wipers with washer fluid to confirm they park correctly and do not contact the trim or each other; erase the alignment marks.
Check your vehicle’s repair manual for exact specifications and fit.
