4. Installation Instructions
Follow these steps carefully to replace your rear windshield wiper arm. It is recommended to consult a professional if you are unsure about any step.
4.1. Tools Required
- Wrench or socket set (appropriate size for wiper arm nut)
- Flathead screwdriver (optional, for prying cover)
- Protective gloves (recommended)
4.2. Removal of Old Wiper Arm
- Prepare the Vehicle: Ensure the vehicle is turned off and the ignition key is removed.
- Locate the Wiper Arm: Identify the rear windshield wiper arm.
- Remove Nut Cover: Carefully lift the plastic cap or cover at the base of the wiper arm where it attaches to the wiper motor shaft. This may require a small flathead screwdriver to gently pry it open.
- Loosen Nut: Using the appropriate wrench or socket, loosen and remove the nut securing the wiper arm to the shaft. Keep this nut for reinstallation.
- Remove Wiper Arm: Gently pull the old wiper arm straight off the splined shaft. If it is stuck, a wiper arm puller tool may be necessary. Avoid excessive force to prevent damage to the wiper motor shaft.

4.3. Installation of New Wiper Arm
- Position New Arm: Place the new Dorman 42836 wiper arm onto the splined shaft. Ensure the wiper arm is positioned correctly on the windshield, typically resting just above the bottom edge of the glass when in its parked position.
- Secure with Nut: Reinstall the nut removed in step 4.2.4. Tighten the nut securely, but do not overtighten, as this can damage the splines or the motor.
- Replace Nut Cover: Snap the plastic cap or cover back over the nut.
- Attach Wiper Blade (if applicable): If you are also installing a new wiper blade, attach it to the new wiper arm according to the blade manufacturer's instructions.

5. Operation and Testing
After installation, it is important to test the functionality of the new wiper arm.
- Clear Obstructions: Ensure there are no obstructions on the rear windshield that could impede the wiper's movement.
- Activate Wipers: Turn on your vehicle's ignition and activate the rear windshield wiper function.
- Observe Movement: Observe the wiper arm's full range of motion. It should move smoothly across the glass without hitting the vehicle body or trim.
- Check Parking Position: When the wipers are turned off, the arm should return to its correct parked position. If the parking position is incorrect, the arm may need to be re-indexed on the splined shaft.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Dorman wiper arm.
- Regular Inspection: Periodically inspect the wiper arm for any signs of damage, corrosion, or loose connections.
- Cleanliness: Keep the wiper arm and the area around its base clean from dirt, debris, and ice, which can hinder its movement.
- Wiper Blade Replacement: Replace the wiper blade regularly (typically every 6-12 months) or when streaking, chattering, or reduced visibility occurs. A worn blade can put undue stress on the wiper arm.
- Avoid Forcing: Do not manually force the wiper arm against a frozen windshield, as this can damage the arm or the wiper motor.
7. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
