1. Switch off ignition and ensure the wiper is in its parked position.
2. Lift old arm slightly; remove nut or fastener beneath any cap.
3. Pull old arm straight off along the shaft axis—avoid harsh lateral twisting.
4. Clean the output shaft spline (lightly brush if corroded).
5. Align new arm at original angle, press onto spline and tighten nut.
6. If also replacing blade: attach compatible rear blade to arm tip now.
7. Spray washer and test (with blade installed) to confirm sweep path & park angle.

• Periodically check spring tension; low pressure causes localized skipping.
• Clear grit around the pivot to prevent stiffness or uneven sweep.
• Avoid forcibly bending the arm body or twisting the spline seat.
• In freezing conditions, de-ice before lifting the arm to prevent spring fatigue or breakage.
• If sweep becomes irregular, first rule out blade rubber wear, then inspect arm pivot and spring.

Is the blade included?

No. This is the rear wiper arm only. Blade must be purchased separately.

Why replace only the arm?

Spring fatigue, deformation or pivot wear can cause uneven blade pressure and streaking even with a new blade.

Can I keep using the old blade?

Temporarily yes, but for best visibility replace an aged blade at the same time.

Any special tools needed?

Usually just the correct size socket / wrench.

Are streaks caused by the arm?

Most streaks come from worn rubber; only pressure loss or uneven sweep links to the arm.

Do you support bulk or private label?

Yes—custom packaging & labeling available with MOQ.
